Centralized federalism revolves around the idea that the federal government should be the one setting national policy, and the state and local governments must be the ones to carry out these policies. Great Britain and France are examples of a centralized federalism.
In the United States, government responsibilities are divided between the federal and state governments. The federal government has the power to pass blanket laws or policies that affect each state, but the states also have the power to govern anyone within their borders. States within the UK, for example, do not have the same power. In that country, everything is controlled by the federal government.
