Which principle ensures that government power is not concentrated in one branch?

The principle of separation of powers is fundamental in preventing the concentration of government power within a single branch. This concept divides government responsibilities among different branches—typically the legislative, executive, and judicial branches—each with its own distinct functions and powers. By doing so, it creates a framework where no single branch can exercise unchecked power over the others, promoting a system of governance that encourages accountability and reduces the risk of tyranny.

In this system, the legislative branch creates laws, the executive branch enforces laws, and the judicial branch interprets laws. This structure inherently requires collaboration and oversight among the branches, further ensuring that one does not dominate the others. It is this clear delineation and balance of functions that secures a more stable government, where authority is dispersed and not concentrated in any one area. Understanding this principle is essential as it forms the backbone of modern democratic governance, ensuring liberty and justice within a society.
