Post-Islamism is a neologism in political science, the definition and applicability of which has led to an intellectual debate. Asef Bayat and Olivier Roy are among the main architects of the idea.
The term was coined by Iranian political sociologist Asef Bayat, then associate professor of sociology at The American University in Cairo in a 1996 essay published in the journal Middle East Critique.
Bayat explained it as "a condition where, following a phase of experimentation, the appeal, energy, symbols and sources of legitimacy of Islamism get exhausted, even among its once-ardent supporters. As such, post-Islamism is not anti-Islamic, but rather reflects a tendency to resecularize religion." It originally pertained only to Iran, where "post-Islamism is expressed in the idea of fusion between Islam (as a personalized faith) and individual freedom and choice; and post-Islamism is associated with the values of democracy and aspects of modernity". In this context, the prefix post- does not have historic connotation, but refers to the critical departure from Islamist discourse. Bayat later pointed in 2007 that post-Islamism is both a "condition" and a "project".
"Postmodern Islamism" and "New Age Islamism" are other terms interchangeably used.
French politician Olivier Carré used the term in 1991 from a different perspective, to describe the period between the 10th and the 19th centuries, when both Shiite and Sunni Islam "separated the political-military from the religious realm, both theoretically and in practice".
