What political concept was introduced by North Africa's middle class?

The political concept introduced by North Africa's middle class that's often associated with the region is Arab nationalism. Arab nationalism is a political ideology that emerged in the 19th and 20th centuries and gained particular momentum after World War II, leading up to the independence of several North African countries from European colonial rule. The idea was to foster a sense of unity and solidarity among Arab peoples, transcending the existing state borders that were often arbitrarily set by colonial powers.

It is important to note, however, that unlike some Western societies where the middle class often leads political and social movements, in North Africa and much of the Arab world, the concept and constitution of the "middle class" can be quite different. Factors such as tribal affiliations, military structures, and religious leadership often play a more significant role in societal changes and political concepts than the economic middle class as understood in Western terms. Additionally, political Islam and other ideologies have also been significant in North Africa.
