This weekend will see if the film, The Revenant, will collect a plethora of film awards, including Leonardo DiCaprio’s coveted Oscars. But before we go into the game of will he or will he not—win the best actor award, that is—let’s take a look into how the Native Americans invested in areas, particularly gaming, in the nineteenth century.

The movie, directed by Alejandro Gonzalez Inarritu, is a classic survival tale that follows fur trapper Hugo Glass as he traverses the wilderness of North America. At the same time, the film also offers a glimpse at the tribes who called these territories home.

But what has become of these tribes today? There are currently 326 Indian reservations with 566 federally recognized tribes. One of these groups was the Arikara—the tribe that Glass came into contact with several times—now live in the Fort Berthold Reserve and form one of the federally recognized “Three Affiliated Tribes” in North Dakota. And like many other tribes, the Arikara have gone into the gaming industry and founded the 4 Bears Casino in New Town.

Casinos have played an important part in enabling tribes to get an income. According to a Unibet study, the success of Indian casinos began in 1970 when the Supreme Court declared that “not only do states not have authority to tax Indians on Indian reservations, but they also lack the authority to regulate Indian activities by Indians on Indian reservations.”
