The Danish Women's Society or DWS is Denmark's oldest women's rights organization. It was founded in 1871 by activist Matilde Bajer and her husband Fredrik Bajer; Fredrik was a Member of Parliament and the 1908 Nobel Peace Prize laureate. The association stands for an inclusive, intersectional and progressive liberal feminism, and advocates for the rights of all women and girls and LGBT rights. It publishes the world's oldest women's magazine, Kvinden & Samfundet, established in 1885. The Danish Women's Society is a member of the International Alliance of Women and is a sister association of the Norwegian Association for Women's Rights and the Icelandic Women's Rights Association.

Liberal feminism, also called mainstream feminism, is a main branch of feminism defined by its focus on achieving gender equality through political and legal reform within the framework of liberal democracy and informed by a human rights perspective. It is often considered culturally progressive and economically center-right to center-left. As the oldest of the "Big Three" schools of feminist thought, liberal feminism has its roots in 19th century first-wave feminism seeking recognition of women as equal citizens, focusing particularly on women's suffrage and access to education, the effort associated with 19th century liberalism and progressivism. Liberal feminism "works within the structure of mainstream society to integrate women into that structure." Liberal feminism places great emphasis on the public world, especially laws, political institutions, education and working life, and considers the denial of equal legal and political rights as the main obstacle to equality. As such liberal feminists have worked to bring women into the political mainstream. Liberal feminism is inclusive and socially progressive, while broadly supporting existing institutions of power in liberal democratic societies, and is associated with centrism and reformism. Liberal feminism tends to be adopted by white middle-class women who do not disagree with the current social structure; Zhang and Rios found that liberal feminism with its focus on equality is viewed as the dominant and "default" form of feminism. Liberal feminism actively supports men's involvement in feminism and both women and men have always been active participants in the movement; progressive men had an important role alongside women in the struggle for equal political rights since the movement was launched in the 19th century.
