Liberal 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 is also called "mainstream feminism", "reformist feminism", "egalitarian feminism", or historically "bourgeois feminism", among other names.
