Islamism is a range of religious and political ideological movements that believe that Islam should influence political systems. Its proponents believe Islam is innately political, and that Islam as a political system is superior to communism, liberal democracy, capitalism, and other alternatives in achieving a just, successful society. The advocates of Islamism, also known as "al-Islamiyyun", are usually affiliated with Islamic institutions or social mobilization movements, emphasizing the implementation of sharia, pan-Islamic political unity, and the creation of Islamic states.
In its original formulation, Islamism described an ideology seeking to revive Islam to its past assertiveness and glory, purifying it of foreign elements, reasserting its role into "social and political as well as personal life"; and in particular "reordering government and society in accordance with laws prescribed by Islam" (i.e. Sharia). According to at least one observer (author Robin Wright), Islamist movements have "arguably altered the Middle East more than any trend since the modern states gained independence", redefining "politics and even borders". Another sole author (Graham E. Fuller) has argued for a broader notion of Islamism as a form of identity politics, involving "support for [Muslim] identity, authenticity, broader regionalism, revivalism, [and] revitalization of the community."
