Understanding the Integration of Rajasthan and Mewar's Role

The integration of the various princely states of Rajputana into the state of Rajasthan was a complex process that occurred in several phases. This question specifically asks about the state that joined during the third phase, leading to the formation of the United Rajasthan.

Phases of Rajasthan Integration

The integration process involved several stages. Let's briefly look at the early phases:

• First Phase (Matsya Union): Formed on March 18, 1948, including Alwar, Bharatpur, Dholpur, and Karauli.
• Second Phase (Rajasthan Union): Formed on March 25, 1948, joining nine states: Banswara, Bundi, Dungarpur, Jhalawar, Kishangarh, Kota, Pratapgarh, Shahpura, and Tonk.

The Third Phase: United Rajasthan

The third phase of integration took place on April 18, 1948. In this crucial phase, the prominent state of Mewar (Udaipur) was integrated into the Rajasthan Union formed in the second phase. The inclusion of Mewar significantly increased the size and political importance of the newly formed entity, which was then named the United Rajasthan (Samyukta Rajasthan).

Therefore, the state of Rajputana that joined in the third phase of the Integration of Rajasthan in the United Rajasthan was Mewar.

Analyzing Other Options

Let's consider why the other options are not correct:

• Marwar (Jodhpur), Jaisalmer, and Bikaner: These large states, along with Jaipur, joined the United Rajasthan in the fourth phase, forming the 'Greater Rajasthan' (Vrahat Rajasthan) on March 30, 1949.

Based on the phases of integration, Mewar was the state that merged into the Rajasthan Union in the third phase to form the United Rajasthan.
