Maryland is a state located in the Mid-Atlantic region of the United States, bordering Virginia, West Virginia, and Washington, D.C. to its south and west; Pennsylvania to its north; and Delaware to its east. Maryland was the seventh state to ratify the United States Constitution, and has three occasionally used nicknames: the Old Line State, the Free State, and the Chesapeake Bay State. Maryland is also considered to be the birthplace of religious freedom in America, dating back to its earliest colonial days when it was made a refuge for persecuted Catholics from England by George Calvert the first Lord Baltimore, and the first English proprietor of the then-Maryland colonial grant. Maryland is one of the smallest states in terms of area, as well as one of the most densely populated states of the United States. Maryland has the highest median household income, making it the wealthiest state in the nation. The state’s largest city is Baltimore, and its capital is Annapolis. Although the state is officially claimed to be named after Queen Henrietta Maria, some Catholics believe Maryland was named after Mary, the mother of Jesus, by George Calvert, 1st Lord Baltimore prior to his death in 1632. The original intent may never be known. There is a St. Mary’s County in Maryland.
