 The Supreme Court case Malbury v. Madison was significant because it established the power of judicial review.

Explanation: Malbury v. Madison was a U.S Supreme Court case that was argued and decided in 1803. This was a landmark case because it established the principle of judicial review, which is based on a court's power to invalidate laws and acts for going against what has been established in the Constitution, that is to say for being unlawful. The decision of the Supreme Court in the Malbury v. Madison case was considering Section 13 of the Judiciary Act of  1789 unconstitutional.

the committees of correspondence were the american colonies’ means for maintaining communication lines in the years before the revolutionary war. in 1764, boston formed the earliest committee of correspondence to encourage opposition to britain’s stiffening of customs enforcement and prohibition of american paper money. the following year, new york formed a similar committee to keep the other colonies notified of its actions in resisting the stamp act. in 1773, the virginia house of burgesses proposed that each colonial legislature appoint a committee for intercolonial correspondence. the exchanges that followed built solidarity during the turbulent times and bring about the formation of the first continental congress in 1774.
