noun rev·e·nant \ˈre-və-ˌnän, -nənt\

The Revenant, staring Leo DiCaprio and directed by Alejandro G. Iñárritu, tells the story of a frontiersman on a fur trading expedition in the 1820s who must fight for survival after being mauled by a bear and left for dead by members of his own hunting team. It is based on the book The Revenant by Michael Punke, which itself is based on the story of an actual man named Hugh Glass.
There is very little about Hugh Glass that actually known outside of the fact that he was one of the “mountain men” who, during the turn of the 19th century were drawn out west in pursuit of the lucrative business of fur-trapping. Now, when Europeans came over from the new world, they found themselves awash in animals which they could use for fur trade (mainly beavers). From the boom in resources was developed a new trade of people named “mountain men”. The mountain man was a rare bred (there was usually only about 200-300 total) of person who braved the wild, hostile Native Americans, and the elements for months at a time before they returned to civilization. They even had their own system of medicine, called “frontier medicine, to deal with any injuries that may occur. Sure enough, though, by the 1800s they had hunted the beaver population in the Eastern portion of the country to near extinction. But luckily the United States had just invested in the Louisiana Purchase, which opened up St. Louis to the Rocky Mountains to these trappers. Hugh Glass was one of the men who ventured west to seek his fortune.
