Relating to or characteristic of federalism or federalists; supporting the principles of federal government organization.
From federalist plus the adjectival suffix -ic, meaning 'of or relating to,' creating an adjective form that describes things associated with federalism.
A federalistic system shows up all over the world—the U.S., Canada, Australia, Germany, India, Brazil—which proves that when you have really diverse populations spread over huge areas, dividing power between central and local governments works better than having everything controlled from one capital city.
