This chapter explores how Raden Ajeng Kartini (1879?1904) incorporated the idea of cosmopolitanism into her writings. From her seclusion behind the walls of the Jepara Regency House in the Dutch East Indies, she reached the outside world through letters, which she wrote in Dutch. Kartini was known in Indonesia as a pioneer in education and women’s emancipation despite eventually being pressured to enter a polygamous marriage. This chapter discusses how she explored the concepts of the ‘centre’ and ‘periphery’, as well as ‘space’ and ‘place’, when colonialism was at its height. Kartini’s image, however, kept changing in Indonesia with each turn in the country’s socio-political situation, so that her ideas continued to be interpreted differently.
