The history of the Arabs is recorded to have begun in the mid-9th century BCE, corresponding with the earliest known attestation of Old Arabic. Tradition in the Abrahamic religions holds that Arabs are the descendants of Ishmael, who was the son of the Hebrew patriarch Abraham and his Egyptian concubine Hagar. The Syrian Desert, which includes an extension of the Arabian Peninsula, is the home of the first attested "Arab" groups, as well as other defined Arab groups that spread in the land and existed for millennia.
Before the expansion of the Rashidun Caliphate (632–661) during the early Muslim conquests, the word "Arab" referred to any of the largely nomadic or settled Arab tribes in the Arabian Peninsula, the Levant, and Upper and Lower Mesopotamia. Today, "Arab" refers to a variety of large numbers of people whose native regions form the Arab world due to Arab migrations and the concurrent spread of the Arabic language throughout the region, namely the Levant and the Maghreb, following the rise of Islam in the 7th century. During this period, they forged the Rashidun Caliphate (632–661), the Umayyad Caliphate (661–750), and the Abbasid Caliphate (750–1258). These Arab dynasties ruled some of the largest land empires in history, reaching southern France in the west, China in the east, Anatolia in the north, and Sudan in the south. In 1517, the Mamluk Sultanate of Cairo was conquered by the Ottoman Empire, which went on to rule much of the Arab world until World War I, after which it was defeated and dissolved and its territories partitioned, 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 while respecting the individual sovereignty of its member states.
