The 4th century was the time period which lasted from 301 to 400. In the West, the early part of the century was shaped by Constantine the Great, who became the first Roman emperor to adopt Christianity. Gaining sole reign of the empire, he is noted for re-establishing a single imperial capital, choosing the site of ancient Byzantium in 330 to build the city soon called Nova Roma; the last emperor to control both the eastern and western halves of the empire was Theodosius I. As the century progressed after his death it became apparent that the empire had changed in many ways since the time of Augustus; the two emperor system established by Diocletian in the previous century fell into regular practice, the east continued to grow in importance as a centre of trade and imperial power, while Rome itself diminished in importance due to its location far from potential trouble spots, like Central Europe and the East. Late in the century Christianity became the official state religion, the empire's old pagan culture began to disappear.
General prosperity was felt throughout this period, but recurring invasions by Germanic tribes plagued the empire from AD 376 onward. These early invasions marked the beginning of the end for the Western Roman Empire. In China, the Jin dynasty, which had united the nation prior in 280, began to face troubles by the start of the century due to political infighting, which led to the opportunistic insurrections of the northern barbarian tribes, which overwhelmed the empire, forcing the Jin court to retreat and entrench itself in the south past the Yangtze river, starting what is known as the Eastern Jin dynasty around 317. Towards the end of the century, Emperor of the Former Qin, Fu Jiān, united the north under his banner, planned to conquer the Jin dynasty in the south, so as to reunite the land, but was decisively defeated at the Battle of Fei River in 383, causing massive unrest and civil war in his empire, thereby leading to the fall of the Former Qin, the continued existence of the Eastern Jin dynasty.
According to archaeologists, sufficient archaeological correlates of state-level societies coalesced in the 4th century to show the existence in Korea of the Three Kingdoms of Baekje and Silla. Historians of the Roman Empire may refer to the "Long Fourth Century", the period spanning the fourth century proper, but starting earlier with the accession of the emperor Diocletian in 284 and ending with the death of Honorius in 423 or of Theodosius II in 450.

The Zapotec civilization was an indigenous pre-Columbian civilization that flourished in the Valley of Oaxaca in Mesoamerica. Archaeological evidence shows; the Zapotec left archaeological evidence at the ancient city of Monte Albán in the form of buildings, ball courts, magnificent tombs and grave goods including finely worked gold jewelry. Monte Albán was one of the first major cities in Mesoamerica and the center of a Zapotec state that dominated much of the territory that today belongs to the Mexican state of Oaxaca. Zapotec civilization originated in the Central Valleys of Oaxaca in the late 6th Century BC; the three valleys were divided between three different-sized societies, separated by 80 square kilometres “no-man’s-land” in the middle, today occupied by the city of Oaxaca. Archaeological evidence, such as burned temples and sacrificed captives, suggests that the three societies competed against each other. At the end of the Rosario phase, the valley's largest settlement San José Mogote, a nearby settlement in the Etla valley, lost most of their population.
During the same period, a new large settlement emerged in the “no-man’s-land” on top of a mountain overlooking the three valleys, called Monte Albán. Early Monte Albán pottery is similar to pottery from San José Mogote, which suggests that Monte Albán was populated by the people who left San José Mogote. Although there is no direct evidence in the early phases of Monte Albán's history and fortifications around the site during the archaeological phase Monte Alban 2 suggest that the city was constructed in response to a military threat. Archaeologists Joyce Marcus and Kent V. Flannery liken this process to what happened in ancient Greece -: a centralization of smaller dispersed populations congregated in a central city to meet an external threat; the Zapotec state formed at Monte Albán began to expand during the late Monte Alban 1 phase and throughout the Monte Alban 2 phase. During Monte Alban 1c to Monte Alban 2, Zapotec rulers seized control of the provinces outside the valley of Oaxaca because none of the surrounding provinces could compete with the valley of Oaxaca politically and militarily.
