The exclusionary rule developed from which Supreme Court decision?

The exclusionary rule, which bars using evidence obtained through illegal searches and seizures, was extended to apply to state courts by Mapp v. Ohio. In that decision, the Supreme Court held that the Fourth Amendment protections against unreasonable searches and seizures must be applied to the states through the Fourteenth Amendment’s Due Process Clause, so evidence gathered in violation of those rights cannot be used in state criminal trials. This effectively nationalized the exclusionary rule, moving it beyond federal prosecutions. The other cases address different issues: Gideon v. Wainwright guarantees the right to counsel; Katz v. United States concerns a reasonable expectation of privacy; Brown v. Board of Education deals with racial segregation and equal protection. Thus, Mapp v. Ohio is the decision that developed the exclusionary rule for state cases.
