Maryland is a small state with a big history

Explore the maryland mosaic, a collection of historic firsts

The Maryland Mosaic is a collection of firsts in Maryland and in our nation, demonstrating the state’s leadership of and contribution to the evolution of our nation.

 

Many of these firsts, or Mosaic Pieces, show the progress and achievement of America. Some have created conflict and damaged our citizens. But all are important building blocks for our state and country.

America turns 250 on July 4, 2026

MAryland has contributed over 142 “National firsts” to our nation

The Maryland Mosaic was created in celebration of the 250th anniversary of the United States. The Mosaic is a collection of people, places, events, buildings, documents, and objects. The collection provides a unique picture of this small border state through the lens of its geography, political influence, participation in military conflict, and long history of collaboration between Black and White citizens. It has a statewide reach as at least one Mosaic Piece represents every county and Baltimore City.

More anniversaries to come

In 2029 Baltimore City will be 300 years old. In March of 2034, Maryland will commemorate 400 years as a colony and a state.


Maryland’s Four Centuries Project, a 501C3 non-profit grassroots organization, has taken the lead in presenting commemorative programming for these key anniversaries. Our 250th anniversary commemoration—the Maryland Mosaic—is unique in its focus on Maryland’s national firsts.
