Which landmark case involved a dispute over a New York state steamboat monopoly?

Gibbons v. Ogden is a landmark case that addressed the issue of interstate commerce and the federal government's authority over it. The case arose from a conflict between two steamboat operators who were operating under state-granted monopolies. Specifically, one operator, Aaron Ogden, held a monopoly granted by the state of New York, which allowed him to operate steamboats in its waters. The other operator, Thomas Gibbons, had a federal license to operate in interstate waters.

The Supreme Court, led by Chief Justice John Marshall, ruled in favor of Gibbons, stating that the federal government had the sole authority to regulate interstate commerce, which included navigation. This decision established that states could not interfere with congressional control over interstate commerce, thus reinforcing the power of the federal government and setting a precedent for future cases related to economic regulation. The outcome of this case significantly impacted the development of commerce and trade across state lines, promoting a more unified national economy.
