In Arab political culture, the Naksa of 1967 had a number of watershed effects. Scholars have paid a lot of attention to the decline of secular Arab nationalism and the concurrent rise of Islamism. Much less research has been done on the way 1967 spurred radical left organizations, also known as ‘the new Arab left’, to organize resistance against Israel as well as gain a foothold in national politics. This article analyzes what 1967 meant for groups such as P.F.L.P., D.F.L.P., O.C.A.L. and the Syrian Communist Party - Political Bureau, and the wider political culture associated with the new left: its media, journals and art. Based on readings of this cultural production and new research on the tri-continental movement, revolutionary socialism and Third-Worldism in the late 1960s and early 1970s, the article argues that the defeat of 1967 helped to determine the shape the revolutionary moment that followed. This moment has had a lasting impact on Arab political culture and is being re-interpreted in interesting ways today by Arab revolutionaries post-2011.
