Arabs (Arabic: عَرَب) are an ethnic group mainly inhabiting the Arab world in West Asia and North Africa. A significant Arab diaspora is present in various parts of the world. Before the spread of Arabic language in the wake of the Arab conquests, "Arab" largely referred to the Semitic inhabitants—both settled and nomadic—of the Arabian Peninsula and the Syrian Desert. In modern usage, it includes people from across the Greater Middle East that share Arabic as a native language.
Arabs have been in the Fertile Crescent for thousands of years. In the 9th century BCE, the Assyrians made written references to Arabs as inhabitants of the Levant, Mesopotamia, and Arabia. Throughout the Ancient Near East, Arabs established influential civilizations starting from 3000 BCE onwards, such as Dilmun, Gerrha, and Magan, playing a vital role in trade between Mesopotamia, and the Mediterranean. Other prominent tribes include Midian, ʿĀd, and Thamud mentioned in the Bible and Quran. Later, in 900 BCE, the Qedarites enjoyed close relations with the nearby Canaanite and Aramaean states, and their territory extended from Lower Egypt to the Southern Levant. From 1200 BCE to 110 BCE, powerful kingdoms emerged such as Saba, Lihyan, Minaean, Qataban, Hadhramaut, Awsan, and Homerite emerged in Arabia. According to the Abrahamic tradition, Arabs are descendants of Abraham through his son Ishmael.
