Where 1963 fits
Why 1963 is special
1963 concentrated a great deal of American history into a few months. King delivered 'I Have a Dream' in August to a crowd of around 250,000; Kennedy was assassinated in Dallas in November. The Civil Rights Act that followed in 1964 is usually read as a consequence of both.
