The Buyid dynasty or the Buyids known as Buwaihids, Buyahids, or Buyyids, was a Shia Iranian dynasty of Daylamite origin. Coupled with the rise of other Iranian dynasties in the region, the approximate century of Buyid rule represents the period in Iranian history sometimes called the'Iranian Intermezzo' since, after the Muslim conquest of Persia, it was an interlude between the rule of the Abbasid Caliphate and the Seljuk Empire; the Buyid dynasty was founded by'Ali ibn Buya, who in 934 conquered Fars and made Shiraz his capital. His younger brother Hasan ibn Buya conquered parts of Jibal in the late 930s, by 943 managed to capture Ray, which he made his capital. In 945, the youngest brother, Ahmad ibn Buya, made Baghdad his capital, he received the honorific title of Mu'izz al-Dawla. The eldest,'Ali, was given the title of'Imad al-Dawla, Hasan was given the title of Rukn al-Dawla; as Daylamite Iranians, the Buyids consciously revived symbols and practices of Iran's Sasanian Empire. Beginning with'Adud al-Dawla, they used the ancient Sasanian title Shahanshah "king of kings".
At its greatest extent, the Buyid dynasty encompassed territory of most of today's Iran, Iraq and Syria, along with parts of Oman, the UAE, Turkey and Pakistan. During the 10th and 11th centuries, just prior to the invasion of the Seljuq Turks, the Buyids were the most influential dynasty in the Middle East. Under king'Adud al-Dawla, it became the most powerful dynasty in the Middle East; the word Būya is a Middle Persian name ending in the diminutive ـویه. The Buyids were descendants of a Zoroastrian from Daylam, he had a son named Buya, a fisherman from Lahijan, left Zoroastrianism and converted to Islam. Buya had three sons, named Ahmad,'Ali, Hasan, who would carve the Buyid kingdom together. Most historians agree; the Buyids claimed royal lineage from 15th king of the Sasanian Empire. The founder of the dynasty,'Ali ibn Buya, was a soldier in the service of the Daylamite warlord Makan ibn Kaki, but changed his adherence to the Iranian ruler Mardavij, who had established the Ziyarid dynasty, was himself related to the ruling dynasty of Gilan, a region bordering Dailam.'Ali was joined by his two younger brothers, Hasan ibn Buya and Ahmad ibn Buya.
In 932,'Ali was given Karaj as his fief, thus was able to enlist other Daylamites into his own army. However,'Ali's independent actions made Mardavij plan to have him killed,'Ali was informed of Mardavij's plan by the latter's own vizier; the Buyids brother, with 400 of their Daylamite supporters fled to Fars, where they managed to take control of Arrajan. However, the Buyids and the Abbasid general Yaqut shortly came into a struggle for the control of Fars, which the Buyids emerged victorious in; this victory opened the way for the conquest of the capital of Fars, Shiraz.'Ali made an alliance with the landowners of Fars, which included the Fasanjas family, which would produce many prominent statesmen for the Buyids. Furthermore,'Ali to enlist more soldiers, which included the Turks, who were made part of cavalry.'Ali sent his brother Ahmad on an expedition to Kirman, but was forced to withdraw from them after opposition from the Baloch people and the Qafs. However, who sought to depose the Abbasid caliph of Baghdad and recreate a Zoroastrian Iranian Empire, shortly wrested Khuzestan from the Abbasids and forced'Ali to recognize him as his suzerain.
Luckily for the Buyids, Mardavij was shortly assassinated in 935, which caused chaos in the Ziyarid territories, a perfect situation for the Buyid brothers. In 945, Ahmad entered Iraq and made the Abbasid Caliph his vassal, at the same receiving the laqab Mu'izz ad-Dawla, while'Ali was given the laqab Imād al-Dawla, Hasan was given the laqab Rukn al-Dawla. In addition to the other territories the Buyids had conquered, Kirman was conquered in 967, the Jazira and Gorgan. After this, the Buyids went into a slow decline, with pieces of the confederation breaking off and local dynasties under their rule becoming de facto independent; the death of Adud al-Dawla is considered the starting point of the decline of the Buyid dynasty. When he made the death of his father public, he was given the title of "Samsam al-Dawla". However, Adud's other son, Shirdil Abu'l-Fawaris, challenged the authority of Samsam al-Dawla, resulting in a civil war. Meanwhile, a Marwanid chieftain named Badh, seized Diyabakr and forced Samsam al-Dawla to recognize him as the vassal ruler of the region.
