Which U.S. state is nicknamed the "Old Line State"?

Thought it had to do with the Mason Dixon Line.

Maryland was also instrumental in beating the British in the War of 1812. Maryland militia defended the city of Baltimore at Fort McHenry and Francis Scott Key wrote the song that became the National Anthem.

I find it curious that there was no mention of the Mason-Dixon line.

Player #28745786, it was a battle during the Revolutionary War

Did not know this thank goodness for majority vote!

Player Meyer, No, he only wrote the lyrics - as a poem. The melody came from a popular drinking song. (Were inebriated singers the reason for the insane range of the melody?)

Interesting fact, Mason Dixon line separates Pennsylvania and Maryland with Maryland on south side, and Maryland was a slavery legal state before Civil War. But because Maryland stayed in the Union, it's easy to think it is on north side of line.

penawareof, I did too. I got it right though. Maryland just made sense...

I grew up on Long Island and never heard of the battle of long island

penawareof, me too.

Mason Dixon Line.

penawareof, Where is the Mason Dixon Line...... Has anybody ever seen it?
