What are some differences between Pan-Arabism and Islamic Nationalism?

Answer 1

The two are completely opposite ideologies.

Pan-Arabism: Supporters of Pan-Arabism believe that the Arab World should be one nation similar to the Umayyad Caliphate as it was in the year 750 C.E. (without Persia or Southern Spain). They believe that the Arab World has borders that were artificially drawn by Europeans, Turks, and greedy Arab rulers and that the natural condition of the Arab people is to be in one large nation (similar to the United States). While Pan-Arabists have often discussed using Islam as a general framework for the laws of this Pan-Arab State, most Pan-Arabists believed in a secular government and only used Islam as a cultural marker, not a religious one.

Islamic Nationalism: Islamic Nationalism is a form of Islamism. Islamism is a political ideology whose goal is to bring the religious tenets of Islam into the daily functioning of a government and its laws. Islamism is a modern movement whose roots began contemporaneously with the rise of Salafism in the late 1800s and early 1900s in Egypt. Islamic Nationalism is not by nature violent or expansive and several Islamic Nationalist movements have concrete goals such as the Islamists in power in Turkey. Islamic Nationalists do not believe in one unified state for all Muslims, but in making each individual state act in accordance with Islamic principles. Islamic Nationalism also does not have an ethnic component, so Islamic Nationalism can be exported outside of the Arab World. It has taken root in Iran and Turkey and has advocated movements in South Asia and Africa.