Furthermore, Mu'ayyad al-Dawla died during this period, he was succeeded by Fakhr al-Dawla, who with the aid of Mu'ayyad al-Dawla's vizier Sahib ibn'Abbad became the ruler of Mu'ayyad al-Dawla's possessions. Another son of Adud al-Dawla, Abu Tahir Firuzshah, established himself as the ruler of Basra and took the title of "Diya' al-Dawla", while another son, Abu'l-Husain Ahmad, established himself as the ruler of Khuzistan, taking the title of "Taj al-Dawla". Shirdil Abu'l-Fawaris seize
Arabic is a Central Semitic language that first emerged in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. It is named after the Arabs, a term used to describe peoples living in the area bounded by Mesopotamia in the east and the Anti-Lebanon mountains in the west, in northwestern Arabia, in the Sinai Peninsula. Arabic is classified as a macrolanguage comprising 30 modern varieties, including its standard form, Modern Standard Arabic, derived from Classical Arabic; as the modern written language, Modern Standard Arabic is taught in schools and universities, is used to varying degrees in workplaces and the media. The two formal varieties are grouped together as Literary Arabic, the official language of 26 states, the liturgical language of the religion of Islam, since the Quran and Hadith were written in Arabic. Modern Standard Arabic follows the grammatical standards of Classical Arabic, uses much of the same vocabulary. However, it has discarded some grammatical constructions and vocabulary that no longer have any counterpart in the spoken varieties, has adopted certain new constructions and vocabulary from the spoken varieties.
Much of the new vocabulary is used to denote concepts that have arisen in the post-classical era in modern times. Due to its grounding in Classical Arabic, Modern Standard Arabic is removed over a millennium from everyday speech, construed as a multitude of dialects of this language; these dialects and Modern Standard Arabic are described by some scholars as not mutually comprehensible. The former are acquired in families, while the latter is taught in formal education settings. However, there have been studies reporting some degree of comprehension of stories told in the standard variety among preschool-aged children; the relation between Modern Standard Arabic and these dialects is sometimes compared to that of Latin and vernaculars in medieval and early modern Europe. This view though does not take into account the widespread use of Modern Standard Arabic as a medium of audiovisual communication in today's mass media—a function Latin has never performed. During the Middle Ages, Literary Arabic was a major vehicle of culture in Europe in science and philosophy.
As a result, many European languages have borrowed many words from it. Arabic influence in vocabulary, is seen in European languages Spanish and to a lesser extent Portuguese, Catalan, owing to both the proximity of Christian European and Muslim Arab civilizations and 800 years of Arabic culture and language in the Iberian Peninsula, referred to in Arabic as al-Andalus. Sicilian has about 500 Arabic words as result of Sicily being progressively conquered by Arabs from North Africa, from the mid-9th to mid-10th centuries. Many of these words relate to related activities; the Balkan languages, including Greek and Bulgarian, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has influenced many languages around the globe throughout its history; some of the most influenced languages are Persian, Spanish, Kashmiri, Bosnian, Bengali, Malay, Indonesian, Punjabi, Assamese, Sindhi and Hausa, some languages in parts of Africa. Conversely, Arabic has borrowed words from other languages, including Greek and Persian in medieval times, contemporary European languages such as English and French in modern times.
Classical Arabic is the liturgical language of 1.8 billion Muslims, Modern Standard Arabic is one of six official languages of the United Nations. All varieties of Arabic combined are spoken by as many as 422 million speakers in the Arab world, making it the fifth most spoken language in the world. Arabic is written with the Arabic alphabet, an abjad script and is written from right to left, although the spoken varieties are sometimes written in ASCII Latin from left to right with no standardized orthography. Arabic is a Central Semitic language related to the Northwest Semitic languages, the Ancient South Arabian languages, various other Semitic languages of Arabia such as Dadanitic; the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include: The conversion of the suffix-conjugated stative formation into a past tense; the conversion of the prefix-conjugated preterite-tense formation into a present tense.
The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms. The development of an internal passive. There are several features which Classical Arabic, the modern Arabic varieties, as well as the Safaitic and Hismaic inscriptions share which are unattested in any other Central Semitic language variety, including the Dadanitic and Taymanitic languages of the northern Hejaz; these features are evidence of common descent from Proto-Arabic. The following features can be reconstructed with confidence for Proto-Arabic: negative particles m *mā.
