November 9 is the International Day Against Fascism and Anti-Semitism [UNITED factsheet].
On November 9, 1924, American gay activist Henry Gerber and several associates formed the Society for Human Rights, the first gay rights organization in the United States.

The Society received a charter from the State of Illinois in December, but was disbanded in July 1925 after a police raid which led to Gerber's arrest and trial (albeit not conviction). Pay a virtual visit to Henry Gerber House, now a registered Chicago landmark.

On November 9, 1970, the Supreme Court voted 6-3 in Massachusetts v. Laird not to hear the case of the state's anti-draft law.

Massachusetts had passed a law, which allowed its citizens to decline to fight in any undeclared war, even if the person was drafted. The law was passed in opposition to the draft and the war in Vietnam. The 1st Circuit found the war constitutional and thus struck down the law.
