Mard, Mardangi and Mardvad (Hindi)
For billions of years there have been two opposite sexes. Male and female, these recently developed into two different factions. On the female side they developed feminism. On the male side they developed masculinity. For many years women lived in a male-centric society. In 1920's women got a lot if not most of the rights men have. The feminist movement started to rapidly rise in waves since about the 19th century.
