Vizier
A vizier is a high-ranking political advisor or minister. In modern usage, the term has been used for ministers in the Arab world, Turkey, East Africa Afghanistan, India and Uzbekistan. It is used in the only absolute Asian monarchy. It is given to the current King Hassanal Bolkiahs second brother, in Brunei, an ordinary vizier is known as Pengiran Temenggong. The word entered into English in 1562 from the Turkish vezir, Wazir itself has two possible etymologies, The most accepted etymology is that it is derived from the Arabic wazara, from the Semitic root W-Z-R. The word is mentioned in the Quran, where Aaron is described as the wazir of Moses, on the other hand, the presence of a Middle Persian word vizīr or vicīr, cognate to the Avestan vīcira, meaning decreer or arbitrator, could possibly indicate an Indo-European origin. In modern Turkey, there is no usage of vezir for any ministry as suggested in the description above, the Muslim office of vizier, which spread from the Persians, Turks and Mongols and neighboring peoples, arose under the first Abbasid caliphs.
The vizier stood between sovereign and subjects, representing the former in all matters touching the latter, if one such vizier is the prime minister, he may hold the title of Grand Vizier or another title. In Al-Andalus appointed by the Caliph of Cordoba, similarly in many of the emirates and sultanates of the taifas which the caliphate was broken up into. In Muslim Egypt, the most populous Arab country, Under the Fatimid Caliphs. Again since the end of Ottoman rule, remarkably since 1857 (i. e. before the last Wali, Ismail Pasha, was raised Khedive. During the days of the Ottoman Empire, the Grand Vizier was the—often de facto minister, second only to the Sultan and was the leader of the Divan. Vizier was the title of some Ottoman provincial governors, use of the title indicating a greater degree of autonomy for the province involved. In the Sherifian kingdom of Morocco, a Sadr al-Azam was in office until 22 November 1955, Grand Vizier, Chief Minister or Prime Minister. Wazir al-Amala, Minister for the Interior, Wazir al-Bahr, Minister of the Sea, i. e.
for the Navy/ Marine. Wazir al-Harb, Minister for the Army or Minister for War, Wazir al-Qalam, Minister of the Pen. In Oman the Hami/Sultans Chief minister was styled Wazir till 1966, Viziers to the Sultans of Zanzibar, since 1890 filled by British, known as First ministers, the British Resident s, an extremely direct form of indirect rule. Grand Viziers to the Sultan of Sokoto – this is however disputed, the title Waziri is apparently a derivative of this word, and is a highly regarded chieftaincy title in most of northern Nigeria
Rise of the Ottoman Empire
The foundation and rise of the Ottoman Empire is a period of history that started with the emergence of the Ottoman principality in c. 1299, and ended with the conquest of Constantinople on May 29,1453. For this reason, this period in the history has been described as the Proto-Imperial Era. Throughout most of period, the Ottomans were merely one of many competing states in the region. The cause of Ottoman success cannot be attributed to any single factor, the earlier part of this period, the fourteenth century, is particularly difficult for historians to study due to the scarcity of sources. Not a single written document survives from the reign of Osman I, the Ottomans, did not begin to record their own history until the fifteenth century, more than a hundred years after many of the events they describe. At the beginning of the thirteenth century Anatolia was divided between two powerful states, the Byzantine Empire in the west and the Anatolian Seljuks in the central plateau. Mongol pressure pushed nomadic Turkish tribes to migrate westward, into the now poorly-defended Byzantine territory, the power of these groups was largely dependent upon their ability to attract military manpower.
Western Anatolia was a hotbed of raiding activity, with warriors switching allegiance at will to whichever chief seemed most able to provide them opportunities for plunder. The Ottoman dynasty is named after the first independent ruler of the Ottoman polity, according to Ottoman tradition, he was descended from a Turkic tribe which migrated out of Central Asia in the wake of the Mongol Conquests. As evidenced by coins minted during his reign, Osmans father was named Ertuğrul, the origins of the Ottoman dynasty thus remain obscure, shrouded in myth and legend, and the identity of Osmans tribe and ancestors is not known for certain. Likewise, nothing is known about how Osman first established his principality as the sources, none of contemporary, provide many different. Osmans principality was initially supported by the manpower of nomadic Turkish groups. This Ottoman tribe was based not on blood-ties, but on political expedience, thus it was inclusive of all who wished to join, including people of Byzantine origin.
