Arab identity
In the modern era, defining who is an Arab is done on the grounds of one or more of the following three criteria:

Distribution of Arabic as sole official language (green) and one of several official or national languages (blue).Genealogical: someone who can trace his or her ancestry to the tribes of Arabia - the original inhabitants of the Arabian Peninsula - and the Syrian Desert. This definition was the definition used in medieval times, for example by Ibn Khaldun, but has decreased in importance as more people have come to identify as Arabs.
Linguistic: someone whose first language, and by extension cultural expression, is Arabic, including any of its varieties. This definition covers more than 300 million people. Certain groups that fulfill this criterion reject this definition on the basis of non-Arab ancestry, such an example may be seen in the way that Egyptians identify themselves.[17][18]
Political: in the modern nationalist era, any person who is a citizen of a country where Arabic is either the national language or one of the official languages, and/or a citizen of a country which may simply be a member of the Arab League (thereby having Arabic as an official government language, even if not used by the majority of the population). This definition would cover over 300 million people. It may be the most contested definition, as it is the most simplistic one. It would exclude the entire Arab diaspora outside of the Arab world, but include not only people with Arab ancestry (Gulf Arabs and others, such as Bedouins, where they may exist) or who identify themselves as Arabs, but would also include Arabized groups who do not identify themselves as Arabs (including many Lebanese and many Egyptians, both Christians and Muslims) and even non-Arabized ethnic minorities who have remained non-Arabic-speaking (such as the Berbers in Morocco, Kurds in Iraq, or the Somali majority of Arab League member Somalia).
