Kashet

Kashet was the second planet of the Isis Kash system and the homeworld of the Kasheeta. Kashet joined the United Federation of Planets sometime before 2386. 

In the 20th century, the male leaders of Kashet were overthrown in a revolution after their use of chemical weapons caused a new ice age. This led to a rigid matriarchal society that continued through the 24th century.

Cities on Kashet were built inside large climate-controlled domes and overseen by governors selected from royal families. As late as 2275 (when the Federation made first contact with the Kasheeta) it was illegal in some cities to teach basic literacy to males.
