The events happened on 11th July are :
1804 : Aaron Burr and Alexander Hamilton duel : Outraged over disparaging remarks that Alexander Hamilton had allegedly made at a dinner party, Aaron Burr challenged his longtime rival to a duel, and on this day he fatally shot Hamilton on the heights of Weehawken, New Jersey. In 1800, Burr, the Republican candidate for vice president, had compelled Hamilton to acknowledge his authorship of The Public Conduct and Character of John Adams, Esq., President of the United States, a personal attack Hamilton had circulated privately, thereby bringing his quarrel with Adams into the open. When Thomas Jefferson and Burr received the same number of electoral votes (through an anomaly that would result in adoption of the 12th Amendment of the U.S. Constitution), the choice between them for president was cast into the House of Representatives, and Hamilton persuaded his Federalist colleagues to support their old Republican enemy Jefferson (who then won the presidency) rather than Burr.
1955 : The U.S. Air Force Academy officially opened at temporary quarters at Lowry Air Force Base in Denver, Colorado.

1863 : Angered by unfair practices in Civil War conscription, New York City workers rioted and attacked draft headquarters.
