Alberta is one of the thirteen provinces and territories of Canada.
Before becoming part of Canada, Alberta was home to several First Nations like Plains Indians and Woodland Cree. It was also a territory used by fur traders of the rival companies Hudson’s Bay Company and North West Company. The Dominion of Canada bought the lands that would become Alberta as part of the NWT in 1870. From the late 1800s to early 1900s, many immigrants arrived to prevent the prairies from being annexed by the US. Growing wheat and cattle ranching also became very profitable. In 1905, the Alberta Act was passed, creating the province of Alberta. Massive oil reserves were discovered in 1947. The exploitation of oil sands began in 1967.
