Arab identityArab identity (الهوية العربية) is the objective or subjective state of perceiving oneself as an Arab and as relating to being Arab. Like other cultural identities, it relies on a common culture, a traditional lineage, the common land in history, shared experiences including underlying conflicts and confrontations. These commonalities are regional and in historical contexts, tribal. Arab identity is defined independently of religious identity, and pre-dates the spread of Islam and before spread of Judaism and Christianity, with historically attested Arab Muslim tribes and Arab Christian tribes and Arab Jewish tribes.
Arab nationalismArab nationalism (القومية العربية al-Qawmīya al-ʿArabīya) is a political ideology asserting that Arabs constitute a single nation. As a traditional nationalist ideology, it promotes Arab culture and civilization, celebrates Arab history, glorifies the Arabic language as well as Arabic literature, and calls for the rejuvenation of Arab society through total unification. It bases itself on the premise that the people of the Arab world — from the Atlantic Ocean to the Indian Ocean — constitute one nation bound together by a common identity: ethnicity, language, culture, history, geography, and politics.
Spread of IslamThe spread of Islam spans about 1,400 years. Muslim conquests following Muhammad's death led to the creation of the caliphates, occupying a vast geographical area; conversion to Islam was boosted by Arab Muslim forces conquering vast territories and building imperial structures over time. Most of the significant expansion occurred during the reign of the Rashidun from 632 to 661 CE, which was the reign of the first four successors of Muhammad.
