In ancient philosophy in Asia, women made many vital contributions. In the oldest text of the "Upanishads", c. 700 BCE, the female philosophers Gargi and Maitreyi are part of the philosophical dialogues with the sage Yajnavalkya. Ubhaya Bharati (c. 800 AD) and Akka Mahadevi (1130–1160) are other known female thinkers in the Indian philosophical tradition. In China, Confucius hailed the female Jing Jiang of Lu (5th c. BCE) as being wise and an example for his students, while Ban Zhao (45–116) wrote several vital historical and philosophical texts. In Korea, Im Yunjidang (1721–93) were among the most notable women philosophers during the enlightened mid-Chosŏn era. Among notable female Muslim philosophers are Rabia of Basra (714–801), A’ishah al-Ba’uniyyah of Damascus (died 1517), and Nana Asma'u (1793–1864) from the Sokoto Caliphate of today's Nigeria. In early colonial Latin-America, the philosopher Sor Juana Inés de la Cruz (1651–95) was known as "The Phoenix of America".