The Ottoman enterprise came to be led by several great families, at least one of which was of Greek Christian origin. Nevertheless, Islam played a role in Ottoman self-identity from the start, as evidenced by a land grant issued by Osmans son Orhan in 1324. Such a war was known as gaza, and a fighting in it was called a gazi. Beginning in the 1980s, historians began to criticize Witteks thesis. Scholars now recognize that the terms gaza and gazi did not have religious connotations for the early Ottomans
1509 Constantinople earthquake
The 1509 Constantinople earthquake, referred to as The Lesser Judgment Day by contemporaries, occurred in the Sea of Marmara on 10 September 1509 at about 10pm. The earthquake had a magnitude of 7.2 ±0.3 on the surface wave magnitude scale. A tsunami and forty-five days of aftershocks followed the earthquake, over a thousand houses and 109 mosques were destroyed, and an estimated 10,000 people died. The Sea of Marmara is a basin formed at a releasing bend in the North Anatolian Fault. This local zone of extension occurs where this boundary between the Anatolian Plate and the Eurasian Plate steps northwards to the west of Izmit from the Izmit Fault to the Ganos Fault. The pattern of faults within the Sea of Marmara basin is complex, to the west, the fault trends west-east and is pure strike-slip in type. To the east, the fault is NW-SE trending and shows evidence of both normal and strike-slip motion, movement on this fault, which bounds the Çınarcık Basin, was the most likely cause of the 1509 event.
The area of significant damage extended from Çorlu in the west to Izmit in the east, galata and Büyükçekmece suffered severe damage. In Constantinople many houses collapsed, chimneys fell and walls cracked, the newly built Bayezid II Mosque was badly damaged, the main dome was destroyed and a minaret collapsed. The Fatih Mosque suffered damage to its four columns and the dome was split. The former church of Hagia Sophia survived almost unscathed, although a minaret collapsed, inside the mosque, the plaster that had been used to cover up the Byzantine mosaics inside the dome fell off, revealing the Christian images. The number of dead and injured is hard to estimate, with different sources giving accounts varying from 1,000 to 13,000 and it is believed that some members of the Ottoman dynasty died in this earthquake. Earthquake shocks continued for 45 days after the big earthquake, from the area and intensity of shaking, a 70 km fault rupture has been estimated. A tsunami is mentioned in sources with a run-up of greater than 6.0 m.
A turbidite bed whose deposition matches the date of the earthquake has been recognised in the Çınarcık Basin, List of earthquakes in Turkey List of historical earthquakes
Anatolia
Anatolia, in geography known as Asia Minor, Asian Turkey, Anatolian peninsula, or Anatolian plateau, is the westernmost protrusion of Asia, which makes up the majority of modern-day Turkey. The region is bounded by the Black Sea to the north, the Mediterranean Sea to the south, the Sea of Marmara forms a connection between the Black and Aegean Seas through the Bosphorus and Dardanelles straits and separates Anatolia from Thrace on the European mainland. Traditionally, Anatolia is considered to extend in the east to a line between the Gulf of Alexandretta and the Black Sea to the Armenian Highlands, traditionally Anatolia is the territory that comprises approximately the western two-thirds of the Asian part of Turkey. The Turkification of Anatolia began under the Seljuk Empire in the late 11th century, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Armenian, Laz and Greek. Traditionally, Anatolia is considered to extend in the east to a line running from the Gulf of Alexandretta to the Black Sea.
This traditional geographical definition is used, for example, in the latest edition of Merriam-Websters Geographical Dictionary, under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia. To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria, the first name the Greeks used for the Anatolian peninsula was Ἀσία, presumably after the name of the Assuwa league in western Anatolia. As the name of Asia came to be extended to areas east of the Mediterranean. The name Anatolia derives from the Greek ἀνατολή meaning “the East” or more literally “sunrise”, the precise reference of this term has varied over time, perhaps originally referring to the Aeolian and Dorian colonies on the west coast of Asia Minor. In the Byzantine Empire, the Anatolic Theme was a theme covering the western, the modern Turkish form of Anatolia is Anadolu, which again derives from the Greek name Aνατολή.
