Flag of the Arab Revolt in the context of "Pan-Arab"

Arab nationalism (Arabic: القومية العربية, romanized: 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, the Arabic language and Arabic literature. It often also calls for unification of Arab society. It bases itself on the premise that the people of the Arab world—from the Atlantic Ocean to the Arabian Sea—constitute one nation bound together by a common identity — ethnicity, language, culture, history, geography, and politics.

Rooted in the 19th-century Nahda under Ottoman rule, Arab nationalism emerged in the early 20th century as an opposition movement in the Arab provinces of the Ottoman Empire, later evolving into the overwhelmingly dominant ideological force in the Arab world. Initially focused on resisting Ottoman control, it later opposed Western imperialism after World War I due to the undesirable outcome of the Arab Revolt — in successfully achieving their primary goal of dissolving the Ottoman Empire, the Arab rebels simultaneously enabled the partitioning of their would-be unified Arab state by Britain and France. Anti-Western sentiment grew as Arab nationalists rallied around the Palestinian cause, viewing Zionism as a threat to the region's integrity and linking the Arab–Israeli conflict to Western imperialism due to the Balfour Declaration. Arab unity was considered a necessary instrument to "restoring this lost part" of the nation, which in turn meant eliminating the "relics" of foreign colonialism. Its influence steadily expanded over subsequent years. By the 1950s and 1960s, the charismatic Egyptian leader Gamal Abdel Nasser championed Arab nationalism following his seizure and nationalization of the Suez Canal and his "victory" over British–French–Israeli forces in the 1956 Suez Crisis, and political parties like the Ba'ath Party and the Arab Nationalist Movement demonstrated remarkable capabilities for mobilization, organization, and clandestine activities. This ideology seemed to be on the rise across the Arab states, with independent Arab governments such as Syria, Iraq, Algeria, and Egypt adopting Arab nationalism as official state policy.

Pan-Arabism (Arabic: الوحدة العربية, romanized: al-waḥda al-ʿarabiyyah, lit. 'Arab unity') is a pan-nationalist ideology that espouses the unification of all Arab people in a single nation-state, consisting of all Arab countries of West Asia and North Africa from the Atlantic Ocean to the Arabian Sea, which is referred to as the Arab world. It is closely connected to Arab nationalism, which asserts the view that the Arabs constitute a single nation. 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. Advocates of pan-Arabism have often espoused Arab socialist principles and strongly opposed the political involvement of the Western world in the Arab world. It also sought to empower Arab states against outside forces by forming alliances such as the Arab League.

The pan-Arab colors are black, white, green and red. Individually, each of the four pan-Arab colors were intended to represent a certain aspect of the Arab people and their history.

The Aqaba Flagpole in Aqaba, Jordan is a 130-metre (430 ft) tall flagpole. This height makes it the ninth tallest free–standing and tenth tallest flagpole in the world. It was the tallest free–standing flagpole in the world until being surpassed by the 133-metre (436 ft) tall Ashgabat Flagpole in 2008. It carries the flag of the Arab Revolt commemorating the Battle of Aqaba that took place in 1917. The flagpole can be seen from Israel, Egypt, and Saudi Arabia. The flagpole was built in 2004 and opened on 3 October 2004.
