Can someone give me an example of how federalism is used today? ASAP, please !!

Federalism is a compromise meant to eliminate the disadvantages of both systems. In a federal system, power is shared by the national and state governments. so information is shared throughout the gov.

Examples of the federation or federal state include the United States, India, Brazil, Mexico, Russia, Germany, Canada, Switzerland, Argentina, Nigeria, and Australia. Some characterize the European Union as the pioneering example of federalism in a multi-state setting, in a concept termed the federal union of states.