Euclid, sometimes called Euclid of Alexandria to distinguish him from Euclid of Megara, was a Greek mathematician referred to as the "founder of geometry" or the "father of geometry". He was active in Alexandria during the reign of Ptolemy I, his Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching mathematics from the time of its publication until the late 19th or early 20th century. In the Elements, Euclid deduced the theorems of what is now called Euclidean geometry from a small set of axioms. Euclid wrote works on perspective, conic sections, spherical geometry, number theory, mathematical rigour; the English name Euclid is the anglicized version of the Greek name Εὐκλείδης, which means "renowned, glorious". Few original references to Euclid survive, so little is known about his life, he was born c. 325 BC, although the place and circumstances of both his birth and death are unknown and may only be estimated relative to other people mentioned with him.
He is mentioned by name by other Greek mathematicians from Archimedes onward, is referred to as "ὁ στοιχειώτης". The few historical references to Euclid were written by Proclus c. 450 AD, centuries after Euclid lived. A detailed biography of Euclid is given by Arabian authors, for example, a birth town of Tyre; this biography is believed to be fictitious. If he came from Alexandria, he would have known the Serapeum of Alexandria, the Library of Alexandria, may have worked there during his time. Euclid's arrival in Alexandria came about ten years after its founding by Alexander the Great, which means he arrived c. 322 BC. Proclus introduces Euclid only in his Commentary on the Elements. According to Proclus, Euclid belonged to Plato's "persuasion" and brought together the Elements, drawing on prior work of Eudoxus of Cnidus and of several pupils of Plato Proclus believes that Euclid is not much younger than these, that he must have lived during the time of Ptolemy I because he was mentioned by Archimedes.
Although the apparent citation of Euclid by Archimedes has been judged to be an interpolation by editors of his works, it is still believed that Euclid wrote his works before Archimedes wrote his. Proclus retells a story that, when Ptolemy I asked if there was a shorter path to learning geometry than Euclid's Elements, "Euclid replied there is no royal road to geometry." This anecdote is questionable since it is similar to a story told about Menaechmus and Alexander the Great. Euclid died c. 270 BC in Alexandria. In the only other key reference to Euclid, Pappus of Alexandria mentioned that Apollonius "spent a long time with the pupils of Euclid at Alexandria, it was thus that he acquired such a scientific habit of thought" c. 247–222 BC. Because the lack of biographical information is unusual for the period, some researchers have proposed that Euclid was not a historical personage, that his works were written by a team of mathematicians who took the name Euclid from Euclid of Megara. However, this hypothesis is not well accepted by scholars and there is little evidence in its favor.
Although many of the results in Elements originated with earlier mathematicians, one of Euclid's accomplishments was to present them in a single, logically coherent framework, making it easy to use and easy to reference, including a system of rigorous mathematical proofs that remains the basis of mathematics 23 centuries later. There is no mention of Euclid in the earliest remaining copies of the Elements, most of the copies say they are "from the edition of Theon" or the "lectures of Theon", while the text considered to be primary, held by the Vatican, mentions no author; the only reference that historians rely on of Euclid having written the Elements was from Proclus, who in his Commentary on the Elements ascribes Euclid as its author. Although best known for its geometric results, the Elements includes number theory, it considers the connection between perfect numbers and Mersenne primes, the infinitude of prime numbers, Euclid's lemma on factorization, the Euclidean algorithm for finding the greatest common divisor of two numbers.
The geometrical system described in the Elements was long known as geometry, was considered to be the only geometry possible. Today, that system is referred to as Euclidean geometry to distinguish it from other so-called non-Euclidean geometries that mathematicians discovered in the 19th century; the Papyrus Oxyrhynchus 29 is a fragment of the second book of the Elements of Euclid, unearthed by Grenfell and Hunt 1897 in Oxyrhynchus. More recent scholarship suggests a date of 75–125 AD; the classic translation of T. L. Heath, reads: If a straight line be cut into equal and unequal segments, the rectangle contained by the unequal segments of the whole together with the square on the straight line between the points of section is equal to the square on the half. In addition to the Elements, at least five works of Euclid have survived to the present day, they follow the same logical structure with definitions and proved propositions. Data deals with the nature and implications of "given" information in geometrical problems.
