Originally the Kentucky rifle was developed in Pennsylvania in the early 1700s and was widely used during the War of Independence (1775-1783), as settlers were familiar with them when used for hunting. These rifles accompanied the first American explorers in the western conquest and are often associated with Daniel Boone and Davy Crockett. When the American Civil War broke out (1861-1865), the Confederates used these rifles, due to the shortage of weapons.

The War of Independence of the United States was a long conflict, which faced the original Thirteen British Colonies in North America against the Kingdom of Great Britain for eight and a half years, ending with the British defeat at the Battle of Yorktown and the signature Of the Treaty of Paris.

The American Civil War was a very significant event in the history of the United States of America, which took place between 1861 and 1865. The two sides faced were the forces of the Northern states (La Union) against the newly Formed Confederate States of America, integrated by eleven states of the South, that proclaimed its independence.
