The Balinese caste system is a system of social organization based on the
Indian caste system. However, India's caste system was far more complicated
than Bali's, and there are only four Balinese castes.

The four castes of Bali are:
-Sundras - peasants making up more than 90% of Bali's population
-Wesias - the warrior caste, it also included some nobility and
merchants
-Satrias - the caste of kings
-Pedanas - holy men and priests

Each of the four castes had their own separate dialect of the Balinese
language. There was a fifth dialect that was used to speak to people of
whose caste was unknown. Over the past few years, these differences in
dialect have almost disappeared as the caste system has lost power.
