St. Mary's County, located in the southernmost part of the state of Maryland, holds a significant place in American history as the site of Maryland's first permanent English settlement. The area was initially inhabited by the Yaocomico Native American tribe. In March 1634, a group of English colonists sailed up the Chesapeake Bay and established the settlement of St. Mary's City, named after the Virgin Mary.

St. Mary's City quickly grew into a bustling colonial capital and served as the seat of Maryland's government for over 60 years. It was a center for trade and commerce, with tobacco being the primary cash crop grown in the county. The colonists also established Maryland's first Catholic parish, St. Mary's Catholic Church, which still stands today as a historic landmark.

During the 17th century, St. Mary's County faced several challenges, including conflicts with Native American tribes and religious tensions between Catholics and Protestants. In 1695, the capital was moved to Annapolis, leading to a decline in St. Mary's City's importance. By the early 18th century, the county's economy shifted away from tobacco towards agriculture, lumber, and fishing.

In the 20th century, St. Mary's County experienced significant growth due to its proximity to Washington, D.C., and the establishment of naval and research institutions. During World War II, the Patuxent River Naval Air Station was established in St. Mary's County, which played a crucial role in the development and testing of naval aircraft. In recent decades, the county's economy has diversified with the growth of technology and defense industries, including the establishment of the St. Mary's County Technology and Industrial Park. Today, St. Mary's County is known for its rich historical heritage, beautiful waterfront scenery, and thriving aerospace and defense sectors.
