Alexandra Kollontai (1872–1952) was a distinguished Russian revolutionary, diplomat, and Marxist theorist. Born on March 31, 1872, in Saint Petersburg, Russia, she was a prominent advocate for women's rights and social justice. Kollontai played a significant role in the development of Soviet social policy and was the first woman to serve as a cabinet minister in an authoritarian government. Her work and ideas continue to influence discussions on gender equality and social reforms.
