Answer:
Federalism and Separation of Powers policies seek for decentralised the power and avoid tyranny.
Step-by-step explanation:
Separation of Powers, according to Montesquieu, is a policy that allow the country to have democracy, because this separation is constituted by three main autonomous powers: judicial, executive and legislative. Each institution can judge others, so this way whole nation power is not concentrated in one point.
In this way, Federalism is alike, because this policy is about having a central government (Federal), and regional governments (States) in a whole political system. So, each regional government has their own rules and freedom to their jurisdiction.
