Secular government separates political authority from religious authority, allowing law and state institutions to function without formal dependence on a specific faith. That separation does not erase religion from public life, but it changes the structure of power.

In plural societies, secular government often becomes a practical framework for coexistence. It is one of the ideas that made modern diversity more governable.