The Russian male name Anatoly and the French Anatole share the same linguistic origin, in English the name of Turkey for ancient Anatolia first appeared c. It is derived from the Medieval Latin Turchia, which was used by the Europeans to define the Seljuk controlled parts of Anatolia after the Battle of Manzikert. Human habitation in Anatolia dates back to the Paleolithic, neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the oldest branch of Indo-European, have spoken in Anatolia since at least the 19th century BC. The earliest historical records of Anatolia stem from the southeast of the region and are from the Mesopotamian-based Akkadian Empire during the reign of Sargon of Akkad in the 24th century BC, scholars generally believe the earliest indigenous populations of Anatolia were the Hattians and Hurrians. The region was famous for exporting raw materials, and areas of Hattian-, one of the numerous cuneiform records dated circa 20th century BC, found in Anatolia at the Assyrian colony of Kanesh, uses an advanced system of trading computations and credit lines.
They were speakers of an Indo-European language, the Hittite language, originating from Nesa, they conquered Hattusa in the 18th century BC, imposing themselves over Hattian- and Hurrian-speaking populations. According to the most widely accepted Kurgan theory on the Proto-Indo-European homeland, the Hittites adopted the cuneiform script, invented in Mesopotamia
Istanbul
Istanbul, historically known as Constantinople and Byzantium, is the most populous city in Turkey and the countrys economic and historic center. Istanbul is a city in Eurasia, straddling the Bosphorus strait between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives on the Asian side, the city is the administrative center of the Istanbul Metropolitan Municipality, both hosting a population of around 14.7 million residents. Istanbul is one of the worlds most populous cities and ranks as the worlds 7th-largest city proper, founded under the name of Byzantion on the Sarayburnu promontory around 660 BCE, the city developed to become one of the most significant in history. After its reestablishment as Constantinople in 330 CE, it served as a capital for almost 16 centuries, during the Roman and Byzantine, the Latin. Overlooked for the new capital Ankara during the period, the city has since regained much of its prominence.
The population of the city has increased tenfold since the 1950s, as migrants from across Anatolia have moved in, music and cultural festivals were established at the end of the 20th century and continue to be hosted by the city today. Infrastructure improvements have produced a complex transportation network, considered a global city, Istanbul has one of the fastest-growing metropolitan economies in the world. It hosts the headquarters of many Turkish companies and media outlets and accounts for more than a quarter of the gross domestic product. Hoping to capitalize on its revitalization and rapid expansion, Istanbul has bid for the Summer Olympics five times in twenty years, the first known name of the city is Byzantium, the name given to it at its foundation by Megarean colonists around 660 BCE. The name is thought to be derived from a personal name, ancient Greek tradition refers to a legendary king of that name as the leader of the Greek colonists. Modern scholars have hypothesized that the name of Byzas was of local Thracian or Illyrian origin.
