The Watergate scandals were a series of political scandals during the presidency of Richard Nixon that resulted in the indictment of several of Nixon's closest advisors, and ultimately his resignation on August 9, 1974 after his announcement in an address on August 8.

The scandals began with the arrest of five men for breaking and entering into the Democratic National Committee headquarters at the Watergate Office complex in Washington, D.C. on June 17, 1972. Investigations conducted by the Federal Bureau of Investigation (FBI), and later by the Senate Watergate Committee, House Judiciary Committee and the press revealed that this burglary was one of many illegal activities authorized and carried out by Nixon's staff and loyalists. They also revealed the immense scope of crimes and abuses, which included campaign fraud, political espionage and sabotage, illegal break-ins, improper tax audits, illegal wiretapping on a massive scale, and a secret slush fund laundered in Mexico to pay those who conducted these operations. This secret fund was also used as hush money to buy silence of the seven men who were indicted for the June 17 break-in.

Nixon and his staff conspired to cover up the break-in as early as six days after it occurred. After two years of mounting evidence against the President and his staff, which included former staff members testifying against them in a Senate investigation, it was revealed that Nixon had a tape recording system in his offices and that he had recorded many conversations. Recordings from these tapes revealed that he had obstructed justice and attempted to cover up the break-in. This recorded conversation later became known as the Smoking Gun. After a series of court battles, the United States Supreme Court unanimously ruled in United States v. Nixon that the President had to hand over the tapes; he ultimately complied.

With certainty of an impeachment in the House of Representatives and of a conviction in the Senate, Nixon resigned ten days later, becoming the only US President to have resigned from office. His successor, Gerald Ford, would issue a controversial pardon for any federal crimes Nixon may have committed while in office.