Constantinople was the capital city of the Roman Empire, of the Byzantine Empire, of the brief Crusader state known as the Latin Empire, until falling to the Ottoman Empire. It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, dedicated on 11 May 330; the city was located in what is now the core of modern Istanbul. From the mid-5th century to the early 13th century, Constantinople was the largest and wealthiest city in Europe; the city was famed for its architectural masterpieces, such as the Greek Orthodox cathedral of Hagia Sophia, which served as the seat of the Ecumenical Patriarchate, the sacred Imperial Palace where the Emperors lived, the Galata Tower, the Hippodrome, the Golden Gate of the Land Walls, the opulent aristocratic palaces lining the arcaded avenues and squares. The University of Constantinople was founded in the fifth century and contained numerous artistic and literary treasures before it was sacked in 1204 and 1453, including its vast Imperial Library which contained the remnants of the Library of Alexandria and had over 100,000 volumes of ancient texts.
It was instrumental in the advancement of Christianity during Roman and Byzantine times as the home of the Ecumenical Patriarch of Constantinople and as the guardian of Christendom's holiest relics such as the Crown of Thorns and the True Cross. Constantinople was famed for its complex defences; the first wall of the city was erected by Constantine I, surrounded the city on both land and sea fronts. In the 5th century, the Praetorian Prefect Anthemius under the child emperor Theodosius II undertook the construction of the Theodosian Walls, which consisted of a double wall lying about 2 kilometres to the west of the first wall and a moat with palisades in front; this formidable complex of defences was one of the most sophisticated of Antiquity. The city was built intentionally to rival Rome, it was claimed that several elevations within its walls matched the'seven hills' of Rome; because it was located between the Golden Horn and the Sea of Marmara the land area that needed defensive walls was reduced, this helped it to present an impregnable fortress enclosing magnificent palaces and towers, the result of the prosperity it achieved from being the gateway between two continents and two seas.
Although besieged on numerous occasions by various armies, the defences of Constantinople proved impregnable for nearly nine hundred years. In 1204, the armies of the Fourth Crusade took and devastated the city, its inhabitants lived several decades under Latin misrule. In 1261 the Byzantine Emperor Michael VIII Palaiologos liberated the city, after the restoration under the Palaiologos dynasty, enjoyed a partial recovery. With the advent of the Ottoman Empire in 1299, the Byzantine Empire began to lose territories and the city began to lose population. By the early 15th century, the Byzantine Empire was reduced to just Constantinople and its environs, along with Morea in Greece, making it an enclave inside the Ottoman Empire. According to Pliny the Elder in his Natural History, the first known name of a settlement on the site of Constantinople was Lygos, a settlement of Thracian origin founded between the 13th and 11th centuries BC; the site, according to the founding myth of the city, was abandoned by the time Greek settlers from the city-state of Megara founded Byzantium in around 657 BC, across from the town of Chalcedon on the Asiatic side of the Bosphorus.
The origins of the name of Byzantion, more known by the Latin Byzantium, are not clear, though some suggest it is of Thraco-Illyrian origin. The founding myth of the city has it told that the settlement was named after the leader of the Megarian colonists, Byzas; the Byzantines of Constantinople themselves would maintain that the city was named in honour of two men and Antes, though this was more just a play on the word Byzantion. The city was renamed Augusta Antonina in the early 3rd century AD by the Emperor Septimius Severus, who razed the city to the ground in 196 for supporting a rival contender in the civil war and had it rebuilt in honour of his son Marcus Aurelius Antoninus, popularly known as Caracalla; the name appears to have been forgotten and abandoned, the city reverted to Byzantium/Byzantion after either the assassination of Caracalla in 217 or, at the latest, the fall of the Severan dynasty in 235. Byzantium took on the name of Kōnstantinoupolis after its refoundation under Roman emperor Constantine I, who transferred the capital of the Roman Empire to Byzantium in 330 and designated his new capital as Nova Roma'New Rome'.
