Facts About Maryland

Maryland’s Revolutionary War Legacy and Colonial Foundation

1. Maryland Earned Its “Old Line State” Nickname During Revolutionary War Heroics

Maryland’s most famous nickname, the “Old Line State,” comes from the heroic actions of 400 soldiers in the First Maryland Regiment during the Revolutionary War. These brave men fought against a British force of 10,000 troops, holding their line long enough for General George Washington’s army to escape. Washington himself praised the Maryland Line throughout the war, and their discipline and unwavering bravery in the face of overwhelming odds earned Maryland its enduring nickname that reflects the state’s commitment to American independence.

2. Queen Henrietta Maria of England Gave Maryland Its Royal Name

Maryland was named in honor of Queen Henrietta Maria, the wife of King Charles I of England, when the colony was founded in 1634. George Calvert, the first Lord Baltimore, originally received the charter for the colony, but he died before settlement could begin. His son, Cecil Calvert (2nd Baron Baltimore), inherited the proprietorship and named the colony after the queen as required by the royal charter, creating a lasting connection between Maryland and English royalty.

3. Maryland Was Founded as America’s First Religious Haven for Catholics

Cecil Calvert established Maryland specifically to provide a safe haven for England’s Roman Catholic minority, who faced persecution in their homeland. This made Maryland unique among the early American colonies, as it was intentionally designed to offer religious tolerance. Although Catholics remained a minority even in Maryland (less than 10% of the population), the colony’s founding principles of religious freedom would later influence the development of American religious liberty.

4. The First Maryland Settlers Arrived at St. Mary’s City in 1634

Lord Baltimore’s first colonists arrived in Maryland in March 1634 aboard the ships Ark and Dove, with Leonard Calvert (Cecil’s younger brother) serving as the first provincial Governor. They established their first permanent settlement at St. Mary’s City in what is now St. Mary’s County, purchasing the land from the local paramount chief who was eager to establish trade relationships. St. Mary’s City served as Maryland’s capital for 60 years until the seat of government moved to Annapolis in 1695.

5. Maryland Contributed Land for the Creation of Washington, D.C.

In 1790, Maryland, along with Virginia, donated land to the federal government for the creation of the nation’s capital. Maryland contributed approximately 70 square miles of territory from Montgomery and Prince George’s Counties, while Virginia provided about 30 square miles. This generous donation helped establish Washington, D.C., as the permanent seat of American government, with Maryland retaining its portion of the original diamond-shaped federal district when Virginia’s portion was returned in 1846.

Civil War Battles and Border State Complexities

6. The Battle of Antietam Was the Bloodiest Single Day in American History

On September 17, 1862, the Battle of Antietam near Sharpsburg, Maryland, became the deadliest single day in American military history. An estimated 23,000 soldiers were killed, wounded, or went missing during twelve hours of savage combat between Union and Confederate forces. This staggering casualty count exceeded the combined American losses from the Revolutionary War, War of 1812, and Mexican-American War, making Antietam a pivotal moment that demonstrated the true cost of the Civil War conflict.

7. Maryland Remained in the Union Despite Being a Slave State

Maryland faced a unique position during the Civil War as a slave state located south of the Mason-Dixon line that chose to remain loyal to the Union. This decision created major divisions within the state, with families often split between Union and Confederate sympathies. President Abraham Lincoln took extraordinary measures to keep Maryland in the Union, including suspending habeas corpus and arresting suspected Confederate sympathizers, because losing Maryland would have left Washington, D.C., surrounded by Confederate territory.

8. Fort McHenry Served as Both Inspiration and Civil War Prison

While Fort McHenry is famous as the birthplace of “The Star-Spangled Banner” during the War of 1812, it also served a crucial role during the Civil War as a military prison. The fort detained Confederate soldiers and suspected Southern sympathizers, including Baltimore Mayor George William Brown and even Francis Scott Key’s own grandson, journalist Frank Key Howard. This dual role demonstrates how Maryland’s strategic location made it central to multiple American conflicts.

9. Maryland’s State Song Once Called Lincoln a “Tyrant”

Maryland’s former official state song, “Maryland, My Maryland,” written by Confederate sympathizer James Ryder Randall, contained controversial lyrics referring to Abraham Lincoln as a “tyrant” and Union states as “northern scum.” The song remained Maryland’s official anthem for over 80 years until 2021, when Governor Larry Hogan signed legislation discontinuing its use. This change reflected Maryland’s evolution from its divided Civil War-era identity to its modern values of unity and inclusion.

10. The Mason-Dixon Line Defined Maryland’s Northern Border and America’s Division

The Mason-Dixon Line, surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon, established Maryland’s northern boundary with Pennsylvania and became the symbolic dividing line between free and slave states before the Civil War. This 244-mile boundary line resolved a century-long border dispute between Maryland, Pennsylvania, and Delaware, but it later gained national significance as the informal boundary between the North and South, making Maryland a true border state during the Civil War.

Maritime Heritage and Chesapeake Bay Wonders

11. The Chesapeake Bay Is America’s Largest Estuary

The Chesapeake Bay, which splits Maryland into two distinct halves, is the largest estuary in the United States, covering approximately 64,000 square miles and stretching 200 miles from north to south.

Captain John Smith was among the first Europeans to explore this natural wonder in 1608.

12. Maryland Leads the Nation in Blue Crab Production

Maryland is renowned for producing more blue crabs than any other state, with the Chesapeake Bay providing ideal habitat for these prized crustaceans.

The iconic preparation involves steaming crabs with Old Bay seasoning, a spice blend that has become synonymous with Maryland cuisine and culture.

13. Assateague Island Features Wild Ponies That Swim Between States

Assateague Island, shared between Maryland and Virginia, is famous for its population of wild ponies that have roamed the barrier island for centuries.

14. The Port of Baltimore Ranks Among America’s Busiest Maritime Hubs

Located just 14 miles from the Chesapeake Bay’s mouth, the port handles over 40 million tons of cargo annually, including automobiles, containers, and bulk commodities. The port’s strategic location and deep-water access have made it essential to Maryland’s economy and America’s international trade for over three centuries.

15. Maryland Has Over 2,000 Miles of Tidal Shoreline

Despite being one of the smaller states, Maryland boasts more than 2,000 miles of tidal shoreline thanks to the complex geography of the Chesapeake Bay and its numerous tributaries. This extensive coastline includes sandy beaches, rocky cliffs, marshlands, and protected coves that provide habitat for countless species and recreational opportunities for millions of visitors. The intricate shoreline contributes to Maryland’s nickname “America in Miniature” due to its diverse coastal environments.
