Christians in Iraq are one of the oldest, continuous and significant Christian communities. The vast majority of Iraqi Christians are indigenous Assyrians who descend from the ancient Assyria, followed by Armenians and Arab Christians, and a very small minority of Kurdish, Shabaks and Iraqi Turkmen Christians. Christians in Iraq primarily adhere to the Syriac Christian tradition and rites and speak Northeastern Neo-Aramaic dialects, although Turoyo is also present on a smaller scale. Some are also known by the name of their religious denomination as well as their ethnic identity, such as Chaldean Catholics, Chaldo-Assyrians, or Syriacs. Regardless of religious affiliation (Chaldean Catholic Church, Assyrian Church of the East, Syriac Orthodox Church, Syriac Catholic Church, Assyrian Pentecostal Church, etc.) Assyrians Christians in Iraq and surrounding countries are one genetically homogeneous people and are of different origins than other groups in the country, with a distinct history of their own harking back to ancient Assyria and Mesopotamia.
Christians have inhabited modern-day Iraq for about 2,000 years, tracing their ancestry to ancient Mesopotamia and surrounding lands. The great patriarch Abraham came from Ur (modern-day Nasiriyah), while Isaac's wife Rebecca came from Assyria (in modern-day northwestern Iraq.) Additionally, Daniel lived in Iraq most of his life and the prophet Ezekiel was from southern Iraq and his shrine is located there. Shrines of the prophet Jonah and Saint George are also located there, and a number of other biblical prophets and saints are said to have been from there as well. Adam and Eve are also widely thought to have hailed from Iraq, as the biblical Garden of Eden is often believed to have been located in southern Iraq. Syriac Christianity was first established in Mesopotamia, and certain subsets of that tradition (namely the Church of the East and its successor churches) were established in northern and central-southern Iraq. This would become one of the most popular Christian churches in the Middle East and Fertile Crescent and would spread as far east as India and China.