During this time, the city was called'Second Rome','Eastern Rome', Roma Constantinopolitana. As the city became the sole remaining capital of the Roman Empire after the fall of the West, its wealth and influence grew, the city came to have a multitude of nicknames; as the largest and wealthiest city in Europe during the 4th–13th centuries and a centre of culture and education of the Mediterranean basin, Constantinople came to be known by prestigious titles such as Basileuousa and Megalopol
Aristotle was a philosopher during the Classical period in Ancient Greece, the founder of the Lyceum and the Peripatetic school of philosophy and Aristotelian tradition. Along with his teacher Plato, he is considered the "Father of Western Philosophy", his writings cover many subjects – including physics, zoology, logic, aesthetics, theatre, rhetoric, linguistics, economics and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him, it was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry; as a result, his philosophy has exerted a unique influence on every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in the city of Stagira in Northern Greece, his father, died when Aristotle was a child, he was brought up by a guardian. At seventeen or eighteen years of age, he joined Plato's Academy in Athens and remained there until the age of thirty-seven.
Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored Alexander the Great beginning in 343 BC. He established a library in the Lyceum which helped him to produce many of his hundreds of books on papyrus scrolls. Though Aristotle wrote many elegant treatises and dialogues for publication, only around a third of his original output has survived, none of it intended for publication; the fact that Aristotle was a pupil of Plato contributed to his former views of Platonism, following Plato's death, Aristotle developed an increased interest in natural sciences and adopted the position of immanent realism. Aristotle's views on physical science profoundly shaped medieval scholarship, their influence extended from Late Antiquity and the Early Middle Ages into the Renaissance, were not replaced systematically until the Enlightenment and theories such as classical mechanics. Some of Aristotle's zoological observations found in his biology, such as on the hectocotyl arm of the octopus, were disbelieved until the 19th century.
His works contain the earliest known formal study of logic, studied by medieval scholars such as Peter Abelard and John Buridan. Aristotle's influence on logic continued well into the 19th century He influenced Islamic thought during the Middle Ages, as well as Christian theology the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church. Aristotle was revered among medieval Muslim scholars as "The First Teacher" and among medieval Christians like Thomas Aquinas as "The Philosopher", his ethics, though always influential, gained renewed interest with the modern advent of virtue ethics, such as in the thinking of Alasdair MacIntyre and Philippa Foot. In general, the details of Aristotle's life are not well-established; the biographies written in ancient times are speculative and historians only agree on a few salient points. Aristotle, whose name means "the best purpose" in Ancient Greek, was born in 384 BC in Stagira, about 55 km east of modern-day Thessaloniki.
His father Nicomachus was the personal physician to King Amyntas of Macedon. Both of Aristotle's parents died when he was about thirteen, Proxenus of Atarneus became his guardian. Although little information about Aristotle's childhood has survived, he spent some time within the Macedonian palace, making his first connections with the Macedonian monarchy. At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Plato's Academy, he remained there for nearly twenty years before leaving Athens in 348/47 BC. The traditional story about his departure records that he was disappointed with the Academy's direction after control passed to Plato's nephew Speusippus, although it is possible that he feared the anti-Macedonian sentiments in Athens at that time and left before Plato died. Aristotle accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor. After the death of Hermias, Aristotle travelled with his pupil Theophrastus to the island of Lesbos, where together they researched the botany and zoology of the island and its sheltered lagoon.
While in Lesbos, Aristotle married Hermias's adoptive daughter or niece. She bore him a daughter, whom they named Pythias. In 343 BC, Aristotle was invited by Philip II of Macedon to become the tutor to his son Alexander. Aristotle was appointed as the head of the royal academy of Macedon. During Aristotle's time in the Macedonian court, he gave lessons not only to Alexander, but to two other future kings: Ptolemy and Cassander. Aristotle encouraged Alexander toward eastern conquest and Aristotle's own attitude towards Persia was unabashedly ethnocentric. In one famous example, he counsels Alexander to be "a leader to the Greeks and a despot to the barbarians, to look after the former as after friends and relatives, to deal with the latter as with beasts or plants". By 335 BC, Aristotle had returned to Athens. Aristotle conducted courses at the school for the next twelve years. While in Athens, his wife Pythias died and Aristotle became involved with Herpyllis of Stagira, who bore him a son whom he named after his father, Nicomachus.
