Sectarianism is a debated concept. Some scholars and journalists define it as pre-existing fixed communal categories in society, and use it to explain political, cultural, or religious conflicts between groups. Others conceive of sectarianism as a set of social practices where daily life is organized on the basis of communal norms and rules that individuals strategically use and transcend. This definition highlights the co-constitutive aspect of sectarianism and people's agency, as opposed to understanding sectarianism as being fixed and incompatible communal boundaries.