By 200 AD, the Zapotecs had extended their influence, from Quiotepec in the North to Ocelotepec and Chiltepec in the South. Monte Albán had become the largest city in what are today the southern Mexican highlands, retained this status until 700 AD; the expansion of the Zapotec empire peaked during the Monte Alban 2 phase. Zapotecs colonized settlements far beyond The Valley of Oaxaca. Most notably, this expansion is visible in the sudden change of ceramics found in regions outside the valley; these region's own unique styles were replaced with Zapotec style pottery, indicating their integration into the Zapotec empire. Archaeologist Alfonso Caso, one of the first to do excavations in Monte Albán, argued that a building on the main plaza of Monte Albán is further evidence for the dramatic expansion of the Zapotec state. What today is called Building J is shaped like an arrowhead and displays more than 40 carved stones with hieroglyphic writing. Archaeologists interpreted the glyphs to represent the provinces controlled by the Zapotecs.
Each glyph group depicts a head with an elaborate head dress carved into the slabs. These are assumed to illustrate the rulers of the provinces. Heads turned upside down are believed to represent the rulers of those provinces taken by force, while the upright ones may represent those who did not resist colonization and had their lives spared. For this reason, Building J is called “The Conquest Slab”. Marcus and Flannery write about the subsequent dramatic expansion of the Monte Albán state: "a great disparity in populations between the core of a state and its periphery, it may only be necessary for the former to send colonists to the latter. Small polities, may accept a face-saving offer. Larger polities unwilling to lose their autonomy may have to be subdued militarily. During the expansion of Monte Alban 2 state, we think we see both colonization and conquest"; the name Zapotec is an exonym coming from Nahuatl tzapotēcah, which means "inhabitants of the place of sapote". The Zapotec referred to themselves by some variant of the term Be'ena'a, which means "The Cloud People".
The Zapotec languages belong to a language family called Oto-manguean, an ancient family of Mesoamerican languages. It is estimated that today's Oto-manguean languages branched off from a common root at around 1500 BC; the Manguean languages split off first, followed by the Oto-pamean branch while the divergence of Mixtecan and Zapotecan languages happened still. The Zapotecan group includes the Zapotec languages and the related Chatino. Zapotec languages are spoken in parts of the Northern Sierra, the Central Valleys as well as in parts of the Southern Sierra, in the Isthmus of Tehuantepec and along parts of the Pacific Coast. Due to decades of out-migration, Zapotec is spoken in parts of Mexico City and Los Angeles, CA. There are over 100 dialects. Zapotec is a tone language, which means that the meaning of a word is determined by voice pitch, essential for understanding the meaning of different words; the Zapotec languages features up to 4 distinct tonemes: high, low and falling. Between Monte Alban phases 1 and 2 there was a considerable expansion of the population of the Valley of Oaxaca.
As the population grew, so did the degree of social differentiation, the centralization of political power
The Danube is Europe's second longest river, after the Volga. It is located in Eastern Europe; the Danube was once a long-standing frontier of the Roman Empire, today flows through 10 countries, more than any other river in the world. Originating in Germany, the Danube flows southeast for 2,850 km, passing through or bordering Austria, Hungary, Serbia, Bulgaria and Ukraine before draining into the Black Sea, its drainage basin extends into nine more countries. The Danube river basin is home to fish species such as pike, huchen, Wels catfish and tench, it is home to a large diversity of carp and sturgeon, as well as salmon and trout. A few species of euryhaline fish, such as European seabass and eel, inhabit the Danube Delta and the lower portion of the river. Since ancient times, the Danube has become a traditional trade route in Europe, nowadays 2,415 km of its total length being navigable; the river is an important source of energy and drinking water. Danube is an Old European river name derived from a Proto-Indo-European *dānu.
