Greek women writers have a long history dating back to antiquity with Sappho being considered the world's first female poet. However, from Sappho's time until later years, women's literary production faced great obstacles from men who held the view that writing was a male privilege. Some notable early women writers included Cassiani and Anna Komneni in the 12th century. In modern Greece, women began appearing in literature more in the late 18th and 19th centuries as enlightenment spread. However, critics still considered women's literature inferior to men's well into the early 20th century. Now in the 21st century, women's literary production in Greece is constantly increasing.
