Assyrians (Syriac: ܣܘܪ̈ܝܐ, romanized: Sūrāyē / Sūrōyē) are a distinct ethnic group native to Mesopotamia with roots in ancient Assyria. They speak varieties of Neo-Aramaic, a branch of the Semitic language family, and largely adhere to Syriac Christianity. The Assyrian homeland lies in northern Mesopotamia, encompassing areas along the Zab rivers and spanning parts of modern Turkey, Iran, Iraq, and Syria. Large-scale displacement has led to a diaspora across North America, Europe, Australia, the Middle East, and the Caucasus, fueled by genocide, persecution, and regional conflicts. In the United States, Assyrians have preserved and adapted their cultural identity, with notable communities in the Midwest and California. Some members of the community identify alternatively as Chaldeans or Arameans, based on religious, regional, and historic traditions.
Assyrians have a continuous cultural and linguistic presence spanning over three millennia. Originally speaking Akkadian, they adopted Aramaic which became a regional lingua franca spoken by Jesus of Nazareth that influenced Hebrew and Arabic. Today, they speak modern Neo-Aramaic dialects with Akkadian roots (primarily Suret and Turoyo) and primarily practice Syriac Christianity across two rites. These include the Chaldean Catholic Church, Assyrian Church of the East, and the Ancient Church of the East in the East Syriac Rite, and the Syriac Catholic and Syriac Orthodox churches in the West Syriac Rite. Aramaic remains one of the oldest continuously used languages in West Asia.
They were among the earliest peoples to adopt Christianity, traditionally tracing its introduction to the 1st century AD through the missionary work of St. Thomas the Apostle and his disciples, St. Addai and St. Mari. The Assyrians established the Church of the East and the distinct East Syriac Rite, playing a central role in spreading Christianity across Asia. They are broadly distinguished into three principal ecclesiastical traditions, divided by liturgy, dialect, theology, and historical development. Shared historical experiences, including early Christianisation and episodes of persecution, have fostered close ties with neighbouring Armenians.
Linguistically, the name Assyria is rooted in East Semitic nomenclature. Biblical traditions connect the name to Ashur, the son of Shem in the Book of Genesis, who was traditionally regarded as the eponymous patriarch of the Assyrian nation. The earliest attestations trace back to the early 3rd millennium BC, originating from the ancient city-state and capital of Assur (Akkadian: 𒀸𒋩𒆠, Aššūr). In international statecraft and neighboring languages, the designation evolved phonetically: in Old Persian inscriptions such as the Behistun Inscription, it is recorded as Aššura or Āthur, while in Babylonian and Elamite contexts it appeared as Aššuru and Aššura. Ancient Greek historians and geographers later Hellenized the term as Assyria (Ἀσσυρία), a convention subsequently adopted into Latin and modern European languages.
Modern Assyrians refer to themselves primarily as Āṯōrāyē (ܐܬܘܪ̈ܝܐ) or Sūrāyē/Suroye (ܣܘܪ̈ܝܐ), a variant of Classical Syriac. This ethnonym is closely linked to the self-designations of Aramaic-speaking Christians in Mesopotamia. During the late antiquity period, these communities adopted the term Sūryoyo, an Aramaic adaptation of the Greek Súrios. This term gradually replaced the older Aramaic autonym Armāyā ("Aramean") in literary, liturgical, and vernacular contexts, though both names continued to be used side by side well into the medieval period.
Assyria is the homeland of the Assyrian people, located in the ancient Near East. The earliest Neolithic sites in Assyria belonged to the Jarmo culture c. 7100 BC and Tell Hassuna, the centre of the Hassuna culture, c. 6000 BC.
The history of Assyria begins with the formation of the city of Assur, perhaps as early as the 25th century BC. Although the Assyrians were part of the Akkadian-speaking Semitic peoples of Mesopotamia, the Hurrians may also have played an important role in the origins and civilization of the Assyrians. Ephraim A. Speiser for instance, wrote that the influence of the Hurrians upon Assyria was more fundamental and far-reaching than is ordinarily implied, and they entered prominently into the "make-up" of the later Assyrians.
During the early Bronze Age period, Sargon of Akkad united all the native Semitic-speaking peoples, including the Assyrians, and the Sumerians of Mesopotamia under the Akkadian Empire (2335–2154 BC). At this time, the city of Assur already existed and would later become the heart of the Assyrian Empire.
Under Sennacherib, Nineveh became Assyria's capital and was extensively expanded, covering about 750 hectares—more than twice the size of Calah or Dur-Sharrukin—and emerging as the largest and potentially wealthiest city of the ancient world. Some scholars suggest that the famed Hanging Gardens, often attributed to Babylon, may in fact have been located in Nineveh.
Prior to the rise of Nineveh, the Assyrian city of Nimrud (ancient Kalhu) emerged as the largest urban center in the world by around 800 BC. The city was established as the royal seat and military capital by Ashurnasirpal II, whose extensive building programs on the Acropolis and outer town significantly expanded Kalhu and enhanced its political and cultural significance in the Neo-Assyrian Empire.
In their early stages, Assyrian cities such as Assur and Nineveh appear to have functioned as administrative centers under Sumerian control rather than as independent political entities. Over time, the Sumerian population was gradually absorbed into the broader Akkadian-speaking (Assyro-Babylonian) populace. An Assyrian identity distinct from other neighboring groups appears to have formed during the Old Assyrian period, in the 21st or 20th century BC.
In the traditions of the Assyrian Church of the East, they are descended from Abraham's grandson, Dedan son of Jokshan, progenitor of the ancient Assyrians. However, there is no other historical basis for this assertion. The Hebrew Bible does not directly mention it, and there is no mention in Assyrian records, which date as far back as the 25th century BC. What is known is that Ashur-uballit I overthrew the Mitanni c. 1365 BC and the Assyrians benefited from this development by taking control of the eastern portion of Mitanni territory and later annexing Hittite, Babylonian, Amorite and Hurrian territories. The rise and rule of the Middle Assyrian Empire (14th to 10th century BC) spread Assyrian culture, people and identity across northern Mesopotamia.
By the late eighth century BC, Assyria had become the largest and most formidable empire yet established, with the most powerful army assembled up to that time and pioneering military techniques—including cavalry and advanced siege equipment—that influenced warfare for more than two millennia. Its success relied not only on military strength but also on a highly efficient bureaucracy and a vast administrative and trade network stretching from the Persian Gulf to Egypt.
The excessive expansion of the Assyrian Empire, combined with internal conflict during the reign of Ashurbanipal and the widespread resentment provoked by its oppressive rule, significantly undermined the state's stability and strength. The Babylonians and Medes formed an alliance and captured Nineveh in 612 BC. After a final defeat at Harran in 609 BC, the empire fell. Despite this, Assyria's culture and administrative practices influenced the subsequent Babylonian and Persian empires.
The Assyrian people, after the fall of the Neo-Assyrian Empire in 609 BC, were under the control of the Neo-Babylonian Empire and later, the Persian Empire, which consumed the entire Neo-Babylonian or "Chaldean" Empire in 539 BC. Assyrians became front line soldiers for the Persian Empire under Xerxes I, playing a significant role in the Battle of Marathon under Darius I in 490 BC. However, Herodotus, whose Histories are the primary source of information about that battle, makes no mention of Assyrians in connection with it.