Other river names from the same root include the Dunaj, Dzvina/Daugava, Donets, Dniestr, Dysna and Tuoni. In Rigvedic Sanskrit, dānu means "fluid, drop", in Avestan, the same word means "river". In the Rigveda, Dānu once appears as the mother of Vrtra, "a dragon blocking the course of the rivers"; the Finnish word for Danube is Tonava, most derived from the word for the river in Swedish and German, Donau. Its Sámi name Deatnu means "Great River", it is possible that dānu in Scythian as in Avestan was a generic word for "river": Dnieper and Dniestr, from Danapris and Danastius, are presumed to continue Scythian *dānu apara "far river" and *dānu nazdya- "near river", respectively. The river was known to the ancient Greeks as the Istros a borrowing from a Daco-Thracian name meaning "strong, swift", from a root also encountered in the ancient name of the Dniester and akin to Iranic turos “swift” and Sanskrit iṣiras "swift", from the PIE *isro-, *sreu “to flow”. In the Middle Ages, the Greek Tiras was borrowed into Italian as Tyrlo and into Turkic languages as Tyrla, the latter further borrowed into Romanian as a regionalism.
The Thraco-Phrygian name was Matoas, "the bringer of luck". In Latin, the Danube was variously known as Ister; the Latin name is masculine, except Slovenian. The German Donau is feminine, as it has been re-interpreted as containing the suffix -ouwe "wetland". Romanian differs from other surrounding languages in designating the river with a feminine term, Dunărea; this form was not inherited from Latin. To explain the loss of the Latin name, scholars who suppose that Romanian developed near the large river propose that the Romanian name descends from a hypotetical Thracian *Donaris that shares the same PIE root with the Iranic don-/dan-, with the suffix -aris encountered in the ancient name of the Ialomița River, in the unidentified Miliare river mentioned by Jordanes in his Getica. Gábor Vékony says that this hypothesis is not plausible, because the Greeks borrowed the Istros form from the native Thracians, he proposes. The modern languages spoken in the Danube basin all use names related to Dānuvius: German: Donau.
Dunav. Dunai. Classified as an international waterway, it originates in the town of Donaueschingen, in the Black Forest of Germany, at the confluence of the rivers Brigach and Breg; the Danube flows southeast for about 2,730 km, passing through four capital cities before emptying into the Black Sea via the Danube Delta in Romania and Ukraine. Once a long-standing frontier of the Roman Empire, the river passes through or touches the borders of 10 countries: Romania, Serbia, Germany, Slovakia, Croatia and Moldova, its drainage basin extends into nine more. In addition to the bordering countries, the drainage basin includes parts of nine more countries: Bosnia and Herzegovina, the Czech Republic, Montenegro, Italy, North Macedonia and Albania, its total drainage basin is 801,463 km2. The highest point of the drainage basin is the summit of Piz Bernina at the Italy–Switzerland border, at 4,049 metres; the land drained by the Danube extends into many other countries. Many Danubian tributaries are important rivers in their own right, navigable by barges and other shallow-draught boats.
From its source to its outlet into the Black Sea, its main tribu
Christians are people who follow or adhere to Christianity, a monotheistic Abrahamic religion based on the life and teachings of Jesus Christ. The words Christ and Christian derive from the Koine Greek title Christós, a translation of the Biblical Hebrew term mashiach. While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance; the term "Christian" is used as an adjective to describe anything associated with Christianity, or in a proverbial sense "all, noble, good, Christ-like."According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. By 2050, the Christian population is expected to exceed 3 billion. According to a 2012 Pew Research Center survey Christianity will remain the world's largest religion in 2050, if current trends continue. Today, about 37% of all Christians live in the Americas, about 26% live in Europe, 24% live in sub-Saharan Africa, about 13% live in Asia and the Pacific, 1% live in the Middle East and North Africa.
About half of all Christians worldwide are Catholic. Orthodox communions comprise 12% of the world's Christians. Other Christian groups make up the remainder. Christians make up the majority of the population in territories. 280 million Christians live as a minority. Christians have made noted contributions to a range of fields, including the sciences, politics and business. According to 100 Years of Nobel Prizes, a review of Nobel prizes awarded between 1901 and 2000 reveals that of Nobel Prizes laureates identified Christianity in its various forms as their religious preference; the Greek word Χριστιανός, meaning "follower of Christ", comes from Χριστός, meaning "anointed one", with an adjectival ending borrowed from Latin to denote adhering to, or belonging to, as in slave ownership. In the Greek Septuagint, christos was used to translate the Hebrew מָשִׁיחַ, meaning " anointed." In other European languages, equivalent words to Christian are derived from the Greek, such as Chrétien in French and Cristiano in Spanish.