He attempted to promote the name Nova Roma and its Greek version Νέα Ῥώμη Nea Romē, the use of Constantinople to refer to the city during the Ottoman period is now considered politically incorrect, even if not historically inaccurate, by Turks. By the 19th century, the city had acquired other names used by foreigners or Turks. Europeans used Constantinople to refer to the whole of the city, pera was used to describe the area between the Golden Horn and the Bosphorus, but Turks used the name Beyoğlu. The name İstanbul is commonly held to derive from the Medieval Greek phrase εἰς τὴν Πόλιν and this reflected its status as the only major city in the vicinity. The importance of Constantinople in the Ottoman world was reflected by its Ottoman name Der Saadet meaning the gate to Prosperity in Ottoman. An alternative view is that the name evolved directly from the name Constantinople, with the first, a Turkish folk etymology traces the name to Islam bol plenty of Islam because the city was called Islambol or Islambul as the capital of the Islamic Ottoman Empire
Fall of Constantinople
The Fall of Constantinople was the capture of the capital of the Byzantine Empire by an invading army of the Ottoman Empire on 29 May 1453. The Ottomans were commanded by the 21-year-old Mehmed the Conqueror, the sultan of the Ottoman Empire. The conquest of Constantinople followed a 53-day siege that had begun on 6 April 1453, the capture of Constantinople marked the end of the Roman Empire, an imperial state that had lasted for nearly 1,500 years. The Ottoman conquest of Constantinople dealt a blow to Christendom. After the conquest, Sultan Mehmed II transferred the capital of the Ottoman Empire from Edirne to Constantinople. The conquest of the city of Constantinople and the end of the Byzantine Empire was a key event in the Late Middle Ages, which marks, for some historians, Constantinople had been an imperial capital since its consecration in 330 under Roman Emperor, Constantine the Great. In the following centuries, the city had been besieged many times but was captured only once. The crusaders established an unstable Latin state in and around Constantinople while the remaining empire splintered into a number of Byzantine successor states, notably Nicaea and they fought as allies against the Latin establishments, but fought among themselves for the Byzantine throne.
The Nicaeans eventually reconquered Constantinople from the Latins in 1261, thereafter there was little peace for the much-weakened empire as it fended off successive attacks by the Latins, the Serbians, the Bulgarians, most importantly, the Ottoman Turks. The Black Plague between 1346 and 1349 killed almost half of the inhabitants of Constantinople, the Empire of Trebizond, an independent successor state that formed in the aftermath of the Fourth Crusade, survived on the coast of the Black Sea. This optimism was reinforced by friendly assurances made by Mehmed to envoys sent to his new court, but Mehmeds actions spoke far louder than his mild words. Since the mutual excommunications of 1054, the Pope in Rome was committed to establishing authority over the eastern church, nominal union had been negotiated in 1274, at the Second Council of Lyon, and indeed, some Palaiologoi emperors had since been received into the Latin church. Emperor John VIII Palaiologos had recently negotiated union with Pope Eugene IV, the attempted Union failed, greatly annoying Pope Nicholas V and the hierarchy of the Roman church.
Although some troops did arrive from the city states in the north of Italy. Some Western individuals, came to defend the city on their own account. One of these was a soldier from Genoa, Giovanni Giustiniani. A specialist in defending walled cities, he was given the overall command of the defense of the land walls by the emperor. In Venice, deliberations were taking place concerning the kind of assistance the Republic would lend to Constantinople
Byzantine Empire
It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, several signal events from the 4th to 6th centuries mark the period of transition during which the Roman Empires Greek East and Latin West divided. Constantine I reorganised the empire, made Constantinople the new capital, under Theodosius I, Christianity became the Empires official state religion and other religious practices were proscribed. Finally, under the reign of Heraclius, the Empires military, the borders of the Empire evolved significantly over its existence, as it went through several cycles of decline and recovery. During the reign of Maurice, the Empires eastern frontier was expanded, in a matter of years the Empire lost its richest provinces and Syria, to the Arabs. This battle opened the way for the Turks to settle in Anatolia, the Empire recovered again during the Komnenian restoration, such that by the 12th century Constantinople was the largest and wealthiest European city.
Despite the eventual recovery of Constantinople in 1261, the Byzantine Empire remained only one of several small states in the area for the final two centuries of its existence. Its remaining territories were annexed by the Ottomans over the 15th century. The Fall of Constantinople to the Ottoman Empire in 1453 finally ended the Byzantine Empire, the term comes from Byzantium, the name of the city of Constantinople before it became Constantines capital. This older name of the city would rarely be used from this point onward except in historical or poetic contexts. The publication in 1648 of the Byzantine du Louvre, and in 1680 of Du Canges Historia Byzantina further popularised the use of Byzantine among French authors, however, it was not until the mid-19th century that the term came into general use in the Western world. The Byzantine Empire was known to its inhabitants as the Roman Empire, the Empire of the Romans, the Roman Republic, and as Rhōmais. The inhabitants called themselves Romaioi and Graikoi, and even as late as the 19th century Greeks typically referred to modern Greek as Romaika and Graikika.
