Maryland earned its nickname in one of the most important moments of history in the United States. During the Revolutionary War, George Washington made reference to the state as the Old Line State due the historic significance of the military’s forces known as the Maryland Line.

According to records, stories, and legends, the nickname of the Old Line State birthed due to the American Revolution. General George Washington is believed to have given the name this state because of its regular troop lines, known as the Maryland Line, the state made significant efforts towards freedom for the country during the war. In other words, Maryland is known as the Old Line State because of its immense contributions to the Revolutionary War via the Maryland Line (military troops).

There’s no desert here, but there are mountains, ocean coastal, rivers, streams, forests, farmland, and just about everything else you could see elsewhere in the country.

The beautiful Baltimore Oriole is perhaps the most recognizable symbol of the state apart from the flag. Females of the species have brown-olive to dull orange feathers. Males, on the other hand, have deep black and golden orange coloring. The coloring of the males is somewhat similar to that in the Calvert shield, which led to the association of the bird to the state.
