1. In 1820, Maine became the 23rd state in the United States. This occurred on March 15, but it is notable because it was the result of the Missouri Compromise, which established a balance between free and slave states in the country.

2. On November 11, 1940, the State of Maine suffered one of the worst fires in its history. The town of Bar Harbor was completely destroyed, along with a large portion of Acadia National Park. The fire was started by sparks from a hunter's campfire, and it burned for three days, destroying 164 homes and leaving over 10,000 people homeless.

3. In 1984, Maine held its first gubernatorial election in which a woman, former Congresswoman Olympia Snowe, won a major party's nomination. Although she lost the general election to incumbent Joseph Brennan, Snowe went on to serve as a U.S. Senator from Maine for 18 years.

4. November 11 is also known as Veterans Day in the United States, a holiday honoring military veterans who have served in the U.S. Armed Forces. In Maine, many communities hold parades and ceremonies to honor veterans on this day.

5. On November 11, 1896, the first trolley line in Maine was opened in Portland. The line, which operated along Congress Street, was part of a larger network of trolleys that connected cities and towns throughout the state. The trolley system remained in operation until the 1930s, when it was replaced by buses and automobiles.
