Urs had practically retired from politics when the first Congress split took place in 1969, and the Syndicate formed the Congress (O) ('O'for "Organization") while Indira Gandhi formed the Congress (R). The Congress (O), under S. Nijalingappa, Veerendra Patil, Ramakrishna Hegde and Deve Gowda dominated Karnataka electorally and had a majority in the state assembly, but Urs declined an invitation to join it. Instead, he agreed to lead the Congress (R) in the state and helped win all the 27 seats at the 1971 Lok Sabha elections and majority in the 1972 legislative assembly elections. Under his leadership Congress(R) won 165/216 seats, thus garnering more than 75% of the seats. Congress(O) came a distant second with 24 seats. Independents won 20 seats. CPI won 3 while BJS, the earlier avatar of BJP stood second in 16 seats, winning none. He was chief minister of Karnataka for the full term of the assembly from 1972 to December 1977. In January 1978, he joined Congress (I) as Mrs Gandhi split the party yet again. The new party won the assembly elections in February 1978 and Urs was appointed Chief Minister. But in 1979, he left Congress(I) following differences with Indira Gandhi, and joined the other Congress faction, Congress(S). He continued to be CM as many MLAs joined him. The other Congress faction was even known as Congress(Urs) briefly when he became its president. But in the 1980 Lok Sabha elections, his party won just one seat in Karnataka. Most MLAs in his camp deserted him to re-join Congress(I) and Gundu Rao became Chief Minister in January 1980. Urs then formed the Karnataka Kranti Ranga in 1982, a few months before his death.
