It originated in the late 19th century among the Arab regions of the Ottoman Empire, and its popularity reached its height during the peak of Nasserism and Ba'athism in the 1950s and 1960s.
[4] A prominent figure was Jurji Zaydan (1861–1914), who played a key role in laying the intellectual foundation for Pan-Arabism.
Zaydan wrote several articles during the early 20th century which emphasized that Arabic-speaking regions stretching from the Maghreb to the Persian Gulf constitute one people with a shared national consciousness and that this linguistic bond trumped religious, racial and specific territorial bonds, inspired in part by his status as a Levantine Christian émigré in 19th century Egypt.

The belief held by critics emphasized that pan-Arabism separated itself from the Ummah in that it only promoted Arab unity and ideals, not Islamic ones.
The United Arab Republic, consisting of Egypt and Syria, received ideological burden due to the unfavorable outcome, thus putting pan-Arabism in question.
