Martin was one of the founders of the Scandinavian Voting Association.[4] From 1907 to 1914, Martin took an active part in the campaign for American women's suffrage. When the Scandinavian Woman Suffrage Association was founded in 1907 by Ethel Edgerton Hurd, Martin became its first president, a role she held from 1907 to 1913.[5] After her retirement, she was succeeded by suffragette Nanna Mattson Jaeger.[2][6]
While she was president of the SWSA, Martin placed a large focus on the association's ethnicity. By looking at all the Scandinavian immigrant group (Norwegian, Swedish and Danish) as a whole, the membership would surpass all Scandinavian individual groups. As a Norwegian, Martin recruited many other Norwegians through various Norwegian cultural events, such as plays, speeches and lobbying campaigns. She was concerned with preserving the Scandinavian cultural heritage, in contrast with her successor Jaeger who championed the assimilation into American populace.[7] In 1913, Martin told the Minneapolis Tribune that Scandinavian women in Minneapolis "had no interest in woman suffrage" as Scandinavians in this country have been so busy making money that they are 50 years behind the times", a statement she retracted two days later with an explanation.[2]
Martin gave speeches in both Norwegian and English while garnering support for women's rights. When Minnesota's neighbouring state of North Dakota prepared to vote on a women's suffrage amendment to the state constitution, Martin travelled there to give speeches in both languages and to advise local suffragettes.[2][4] Her most famous speech was The Great Awakening, which she delivered at the annual meeting of the Minnesota Woman Suffrage Association in 1908.[2]
Between 1909 and 1922, Martin often contributed editorials to newspapers such as the Star Tribune and Minneapolis Star, expressing her progressive ideas. Martin also was a part of several clubs such as the Progressive Literary Club.[4]