The authority of the Byzantine emperor as the legitimate Roman emperor was challenged by the coronation of Charlemagne as Imperator Augustus by Pope Leo III in the year 800. No such distinction existed in the Islamic and Slavic worlds, where the Empire was more seen as the continuation of the Roman Empire. In the Islamic world, the Roman Empire was known primarily as Rûm, the Roman army succeeded in conquering many territories covering the entire Mediterranean region and coastal regions in southwestern Europe and north Africa. These territories were home to different cultural groups, both urban populations and rural populations. The West suffered heavily from the instability of the 3rd century AD
Bayezid I
Bayezid I was the Ottoman Sultan from 1389 to 1402. He was the son of Murad I and Gülçiçek Hatun and he built one of the largest armies in the known world at the time and unsuccessfully besieged Constantinople. He was defeated and captured by Timur at the Battle of Ankara in 1402, the first major role of Bayezid was as governor of Kütahya, a city that was conquered from the Germiyanids. He was a soldier, earning the nickname of Lightning in a battle against the Karamanids. Immediately after obtaining the throne, he had his younger brother strangled to avoid a plot, in 1390, Bayezid took as a wife Princess Olivera Despina, the daughter of Prince Lazar of Serbia, who lost his life in Kosovo. Bayezid recognized Stefan Lazarević, the son of Lazar, as the new Serbian leader, the upper Serbia resisted the Ottomans until general Pashayigit captured the city of Skopje in 1391, converting the city to an important base of operations. Meanwhile, the sultan began unifying Anatolia under his rule, forcible expansion into Muslim territories could endanger the Ottoman relationship with the gazis, who were an important source of warriors for this ruling house on the European frontier.
So Bayezid began the practice to first secure fatwas, or legal rulings from Islamic scholars, however he suspected the loyalty of his Muslim Turkoman followers, for Bayezid relied heavily on his Serbian and Byzantine vassal troops to perform these conquests. In a single campaign over the summer and fall of 1390, Bayezid conquered the beyliks of Aydin and his major rival Sulayman, the emir of Karaman, responded by allying himself with the ruler of Sivas, Kadi Burhan al-Din and the remaining Turkish beyliks. At this point, Bayezid accepted peace proposals from Karaman, concerned that further advances would antagonize his Turkoman followers and lead them to ally with Kadi Burhan al-Din. Once peace had been made with Karaman, Bayezid moved north against Kastamonu which had given refuge to many fleeing from his forces, from 1389 to 1395 he conquered Bulgaria and northern Greece. In 1394 Bayezid crossed the River Danube to attack Wallachia, ruled at that time by Mircea the Elder, in 1394, Bayezid laid siege to Constantinople, the capital of the Byzantine Empire.
Anadoluhisarı fortress was built between 1393 and 1394 as part of preparations for the Second Ottoman Siege of Constantinople, which place in 1395. On the urgings of the Byzantine emperor Manuel II Palaeologus a new crusade was organized to defeat him and this proved unsuccessful, in 1396 the Christian allies, under the leadership of the King of Hungary and future Holy Roman Emperor Sigismund, were defeated in the Battle of Nicopolis. Bayezid built the magnificent Ulu Cami in Bursa, to celebrate this victory, thus the siege of Constantinople continued, lasting until 1402. The beleaguered Byzantines had their reprieve when Bayezid fought the Timurid Empire in the East, at this time, the empire of Bayezid included Thrace, Macedonia and parts of Serbia in Europe. In Asia, his domains extended to the Taurus Mountains and his army was considered one of the best in the Islamic world. In 1397, Bayezid defeated the emir of Karaman in Akçay, killing him, in 1398, the sultan conquered the Djanik emirate and the territory of Burhan al-Din, violating the accord with Timur
Feodosia
Feodosia, called Theodosia, is a port and resort, a town of regional significance in Crimea on the Black Sea coast. Feodosia serves as the center of Feodosia Municipality, one of the regions into which Crimea is divided. During much of its history the city was known as Caffa or Kaffa, the city was founded as Theodosia by Greek colonists from Miletos in the 6th century BC. Noted for its agricultural lands, on which its trade depended. Theodosia remained a village for much of the next nine hundred years. It was at times part of the sphere of influence of the Khazars, like the rest of Crimea, this place fell under the domination of the Kipchaks and was conquered by the Mongols in the 1230s. Between 1204–1261 and again in 1296–1307, the city of Kaffa was ruled by Genoas chief rival, in the late 13th century, traders from the Republic of Genoa arrived and purchased the city from the ruling Golden Horde. It came to one of Europes biggest slave markets. From 1266 and on, Kaffa was governed by a Genoese consul, in early 1318 Pope John XXII established a Latin Church diocese of Kaffa, as a suffragan of Genoa.
