King was jailed several times. Federal Bureau of Investigation (FBI) director J. Edgar Hoover considered King a radical and made him an object of the FBI's COINTELPRO from 1963 forward. FBI agents investigated him for possible communist ties, spied on his personal life, and secretly recorded him. In 1964, the FBI mailed King a threatening anonymous letter, which he interpreted as an attempt to make him commit suicide. On October 14, 1964, King won the Nobel Peace Prize for combating racial inequality through nonviolent resistance. In his final years, he expanded his focus to include opposition towards poverty and the Vietnam War.
