The suffrage movement began in the late 19th century as women's organizations advocated for women's right to vote. By 1901, most western countries had granted universal male suffrage. In Canada, various groups campaigned for women's rights prior to 1900. During World War I, some women gained voting rights as wives and relatives of soldiers. Manitoba, Saskatchewan, and Alberta granted full women's suffrage in 1916-1917, followed by other provinces through 1918 and 1940. A famous court case in the 1920s determined women were not legally "persons", but this was later overturned on appeal. The Persons Case and advocacy of groups like the Famous Five were milestones for women's rights in Canada.
