Canth, whose birth anniversary is celebrated as the day of social equality in Finland, was also among the first female journalists in the world. She initially used to edit and write for 'Keski-Suomi' and eventually started her own newspaper 'Wapaita Aatteita' with fellow journalist August Makela.
Through her literary works, Canth constantly pushed and campaigned for workers' rights and feminism. She also wrote a famous play 'Tyomiehen Vaimo', which was about an alcoholic man who wastes his wife's money and property. Despite being controversial, the play was effective as the Finnish government subsequently passed a new law about the separation of property.
It was due to Canth's activism and literary works that Finland became the first European nation to give its women the right to vote in 1906. A year later, it became the first country in the world to elect women to its parliament.
She is also the first woman to receive her own flag day in Finland.
