Under Pan-Arabism or Arabian nationalism refers to a nationalist movement, the Arab culture nation, in the sense of a common language and culture, that is all Arabs from the Atlantic to the Persian Gulf, wants to unite in a common nation-state, rather than today's many Arab states.

The Arab national idea originated in the time of the Ottoman Empire. Islamic reformers under the Ottoman rule ( ie before the First World War) translated the French " patrie " with the term " Watan ". So the vision of the Islamic ummah ( Islamic community ) was shaken under the Ottoman Empire and replaced by the "nation".

Hailing from an orthodox Christian family Syrian Michel Aflaq, mastermind of Baathism as a pan-Arab ideas and policy direction and co-founder of the Baath Party then expands an important role. Gamal Abdel Nasser was after he took power in 1954 to a fervent advocate of Arab nationalism in the sense of Nasserism. To him also the Arab nationalist movement oriented. Nasser managed for a short time, to unite the states of Egypt and Syria to form the United Arab Republic. In response, the Iraqi King Faisal II and his Jordanian cousin Hussein I. founded the Arab Federation, which, however, was only six months in February 1958. Another representative of the pan-Arab idea was also Revolustionsführer Libya Muammar Gaddafi, who saw himself as Nasser's students and among others Arab Federation for the republics uttered, but also numerous other projects proposed agreement.

The pan-Arabism was an ideology that created an identity, namely the Arab- Islamic identity. This newly formed national identity conferred thinkers of pan-Arabism a meaning that is inseparable from Islam, which is confirmed by Aflaq.

After the 1967 Six Day War, Arab nationalism became more and more in a crisis and had to make it across long distances Islamic fundamentalism place. Arab nationalism evolved due to the increasing power of the Nasserist and later the Baathists to a instrument of oppression of the national minorities in the Arab countries.

The pan-Arabism sees the division of Arab unity as a result of colonization by different occupiers.
