Explanation:

 The earlier politics were dominated by the Congress party. The main opposition party was the Bharatiya Jansangh, headed by Rajasthan's most popular leader Bhairon Singh Shekhawat and the Swatantra party headed by former rulers of Rajasthan. The Congress rule was untouched till the year 1962. But in 1967, Jansangh headed by Shekhawat and Swatantra party headed by Rajmata Gayatri Devi of Jaipur reached the majority point, but couldn't form a government. In 1972, the Congress won a landslide victory following the victory in the 1971 war. But after the declaration of emergency, Shekhawat became immensely popular, especially after he was forced to be arrested and was sent to Rohtak Jail in Haryana. As soon as the emergency was lifted, a joint opposition Janta Party won a thundering landslide victory winning 151 of the 200 seats. Shekhawat became the Chief Minister.
