What is the line of jurisprudence that established the exclusionary rule as a necessary remedy for 4th amendment violations?

The Supreme Court changed the Fourth Amendment jurisprudence through its ruling in Weeks v. United States in 1914. This case involved a defendant's appeal who was convicted on evidence seized by a federal agent with no warrant or constitutional basis. The SC reversed the conviction, in effect leading to what is now known as the "exclusionary rule." In Mapp v. Ohio in 1961, the SC made this rule applicable to all of the states.
