 Manitoba's official tartan was designed in 1962 by Hugh Kirkwood Rankine, and officially adopted by the province in "The Coat of Arms, Emblems and the Manitoba Tartan Act", which received Royal Assent on May 1 of that year.The red in the design originates from the Red River Colony, founded in 1812 by the Earl of Selkirk, Thomas Douglas, and crofters from the Scottish Highlands, and the blue was taken from the Clan Douglas tartan.In addition, the green lines represent the varying cultures and races that make up Manitoban society, and the gold represents Manitoba's agricultural history.