The abbreviations Xian and Xtian have been used since at least the 17th century: Oxford English Dictionary shows a 1634 use of Xtianity and Xian is seen in a 1634-38 diary. The word Xmas uses a similar contraction; the first recorded use of the term is in the New Testament, in Acts 11:26, after Barnabas brought Saul to Antioch where they taught the disciples for about a year, the text says: " the disciples were called Christians first in Antioch." The second mention of the term follows in Acts 26:28, where Herod Agrippa II replied to Paul the Apostle, "Then Agrippa said unto Paul, Almost thou persuadest me to be a Christian." The third and final New Testament reference to the term is in 1 Peter 4:16, which exhorts believers: "Yet if as a Christian, let him not be ashamed. The city of Antioch, where someone gave them the name Christians, had a reputation for coming up with such nicknames; however Peter's apparent endorsement of the term led to its being preferred over "Nazarenes" and the term Christianoi from 1 Peter becomes the standard term in the Early Church Fathers from Ignatius and Polycarp onwards.
The earliest occurrences of the term in non-Christian literature include Josephus, referring to "the tribe of Christians, so named from him. In the Annals he relates that "by vulgar appellation called Christians" and identifies Christians as Nero's scapegoats for the Great Fire of Rome. Another term for Christians which appears in the New Testament is "Nazarenes". Jesus is named as a Nazarene in Math 2:23, while Saul-Paul is said to be Nazarene in Acts 24:5; the latter verse makes it clear that Nazarene referred to the name of a sect or heresy, as well as the town called Nazareth. The term Nazarene was used by the Jewish lawyer Tertullus which records that "the Jews call us Nazarenes." While around 331 AD Eusebius records that Christ was called a Nazoraean from the name Nazareth, that in earlier centuries "Christians" were once called "Nazarenes". The Hebrew equivalent of "Nazarenes", occurs in the Babylonian Talmud, is still the modern Israeli Hebrew term for Christian. A wide range of beliefs and practices are found across the world among those who call themselves Christian.
Denominations and sects disagree on a common definition of "Christianity". For example, Timothy Beal notes the disparity of beliefs among those who identify as Christians in the United States as follows: Although all of them have their historical roots in Christian theology and tradition, although most would identify themselves as Christian, many would not identify others within the larger category as Christian. Most Baptists and fundamentalists, for example, would not acknowledge Mormonism or Christian Science as Christian. In fact, the nearly 77 percent of Americans who self-identify as Christian are a diverse pluribus of Christianities that are far from any collective unity. Linda Woodhead attempts to provide a common belief thread for Christians by noting that "Whatever else they might disagree about, Christians are at least united
The Roman Empire was the post-Roman Republic period of the ancient Roman civilization. Ruled by emperors, it had large territorial holdings around the Mediterranean Sea in Europe, North Africa, the Middle East, the Caucasus. From the constitutional reforms of Augustus to the military anarchy of the third century, the Empire was a principate ruled from the city of Rome; the Roman Empire was ruled by multiple emperors and divided in a Western Roman Empire, based in Milan and Ravenna, an Eastern Roman Empire, based in Nicomedia and Constantinople. Rome remained the nominal capital of both parts until 476 AD, when Odoacer deposed Romulus Augustus after capturing Ravenna and the Roman Senate sent the imperial regalia to Constantinople; the fall of the Western Roman Empire to barbarian kings, along with the hellenization of the Eastern Roman Empire into the Byzantine Empire, is conventionally used to mark the end of Ancient Rome and the beginning of the Middle Ages. The previous Republic, which had replaced Rome's monarchy in the 6th century BC, became destabilized in a series of civil wars and political conflict.
