What is separation of powers?
short paragraph

The separation of powers is a representation for the governance of a state. Under this model, a state's government is divided into branches, each with separate, independent powers and responsibilities so that powers of one branch are not in conflict with those of the other branches. The typical division is into three branches: a legislature, an executive, and a judiciary, which is the trias politica model. It can be contrasted with the fusion of powers in parliamentary and semi-presidential systems, where the executive and legislative branches overlap.
