Arabs (Arabic: عرب, ʿarab) are a major panethnic group whose native language is Arabic, comprising the majority of the Arab world. They primarily inhabit Western Asia, North Africa, and parts of the Horn of Africa. Before the spread of Islam, Arab referred to any of the largely nomadic Semitic tribes inhabiting the Arabian Peninsula. In modern usage Arabic-speaking populations are a highly heterogeneous collection of peoples, with diverse ancestral origins and identities. The ties that bind the Arab people are common linguistic, cultural, and political traditions. As such, Arab identity is based on one or more of genealogical, linguistic or cultural grounds, although with competing identities often taking a more prominent role, based on considerations including regional, national, clan, kin, sect, and tribe affiliations and relationships. If the Arab panethnicity is regarded as a single population, then it constitutes the world’s largest group of people after the Han Chinese.
