If you are asking for things that are associated with dates, you are probably asking for events, not facts. For example, if I said that politics in the 1960s became more contentious, that would be a fact, but it would have no date to associate with it. Therefore, I will give you 10 events that can be assigned dates.
- September 26, 1960. For the first time, there is a debate on national TV between the two men who are running for president. People who listen on the radio think Nixon won, people who saw it on TV think Kennedy won. This will represent a major change in the way presidential elections are run.
- November 8, 1960. John F. Kennedy is elected president in a very close election.
- June 29, 1964. The Civil Rights Act of 1964 is passed. This is the most important piece of Civil Rights legislation ever. Politically, it will help to move whites, particularly in the South, away from the Democratic Party.
- August 7, 1964. The Gulf of Tonkin Resolution is passed. This gives the president more power to get the US more involved in the Vietnam War.
- November 22, 1964. Kennedy is assassinated.
- November 3, 1964. Lyndon B. Johnson, who became president when Kennedy was assassinated, defeats Barry Goldwater in a landslide.
- August 6, 1965. The Voting Rights Act of 1965 is signed into law. This helps to ensure that state and local governments, particularly in the South, will no longer be able to prevent African Americans from voting.
- October 2, 1967. Thurgood Marshall becomes the first African American justice of the Supreme Court.
- April 4, 1968. Martin Luther King, Jr. is assassinated. This leads to rioting in inner cities around the country (there had been riots in inner cities in 1965 and 1967 as well).
- November 5, 1968. Richard Nixon is elected president. He is elected by consciously appealing to white conservative voters unhappy with civil rights and the lawlessness associated with the Counterculture and the inner city riots.