According to the Suda, he had an erômenos, Palaephatus of Abydus. This period in Athens, between 335 and 323 BC, is when Aristotle is believed to have composed many of his works, he wrote many dialogues. Those works that have survived are in treatise form and were not
Arabs are a population inhabiting the Arab world. They live in the Arab states in Western Asia, North Africa, the Horn of Africa and western Indian Ocean islands, they form a significant diaspora, with Arab communities established around the world. The first mention of Arabs is from the mid-ninth century BCE as a tribal people in eastern and southern Syria and the north of the Arabian Peninsula; the Arabs appear to have been under the vassalage of the Neo-Assyrian Empire, the succeeding Neo-Babylonian, Achaemenid and Parthian empires. Arab tribes, most notably the Ghassanids and Lakhmids, begin to appear in the southern Syrian Desert from the mid 3rd century CE onward, during the mid to stages of the Roman and Sasanian empires. Before the expansion of the Rashidun Caliphate, "Arab" referred to any of the nomadic and settled Semitic people from the Arabian Peninsula, Syrian Desert, North and Lower Mesopotamia. Today, "Arab" refers to a large number of people whose native regions form the Arab world due to the spread of Arabs and the Arabic language throughout the region during the early Muslim conquests of the 7th and 8th centuries and the subsequent Arabisation of indigenous populations.
The Arabs forged the Rashidun, Umayyad and the Fatimid caliphates, whose borders reached southern France in the west, China in the east, Anatolia in the north, the Sudan in the south. This was one of the largest land empires in history. In the early 20th century, the First World War signalled the end of the Ottoman Empire; this resulted in the defeat and dissolution of the empire and the partition of its territories, forming the modern Arab states. Following the adoption of the Alexandria Protocol in 1944, the Arab League was founded on 22 March 1945; the Charter of the Arab League endorsed the principle of an Arab homeland whilst respecting the individual sovereignty of its member states. Today, Arabs inhabit the 22 Arab states within the Arab League: Algeria, Comoros, Egypt, Jordan, Lebanon, Mauritania, Oman, Qatar, Saudi Arabia, Sudan, Tunisia, United Arab Emirates, Yemen; the Arab world stretches around 13 million km2, from the Atlantic Ocean in the west to the Arabian Sea in the east, from the Mediterranean Sea in the north to the Horn of Africa and the Indian Ocean in the southeast.
Beyond the boundaries of the League of Arab States, Arabs can be found in the global diaspora. The ties that bind Arabs are ethnic, cultural, identical, nationalist and political; the Arabs have their own customs, architecture, literature, dance, cuisine, society and mythology. The total number of Arabs are an estimated 450 million. Arabs are a diverse group in terms of religious practices. In the pre-Islamic era, most Arabs followed polytheistic religions; some tribes had adopted Christianity or Judaism, a few individuals, the hanifs observed monotheism. Today, about 93% of Arabs are adherents of Islam, there are sizable Christian minorities. Arab Muslims belong to the Sunni, Shiite and Alawite denominations. Arab Christians follow one of the Eastern Christian Churches, such as the Greek Orthodox or Greek Catholic churches. Other smaller minority religions are followed, such as the Bahá'í Faith and Druze. Arabs have influenced and contributed to diverse fields, notably the arts and architecture, philosophy, ethics, politics, music, cinema, medicine and technology in the ancient and modern history.
The earliest documented use of the word "Arab" to refer to a people appears in the Kurkh Monoliths, an Akkadian language record of the ninth century BCE Assyrian conquest of Aram, which referred to Bedouins of the Arabian Peninsula under King Gindibu, who fought as part of a coalition opposed to Assyria. Listed among the booty captured by the army of king Shalmaneser III of Assyria in the Battle of Qarqar are 1000 camels of "Gi-in-di-bu'u the ar-ba-a-a" or " Gindibu belonging to the Arab; the related word ʾaʿrāb is used to refer to Bedouins today, in contrast to ʿarab which refers to Arabs in general. The term Arab and ʾaʿrāb are mentioned around 40 times in pre-Islamic Sabaean inscriptions; the term Arab occurs in the titles of the Himyarite kings from the time of'Abu Karab Asad until MadiKarib Ya'fur. The term ʾaʿrāb is driven from the term Arab according to Sabaean grammar; the term is mentioned in Quranic verses referring to people who were living in Madina and it might be a south Arabian loan-word into Quranic language.
