September 13 in history:
New York City became the first official capital of the United States on September 13th, 1788. George Washington was sworn in as president there the following year. By 1790, the capital was moved to Philadelphia.
Margaret Chase Smith was a pioneer at the U.S. Capitol. Mrs. Smith had succeeded her late husband in the House, and on September 13th, 1948, she was elected to the U.S. Senate from Maine. That made her the first woman to be elected to both houses of Congress.
Maine was not a state yet during the War of 1812, so it was not represented on the “star-spangled banner” that flew over Ft. McHenry in Baltimore on this date in 1814. Francis Scott Key wrote his famous poem about the 15-star, 15-stripe flag that continued to fly over the fort after a British attack.
