Answer:
Three lasting influences that Britain had on the United States:
- language: the most obvious lasting influence. The United States is the largest english-speaking country in the world. This is a remarkable fact because a large part of the population of the United States descends from non-english speaking countries like Germany, Italy, Poland or Mexico.
- Common law: the legal system of the United States is based on British common law, where laws are less specific, and judges hold a great degree of power. This in contrast to the legal system of continental Europe: civil law, based on the Napoleonic code.
- Political culture: many political institutions of the United States draw inspiration form British political institutions, from liberalism to the Magna Carta.
