The Ganden Podrang was the government system that ruled Central Tibet, in one form or another, from 1642 to 1959. Headed by the Dalai Lamas, the Ganden Podrang had a dual system that included both powerful Geluk monastic officials and secular members of the Central Tibetan noble families. From the eighteenth century onward, the Ganden Podrang had a central governing council called the “kashag,” or “parliament.”
