Raden Adjeng Kartini is a Javanese noblewoman and is known as a pioneer in the area of women's rights for native Indonesians. For a young girl at that period of time (1879-1904) her thinking was quite progressive. She protested the gender inequality of Javanese traditions such as forced marriages at a young age, which denied women the freedom to pursue an education. In 1903 she opened the first Indonesian primary school for native girls that did not discriminate the students on the basis of their social status. To Kartini, the ideal education for a young woman should encourage empowerment and enlightenment. She died at a very young age. To honor her progressive idea, her birthday, April 21st, is celebrated through out Indonesia, by wearing traditional clothing such as kebaya.
