The Fourth Amendment (Amendment IV) to the United States Constitution prohibits unreasonable searches and seizures and requires any search warrant to be judicially sanctioned and supported by probable cause. It is part of the Bill of Rights. The Fourth amendment was adopted in response to the abuse of the writ of assistance, a type of general search warrant issued by the British government. It was a major source of tension in pre-Revolutionary America. The Fourth Amendment was introduced in Congress in 1789 by James Madison, along with the other amendments in the Bill of Rights. They were proposed in response to Anti-Federalist objections to the new Constitution.
