Kollegala is one of the major taluks in the Chamrajnagar District. Kollegala is well known for its silk industry which attracts traders from all over the state.
Until 1956, Kollegala was part of the Coimbatore district of the Madras Presidency.
The States Reorganization Act of 1956 moved Kollegala to Karnataka primarily organising it along linguistic lines. Kollegala is the name derived from the names of two hermits namely 'Kauhala' and 'Galava' who were believed to be instrumental in the development of Kollegala.
Kollegala, also called ""Silk City"", is famous for its hand loom silk saree industry. Kollegala is one of the larger taluks in Karnataka and was previously the largest. Plans are underway to divide Kollegala, making Hanur the capital of the new taluk in the Chamrajanagar district.
