Suomalainen naisliitto (Hfrs), is a non-profit Finnish women's organization which was established in 1907.
Hagman as well as other leading members, such as Maikki Friberg and Tekla Hultin, were affiliated with the Young Finnish Party.
The Hfrs promoted women's emancipation by arranging courses and leactures.
Until the 1940s, it published its own magazine, the Naisten Ääni; Maikki Friberg was its editor in 1907–1927.
Nowadays Naisten Ääni https://www.naistenaani.fi/ is a data base collecting biographies of women.
