How does Separation of powers protects against tyranny because?

Separation of powers protects against tyranny by dividing government responsibilities among distinct branches—typically, the executive, legislative, and judicial. This system ensures that no single branch can accumulate excessive power, as each branch has its own functions and can check the others through mechanisms like vetoes, judicial review, and legislative approval. By creating a balance of power, it prevents any one entity from dominating the government or infringing on individual rights, thereby safeguarding democracy and promoting accountability.
