Polling began at 8 a.m. Sunday for the 200-seat Rajasthan assembly, an official said.
Around 40 million people are eligible to vote. Ballotting will take place in 199 constituencies as the election has been postponed in Churu to Dec 13 following the death of a Bahujan Samaj Party candidate.
A total of 2,087 candidates are in the fray. Votes will be counted Dec 8.
In the outgoing house, Congress holds 102 seats and the Bharatiya Janata Party 79.
