What is gibbons vs Maryland?

Gibbons v. Maryland (1824) was a landmark Supreme Court case that clarified the scope of Congress's powers under the Commerce Clause of the Constitution. The case involved a dispute over steamboat operations on the Hudson River, where the state of New York granted a monopoly to one operator, which was challenged by Thomas Gibbons, who held a federal license. The Supreme Court ruled that the federal government had the authority to regulate interstate commerce, thereby invalidating state laws that interfered with this regulation. This decision reinforced the principle of federal supremacy over state laws in matters of interstate commerce.