The first bishop was Fra Gerolamo, who had already been consecrated seven years before as a missionary bishop ad partes Tartarorum, the diocese ended as a residential bishopric with the capture of the city by the Ottomans in 1475. Accordingly, Kaffa is today listed by the Catholic Church as a titular see and it is believed that the devastating pandemic the Black Death entered Europe for the first time via Kaffa in 1347, through the movements of the Golden Horde. Fleeing inhabitants may have carried the back to Italy, causing its spread across Europe. However, the plague appears to have spread in a stepwise fashion, there were a number of Crimean ports under Mongol control, so it is unlikely that Kaffa was the only source of plague-infested ships heading to Europe. In addition, there were overland caravan routes from the East that would have been carrying the disease into Europe as well, the thriving, culturally diverse city and its thronged slave market have been described by the Spanish traveler Pedro Tafur, who was there in the 1430s.
In 1462 Caffa placed itself under the protection of King Casimir IV of Poland, Poland did not offer help when real danger came. Following the fall of Constantinople and lastly Trebizond and he was at no loss for a pretext to extinguish this last Genoese colony on the Black sea. In 1473, the tudun of the Crimean Khanate died and a fight developed over the appointment of his successor, the Genoese involved themselves in the dispute, and the Tatar notables who favored the losing candidate finally asked Mehmed to settle the dispute. Mehmed dispatched a fleet under the Ottoman commander Gedik Ahmet Pasha and it anchored before the walls of the city on 1 June, started the bombardment the next day, and on 6 June the inhabitants capitulated
Ottoman Empire
After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror, at the beginning of the 17th century the empire contained 32 provinces and numerous vassal states. Some of these were absorbed into the Ottoman Empire, while others were granted various types of autonomy during the course of centuries. With Constantinople as its capital and control of lands around the Mediterranean basin, while the empire was once thought to have entered a period of decline following the death of Suleiman the Magnificent, this view is no longer supported by the majority of academic historians. The empire continued to maintain a flexible and strong economy, however, during a long period of peace from 1740 to 1768, the Ottoman military system fell behind that of their European rivals, the Habsburg and Russian Empires. While the Empire was able to hold its own during the conflict, it was struggling with internal dissent.
Starting before World War I, but growing increasingly common and violent during it, major atrocities were committed by the Ottoman government against the Armenians and Pontic Greeks. The word Ottoman is an anglicisation of the name of Osman I. Osmans name in turn was the Turkish form of the Arabic name ʿUthmān, in Ottoman Turkish, the empire was referred to as Devlet-i ʿAlīye-yi ʿOsmānīye, or alternatively ʿOsmānlı Devleti. In Modern Turkish, it is known as Osmanlı İmparatorluğu or Osmanlı Devleti, the Turkish word for Ottoman originally referred to the tribal followers of Osman in the fourteenth century, and subsequently came to be used to refer to the empires military-administrative elite. In contrast, the term Turk was used to refer to the Anatolian peasant and tribal population, the term Rūmī was used to refer to Turkish-speakers by the other Muslim peoples of the empire and beyond. In Western Europe, the two names Ottoman Empire and Turkey were often used interchangeably, with Turkey being increasingly favored both in formal and informal situations and this dichotomy was officially ended in 1920–23, when the newly established Ankara-based Turkish government chose Turkey as the sole official name.
