Separation of Powers
Definition
The division of government into distinct branches, each with its own powers and responsibilities, to prevent any one branch from becoming too powerful.
Explanation
Most democratic governments divide power among three branches: the legislative (makes laws), the executive (enforces laws), and the judiciary (interprets laws). This system creates checks and balances where each branch can limit the power of the others. In the US, Congress is the legislature, the President leads the executive, and the Supreme Court heads the judiciary. In parliamentary systems like the UK, Canada, and Australia, the executive is drawn from the legislature, but the judiciary remains independent. The separation of powers is designed to prevent tyranny and protect individual rights.
Why this matters for your test
Understanding the three branches of government and how they check each other's power is essential for all citizenship tests.