In the mid-1st century BC Julius Caesar was appointed as perpetual dictator and assassinated in 44 BC. Civil wars and proscriptions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC; the following year Octavian conquered Ptolemaic Egypt, ending the Hellenistic period that had begun with the conquests of Alexander the Great of Macedon in the 4th century BC. Octavian's power was unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title Augustus making him the first emperor; the first two centuries of the Empire were a period of unprecedented stability and prosperity known as the Pax Romana. It reached its greatest territorial expanse during the reign of Trajan. A period of increasing trouble and decline began with the reign of Commodus. In the 3rd century, the Empire underwent a crisis that threatened its existence, but was reunified under Aurelian. In an effort to stabilize the Empire, Diocletian set up two different imperial courts in the Greek East and Latin West.
Christians rose to power in the 4th century following the Edict of Milan in 313 and the Edict of Thessalonica in 380. Shortly after, the Migration Period involving large invasions by Germanic peoples and the Huns of Attila led to the decline of the Western Roman Empire. With the fall of Ravenna to the Germanic Herulians and the deposition of Romulus Augustulus in 476 AD by Odoacer, the Western Roman Empire collapsed and it was formally abolished by emperor Zeno in 480 AD; the Eastern Roman Empire, known in the post-Roman West as the Byzantine Empire, collapsed when Constantinople fell to the Ottoman Turks of Mehmed II in 1453. Due to the Roman Empire's vast extent and long endurance, the institutions and culture of Rome had a profound and lasting influence on the development of language, architecture, philosophy and forms of government in the territory it governed Europe; the Latin language of the Romans evolved into the Romance languages of the medieval and modern world, while Medieval Greek became the language of the Eastern Roman Empire.
Its adoption of Christianity led to the formation of Christendom during the Middle Ages. Greek and Roman art had a profound impact on the late medieval Italian Renaissance, while Rome's republican institutions influenced the political development of republics such as the United States and France; the corpus of Roman law has its descendants in many legal systems of the world today, such as the Napoleonic Code. Rome's architectural tradition served as the basis for Neoclassical architecture. Rome had begun expanding shortly after the founding of the republic in the 6th century BC, though it did not expand outside the Italian peninsula until the 3rd century BC, it was an "empire" long before it had an emperor. The Roman Republic was not a nation-state in the modern sense, but a network of towns left to rule themselves and provinces administered by military commanders, it was ruled, not by annually elected magistrates in conjunction with the senate. For various reasons, the 1st century BC was a time of political and military upheaval, which led to rule by emperors.
The consuls' military power rested in the Roman legal concept of imperium, which means "command". Successful consuls were given the honorary title imperator, this is the origin of the word emperor since this title was always bestowed to the early emperors upon their accession. Rome suffered a long series of internal conflicts and civil wars from the late second century BC onward, while extending its power beyond Italy; this was the period of the Crisis of the Roman Republic. Towards the end of this era, in 44 BC, Julius Caesar was perpetual dictator before being assassinated; the faction of his assassins was driven from Rome and defeated at the Battle of Philippi in 42 BC by an army led by Mark Antony and Caesar's adopted son Octavian. Antony and Octavian's division of the Roman world between themselves did not last and Octavian's forces defeated those of Mark Antony and Cleopatra at the Battle of Actium in 31 BC, ending the Final War of the Roman Republic. In 27 BC the Senate and People of Rome made Octavian princeps ("first citi
Moesia was an ancient region and Roman province situated in the Balkans south of the Danube River. It included most of the territory of modern-day Central Serbia and the northern parts of the modern North Macedonia, Northern Bulgaria and Romanian Dobrudja. In ancient geographical sources, Moesia was bounded to the south by the Haemus and Scardus mountains, to the west by the Drinus river, on the north by the Donaris and on the east by the Euxine; the region was inhabited chiefly by Thracians, Dacians and Thraco-Illyrian peoples. The name of the region comes from Moesi, Thraco-Dacian peoples who lived there before the Roman conquest. Parts of Moesia belonged to the polity of Burebista, a Getae king who established his rule over a large part of the northern Balkans between 82 BC and 44 BC, he led plunder and conquest raids across Central and Southeastern Europe, subjugating most of the neighbouring tribes. After his assassination in an inside plot, the empire was divided into several smaller states.