The oldest surviving indication of an Arab national identity is an inscription made in an archaic form of Arabic in 328 using the Nabataean alphabet, which refers to Imru' al-Qays ibn'Amr as "King of all the Arabs". Herodotus refers to the Arabs in the Sinai, southern Palestine, the frankincense region. Other ancient Greek historians like Agatharchides, Diodorus Siculus and Strabo mention Arabs living in Mesopotamia, in Egypt, southern Jordan, the Syrian steppe and in eastern Arabia. Inscriptions dating to the 6th century BCE in Yemen include the term "Arab"; the most popular Arab account holds that the word "Arab" came from an eponymous father called Ya'rub, the first to speak Arabic. A
Muhammad was the founder of Islam. According to Islamic doctrine, he was a prophet, sent to present and confirm the monotheistic teachings preached by Adam, Moses and other prophets, he is viewed as the final prophet of God in all the main branches of Islam, though some modern denominations diverge from this belief. Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings and practices forming the basis of Islamic religious belief. Born 570 CE in the Arabian city of Mecca, Muhammad was orphaned at the age of six, he was raised under the care of his paternal grandfather Abd al-Muttalib, upon his death, by his uncle Abu Talib. In years he would periodically seclude himself in a mountain cave named Hira for several nights of prayer; when he was 40, Muhammad reported being visited by Gabriel in the cave, receiving his first revelation from God. Three years in 610, Muhammad started preaching these revelations publicly, proclaiming that "God is One", that complete "submission" to God is the right way of life, that he was a prophet and messenger of God, similar to the other prophets in Islam.
The followers of Muhammad were few in number, experienced hostility from Meccan polytheists. He sent some of his followers to Abyssinia in 615 to shield them from prosecution, before he and his followers migrated from Mecca to Medina in 622; this event, the Hijra, marks the beginning of the Islamic calendar known as the Hijri Calendar. In Medina, Muhammad united the tribes under the Constitution of Medina. In December 629, after eight years of intermittent fighting with Meccan tribes, Muhammad gathered an army of 10,000 Muslim converts and marched on the city of Mecca; the conquest went uncontested and Muhammad seized the city with little bloodshed. In 632, a few months after returning from the Farewell Pilgrimage, he died. By the time of his death, most of the Arabian Peninsula had converted to Islam; the revelations, which Muhammad reported receiving until his death, form the verses of the Quran, regarded by Muslims as the verbatim "Word of God" and around which the religion is based. Besides the Quran, Muhammad's teachings and practices, found in the Hadith and sira literature, are upheld and used as sources of Islamic law.
The name Muhammad appears four times in the Quran. The Quran addresses Muhammad in the second person by various appellations. Muhammad is sometimes addressed by designations deriving from his state at the time of the address: thus he is referred to as the enwrapped in Quran 73:1 and the shrouded in Quran 74:1. In Sura Al-Ahzab 33:40 God singles out Muhammad as the "Seal of the prophets", or the last of the prophets; the Quran refers to Muhammad as Aḥmad "more praiseworthy". The name Abū al-Qāsim Muḥammad ibn ʿAbd Allāh ibn ʿAbd al-Muṭṭalib ibn Hāshim, begins with the kunya Abū, which corresponds to the English, father of; the Quran is the central religious text of Islam. Muslims believe; the Quran, provides minimal assistance for Muhammad's chronological biography. Important sources regarding Muhammad's life may be found in the historic works by writers of the 2nd and 3rd centuries of the Muslim era; these include traditional Muslim biographies of Muhammad, which provide additional information about Muhammad's life.
The earliest surviving written sira is Ibn Ishaq's Life of God's Messenger written c. 767 CE. Although the work was lost, this sira was used at great length by Ibn Hisham and to a lesser extent by Al-Tabari. However, Ibn Hisham admits in the preface to his biography of Muhammad that he omitted matters from Ibn Ishaq's biography that "would distress certain people". Another early history source is the history of Muhammad's campaigns by al-Waqidi, the work of his secretary Ibn Sa'd al-Baghdadi. Many scholars accept these early biographies as authentic. Recent studies have led scholars to distinguish between traditions touching legal matters and purely historical events. In the legal group, traditions could have been subject to invention while historic events, aside from exceptional cases, may have been only subject to "tendential shaping". Other important sources include the hadith collections, accounts of the verbal and physical teachings and traditions of Muhammad. Hadiths were compiled several generations after his death by followers including Muhammad al-Bukhari, Muslim ibn al-Hajjaj, Muhammad ibn Isa at-Tirmidhi, Abd ar-Rahman al-Nasai, Abu Dawood, Ibn Majah, Malik ibn Anas, al-Daraqutni.
Some Western academics cautiously view the hadith collections as accurate historical sources. Scholars such as Madelung do not reject the narrations which have been compiled in periods, but judge them in the context of history and on the basis of their compatibility with the events and figures. Muslim scholars on the other hand place a greater emph