Most scholarly historians avoid the terms Turkey and Turkish when referring to the Ottomans, as the power of the Seljuk Sultanate of Rum declined in the 13th century, Anatolia was divided into a patchwork of independent Turkish principalities known as the Anatolian Beyliks. One of these beyliks, in the region of Bithynia on the frontier of the Byzantine Empire, was led by the Turkish tribal leader Osman, osmans early followers consisted both of Turkish tribal groups and Byzantine renegades, many but not all converts to Islam. Osman extended the control of his principality by conquering Byzantine towns along the Sakarya River and it is not well understood how the early Ottomans came to dominate their neighbours, due to the scarcity of the sources which survive from this period. One school of thought which was popular during the twentieth century argued that the Ottomans achieved success by rallying religious warriors to fight for them in the name of Islam, in the century after the death of Osman I, Ottoman rule began to extend over Anatolia and the Balkans.
Osmans son, captured the northwestern Anatolian city of Bursa in 1326 and this conquest meant the loss of Byzantine control over northwestern Anatolia. The important city of Thessaloniki was captured from the Venetians in 1387, the Ottoman victory at Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe
Mehmed the Conqueror
Mehmed II, commonly known as Mehmed the Conqueror, was an Ottoman sultan who ruled first for a short time from August 1444 to September 1446, and from February 1451 to May 1481. At the age of 21, he conquered Constantinople and brought an end to the Eastern Roman Empire, Mehmed continued his conquests in Anatolia with its reunification and in Southeast Europe as far west as Bosnia. Mehmed is considered a hero in modern-day Turkey and parts of the wider Muslim world, among other things, Istanbuls Fatih district, Fatih Sultan Mehmet Bridge and Fatih Mosque are named after him. Mehmed II was born on 30 March 1432, in Edirne and his father was Sultan Murad II and his mother Hüma Valide Hatun, born in the town of Devrekani, Kastamonu. When Mehmed II was eleven years old he was sent to Amasya to govern and thus gain experience, Sultan Murad II sent a number of teachers for him to study under. This Islamic education had an impact in molding Mehmeds mindset. He was influenced in his practice of Islamic epistemology by practitioners of science - particularly by his mentor, Molla Gürani -, after Murad II made peace with the Karamanids in Anatolia in August 1444, he abdicated the throne to his 12-year-old son Mehmed II.
In Mehmed IIs first reign, he defeated the crusade led by János Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged. Cardinal Julian Cesarini, the representative of the pope, had convinced the king of Hungary that breaking the truce with Muslims was not a betrayal, at this time Mehmed II asked his father Murad II to reclaim the throne, but Murad II refused. Angry at his father, who had long retired to a contemplative life in southwestern Anatolia, Mehmed II wrote, If you are the Sultan, come. If I am the Sultan I hereby order you to come and it was only after receiving this letter that Murad II led the Ottoman army and won the Battle of Varna in 1444. When Mehmed II ascended the throne again in 1451 he devoted himself to strengthening the Ottoman navy, having completed his fortresses, Mehmed proceeded to levy a toll on ships passing within reach of their cannon. Abu Ayyub al-Ansari, the companion and standard bearer of Muhammad, had died during the first Siege of Constantinople, as Mehmed IIs army approached Constantinople, Mehmeds sheikh Akshamsaddin discovered the tomb of Abu Ayyub al-Ansari.
After the conquest, Mehmed built Eyüp Sultan Mosque at the site to emphasize the importance of the conquest to the Islamic world, in early April, the Siege of Constantinople began. At first, the walls held off the Turks, even though Mehmeds army used the new bombard designed by Orban. The harbor of the Golden Horn was blocked by a boom chain, thus the Byzantines stretched their troops over a longer portion of the walls. About a month later, Constantinople fell, on 29 May, after this conquest, Mehmed moved the Ottoman capital from Adrianople to Constantinople. The contemporary scholar George of Trebizond supported his claim, the claim was recognized by the Eastern Orthodox Church, but not by the Catholic Church and most of, if not all, Western Europe
