In 1869 the HBC "sold" Rupert's Land (received compensation for surrendering its trading monopoly back to the British Crown) to the expanding Canada. A lack of attention to concerns of the existing Red River settlers, Métis, and aboriginal groups caused Métis leader Louis Riel to establish a local provisional government to negotiate the political treatment of the local population in the handover to Canada, resulting in the Red River Rebellion of 1869-70 and Canada agreeing to create the province of Manitoba – on land that had been part of the Selkirk Concession – in 1870.
The transfer of Rupert's Land from the HBC to Canada, coupled with the lack of attention towards the concerns of Red River settlers, Métis, and Indigenous groups, led to Louis Riel establishing a provisional government to negotiate their political treatment during the handover. This event resulted in the Red River Rebellion (1869-70) and the creation of Manitoba (on land previously part of the Selkirk Concession).
