Peale was the foremost portrait painter of the American colonies and early republic, responsible for painting the portraits of many our country's Founding Fathers. George Washington sat for no fewer than 14 Peale portraits, and was perhaps his most famous subject.
According to David C. Ward, author of the book, Charles Willson Peale: Art and Selfhood in the Early Republic, Peale created a visual record of early American nationalism through his portraits of the Founding Fathers of our country:
“Charles Willson Peale gave a face to America from 1765 to 1824… Peale built his reputation as the illustrator of the young Republic by producing hundreds of portraits of both political leaders and ‘middling people.’ These portraits tracked the growth of Americans’ material and intellectual self-confidence, celebrated the leaders and the participants in the cause of independence, and, as a collective biography of young America, contributed to a democratic ideology reconciling individualism and the nation-state.” [xviii, xx]
“Instead of history paintings, Peale painted portrait biographies of the revolutionary generation, creating a pantheon that would perpetuate American republicanism… Peale’s gallery offered a visual civics lesson on the founding of the Republic… Peale’s portraits democratized heroism, creating an identity between hero and the audience.” 
When John Sevier was a congressman in Philadelphia from 1789 to 1791, he sat for Peale for this portrait as part of an effort to document the heroes of the American Revolutionary War. As a lieutenant colonel, John Sevier played a key role in the pivotal Battle of King's Mountain, where the British and their leader, Major Patrick Ferguson, were soundly defeated by a rough band of frontiersmen from west of the Appalachian mountains.
These "Overmountain Men" of the upper Tennessee settlements were highly revered, and John Sevier was among the most celebrated of those heroes. Sevier's exploits in Tennessee's wilderness were legendary. He was well-known as an Indian fighter and land speculator before becoming the first Governor of Tennessee. Most first generation frontiersmen had little time to sit for portrait artists, but by the time John Sevier sat for Peale's portrait he had long since left the frontier way of life. He was a military war hero and a statesman, an image well-suited for Peale's documentary of the new republic, and an image that endured throughout John Sevier's political career.
Of course there were no cameras in John Sevier's time to capture images of his exploits, so Charles Willson Peale's stately military portrait of John Sevier ultimately became the visual memory of his accomplishments as a Revolutionary War veteran. Today, John Sevier is remembered as "Pioneer, Soldier, Statesman" due in no small measure to the brushstrokes of America's most famous artistic biographer, Charles Willson Peale.