In 75 BC, C. Scribonius Curio, proconsul of Macedonia, took an army as far as the Danube and gained a victory over the inhabitants, who were subdued by M. Licinius Crassus, grandson of the triumvir and also proconsul of Macedonia during the reign of Augustus c. 29 BC. The region, was not organized as a province until the last years of Augustus' reign; as a province, Moesia was under an imperial consular legate. In 86 AD the Dacian king Duras ordered his troops to attack Roman Moesia. After this attack, the Roman emperor Domitian arrived in Moesia and reorganized it in 87 AD into two provinces, divided by the river Cebrus: to the west Moesia Superior - Upper Moesia, to the east Moesia Inferior - Lower Moesia; each was governed by a procurator. The chief towns of Upper Moesia in the Principate were: Singidunum, Remesiana, Bononia and Skupi; the last two were Greek towns which formed a pentapolis with Istros and Apollonia. From Moesia, Domitian began planning future campaigns into Dacia and by 87 he started a strong offensive against Dacia, ordering General Cornelius Fuscus to attack.
Therefore, in the summer of 87, Fuscus led six legions across the Danube. The campaign against the Dacians ended without a decisive outcome, Decebalus, the Dacian King, had brazenly flouted the terms of the peace, agreed on at the war's end. Emperor Trajan arrived in Moesia, he launched his first military campaign into the Dacian Kingdom c. March–May 101, crossing to the northern bank of the Danube River and defeating the Dacian army near Tapae, a mountain pass in the Carpathians. Trajan's troops were mauled in the encounter, he put off further campaigning for the year to heal troops and regroup. During the following winter, King Decebalus launched a counter-attack across the Danube further downstream, but this was repulsed. Trajan's army advanced further into Dacian territory and forced King Decebalus to submit to him a year later. Trajan was granted the title Dacicus; the victory was celebrated by the Tropaeum Traiani. However, Decebalus in 105 undertook an invasion against Roman territory by attempting to stir up some of the tribes north of the river against the empire.
Trajan took to the field again and after building with the design of Apollodorus of Damascus his massive bridge over the Danube, he conquered part of Dacia in 106. Sometime around 272, at the Moesian city of Naissus or Nissa, future emperor Constantine. After the abandonment of Roman Dacia to the Goths by Aurelian and the transfer of the Roman citizens from the former province to the south of the Danube, the central portion of Moesia took the name of Dacia Aureliana. During administrative reforms of Emperor Diocletian, both of the Moesian provinces were reorganized. Moesia Superior was divided in two, northern part forming the province of Moesia Prima including cities Viminacium and Singidunum, while the southern part was organised as the new province of Dardania with cities Scupi and Ulpiana. At the same time, Moesia Inferior was divided into Scythia Minor. Moesia Secunda's main cities included Marcianopolis, Nicopolis, Durostorum, Sexaginta Prista and Novae, all in Bulgaria today; as a frontier province, Moesia was strengthened by stations and fortresses erected along the southern bank of the Danube, a wall was built from Axiopolis to Tomi as a protection against the Scythians and Sarmatians.
The garrison of Moesia Secunda included Legio I Italica and Legio XI Claudia, as well as independent infantry units, cavalry units, river flotillas. The Notitia Dignitatum lists its units and their bases as of the 390s CE. Units in Scythia Minor included Legio I Iov
Mesoamerica is a historical region and cultural area in North America. It extends from central Mexico through Belize, Guatemala, El Salvador, Honduras and northern Costa Rica, within this region pre-Columbian societies flourished before the Spanish colonization of the Americas. In the 16th century, European diseases like smallpox and measles caused the deaths of upwards of 90% of the indigenous people, it is one of five areas in the world where ancient civilization arose independently, the second in the Americas along with Norte Chico in present-day Peru, in the northern coastal region. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures. Beginning as early as 7000 BCE, the domestication of cacao, beans, avocado, vanilla and chili, as well as the turkey and dog, caused a transition from paleo-Indian hunter-gatherer tribal grouping to the organization of sedentary agricultural villages. In the subsequent Formative period and cultural traits such as a complex mythological and religious tradition, a vigesimal numeric system, a complex calendric system, a tradition of ball playing, a distinct architectural style, were diffused through the area.
