Hoysalas were a kingdom in the south which rose to power with the decline of the Chalukyas. In order to encourage agriculture, the Hoysalas built innumerable lakes like the Shanti Sagara, Ballalaraya Samudra,Vishnu Samudra etc. In the cities, there used to be guilds among the people following different occupations. Land revenue was the main source of income for the kingdom. A unique feature of this society was that the king used to have a special army of guards called garuda. When the king died, these guards would also sacrifice their lives. Agraharas, mathas and temples were centres of education.
