The primary reason for Manitoba's entry into the Canadian confederation was the Red River Rebellion, which took place in 1869-1870. The rebellion was led by Louis Riel, a Métis leader who resisted the transfer of Rupert's Land, which included the Red River Colony, from the Hudson's Bay Company to Canada.
Riel and his followers seized control of Fort Garry, the main settlement in the Red River Colony, and established a provisional government. They issued a "Declaration of the People of Rupert's Land" setting out their demands, which included recognition of Métis land rights, the establishment of a provincial legislature, and the protection of French and Catholic rights.
The Canadian government responded to the rebellion by sending a military expedition under Colonel Garnet Wolseley to the Red River Colony. Wolseley arrived in Fort Garry in August 1870 and negotiated a peaceful surrender with Riel and his followers.
The Manitoba Act
As a result of the Red River Rebellion, the Canadian government passed the Manitoba Act in 1870, which created the province of Manitoba and admitted it into the Canadian confederation. The act also set out the terms of Manitoba's entry, including the recognition of Métis land rights, the establishment of a provincial legislature, and the protection of French and Catholic rights.
Economic Factors
In addition to the political factors that led to Manitoba's entry into the confederation, there were also economic factors that played a role. The Canadian government was eager to expand its territory and resources, and Manitoba offered both. The province had fertile land suitable for agriculture, as well as rich natural resources such as timber and minerals.
Social and Cultural Factors
Finally, there were also social and cultural factors that contributed to Manitoba's entry into the confederation. Many of the people living in the Red River Colony were of Scottish and English descent and had close ties to Canada. They saw joining the confederation as a way to maintain their cultural and economic connections with the rest of the country.