In this period, villages began to become stratified and develop into chiefdoms with the development of large ceremonial centers, interconnected by a network of trade routes for the exchange of luxury goods, such as obsidian, cacao, Spondylus shells and ceramics. While Mesoamerican civilization did know of the wheel and basic metallurgy, neither of these technologies became culturally important. Among the earliest complex civilizations was the Olmec culture, which inhabited the Gulf Coast of Mexico and extended inland and southwards across the Isthmus of Tehuantepec. Frequent contact and cultural interchange between the early Olmec and other cultures in Chiapas and Oaxaca laid the basis for the Mesoamerican cultural area. All this was facilitated by considerable regional communications in ancient Mesoamerica along the Pacific coast; this formative period saw the spread of distinct religious and symbolic traditions, as well as artistic and architectural complexes. In the subsequent Preclassic period, complex urban polities began to develop among the Maya, with the rise of centers such as El Mirador and Tikal, the Zapotec at Monte Albán.
During this period, the first true Mesoamerican writing systems were developed in the Epi-Olmec and the Zapotec cultures, the Mesoamerican writing tradition reached its height in the Classic Maya hieroglyphic script. Mesoamerica is one of only three regions of the world where writing is known to have independently developed. In Central Mexico, the height of the Classic period saw the ascendancy of the city of Teotihuacan, which formed a military and commercial empire whose political influence stretched south into the Maya area and northward. Upon the collapse of Teotihuacán around 600 AD, competition between several important political centers in central Mexico, such as Xochicalco and Cholula, ensued. At this time during the Epi-Classic period, the Nahua peoples began moving south into Mesoamerica from the North, became politically and culturally dominant in central Mexico, as they displaced speakers of Oto-Manguean languages. During the early post-Classic period, Central Mexico was dominated by the Toltec culture, Oaxaca by the Mixtec, the lowland Maya area had important centers at Chichén Itzá and Mayapán.
Towards the end of the post-Classic period, the Aztecs of Central Mexico built a tributary empire covering most of central Mesoamerica. The distinct Mesoamerican cultural tradition ended with the Spanish conquest in the 16th century. Over the next centuries, Mesoamerican indigenous cultures were subjected to Spanish colonial rule. Aspects of the Mesoamerican cultural heritage still survive among the indigenous peoples who inhabit Mesoamerica, many of whom continue to speak their ancestral languages, maintain many practices harking back to their Mesoamerican roots; the term Mesoamerica means "middle America" in Greek. Middle America refers to a larger area in the Americas, but it has previously been used more narrowly to refer to Mesoamerica. An example is the title of the 16 volumes of The Handbook of Middle American Indians. "Mesoamerica" is broadly defined as the area, home to the Mesoamerican civilization, which comprises a group of peoples with close cultural and historical ties. The exact geographic extent of Mesoamerica has varied through time, as the civilization extended North and South from its heartland in southern Mexico.
The term was first used by the German ethnologist Paul Kirchhoff, who noted that similarities existed among the various pre-Columbian cultures within the region that included southern Mexico, Belize, El Salvador, western Honduras, the Pacific lowlands of Nicaragua and northwestern Costa Rica. In the tradition of cultural history, the prevalent archaeological theory of the early to middle 20th century, Kirchhoff defined this zone as a cultural area based on a suite of interrelated cultural similarities brought about by millennia of inter- and intra-regional interaction. Mesoamerica is recognized as a near-prototypical cultural area, the term is now integrated in the standard terminology of pre-Columbian anthropological studies.
