1. In 1781, the city of York became the capital of the newly independent Commonwealth of Pennsylvania. The government had previously been located in Philadelphia, but the British occupation of the city during the Revolutionary War made it necessary to move to a safer location.

2. On September 6, 1862, the Battle of Antietam began in Maryland. Although it was not fought on Pennsylvania soil, the bloodiest one-day battle in American history had significant repercussions for the state. President Lincoln used the Union victory to issue the Emancipation Proclamation, which declared that all slaves in Confederate-held territory would be free.
