The Kurtzen were a pale, hairless, humanoid species from the planet Bakura. They were the only sentients native to the world; few in number, they became a minority when Human settlers arrived in 150 BBY. Kurtzen suffered from a degenerative genetic disorder that limited their population growth. Although medicine provided by the Human settlers helped them overcome the disease, Kurtzen comprised only five percent of Bakura's population by 4 ABY. Despite this, it was unusual for more than two children in a family to reach adulthood. Kurtzen society was divided into tribes and clans.
