In March 1945, representatives from six Arab nations gathered in Cairo, Egypt, to adopt a charter that established the Arab League. This organization was created in response to the growing need for cooperation among Arab countries following the complexities arising from World War II and the shifting global landscape. The league's founding members were Egypt, Iraq, Transjordan (later Jordan), Lebanon, Saudi Arabia, and Syria. They convened with the goal of promoting political, economic, and cultural collaboration across the Arab world, ensuring that Arab nations could collectively address issues relevant to their interests and security.

The charter outlined various areas of cooperation, including defense, economic collaboration, and cultural exchange, emphasizing the importance of unity among Arab states. The establishment of the Arab League also coincided with the waning influence of European colonial powers in the region, further highlighting the importance of self-governance and solidarity among newly independent nations. Over subsequent years, the league expanded its membership, eventually encompassing 22 countries and providing a framework for collective action and dialogue on regional issues.

The adoption of the charter was a landmark moment for Arab nationalism, signaling a shift towards greater political organization among the Arab states. The league aimed to address common challenges including economic development, territorial disputes, and the quest for peace in the wake of colonialism and conflict. It became a platform for addressing critical issues like the Palestine question, further involving itself in regional conflicts and peace initiatives.
