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 and our contribution to the evolution of our nation.
Together these “Mosaic Pieces” provide a distinctively unique picture of the energy, growth, accomplishments, setbacks and disputes in our border state.
Many of these firsts show the progress and achievement of America. Some show distinct regional differences and strong conflicts that have damaged our common life. But all are important building blocks for our state and country.
The Pieces create a whole Mosaic which is offered to the state and its citizens. The Mosaic provides an opportunity to reflect on the present and future in light of our past.
