Maine was the 23rd state in the USA; it became a state on March 15, 1820. - State Capital is Augusta. - Nickname is Pine Tree State. - Maine's official flag was adopted in 1909. The flag has a deep blue field with the state coat of arms in the center. The coat of arms pictures a farmer and a seaman (representing agricultural and maritime industries). A shield is between them, upon which is a pine tree, a moose (the state animal of Maine), green grass, a blue sky, and deep blue water. Above this is a yellow star (representing the North Star - Maine was the northernmost state when it entered the Union) and a red ribbon that reads, "DIRIGO," which means "I direct" in Latin.
