Celebrate 250 years of history with OIRM! Join us April 17 for the opening of "Echoes of Time," our newest exhibit honoring the United States' 250th anniversary.

On April 17, 1783, Arkansas Post was attacked by British irregulars and Chickasaw led by Captain James Colbert. The Colbert Raid was the only battle fought in present-day Arkansas during the American Revolution and was the last land-based engagement of the conflict.

Travel back in time to Batesville’s celebration of the American Bicentennial in 1976. Learn about Jim Bechdoldt’s journey along the Bicentennial Wagon Train, which traveled from the West Coast to Valley Forge, Pennsylvania. Discover the symbols that represent our nation, from Lady Liberty to Uncle Sam. Visitors are also invited to reflect on what it means to be an American and what our role is in the nation’s ongoing democratic experiment.

Independence County, founded in 1820 and named in honor of the Declaration of Independence, offers visitors a chance to reflect on our region’s place in the history of the United States. Explore the communities and landmarks across our twelve-county region that are named after veterans of conflicts ranging from the Revolutionary War to World War II. The exhibit also provides an opportunity to remember the service and sacrifice of veterans past and present.

On July 4, 2026, the United States of America will celebrate the 250th anniversary of the signing of the Declaration of Independence.
