What was the outcome of the merger of Manipur with India?

The unilateral decision of the merger led to resentment among the people of Manipur.

Manipur was a princely state with its own monarch, Maharaja Bodhchandra Singh, and a distinct political and administrative system.
It enjoyed a measure of autonomy under British colonial rule.
Maharaja Bodhachandra Singh of Manipur signed the Instrument of Accession with the Indian government shortly before Independence.
The agreement ensured that Manipur would maintain its internal autonomy.
In response to public opinion, elections were held in Manipur in June 1948, establishing a constitutional monarchy.
Manipur became the first part of India to hold elections based on ‘Universal Adult Franchise’.
The issue of the merger with India sparked sharp differences in the Legislative Assembly of Manipur.
While the state Congress supported the merger, other political parties opposed it.
The Government of India exerted pressure on the Maharaja to sign a Merger Agreement in September 1949 without consulting the popularly elected Legislative Assembly.
The unilateral decision of the merger caused anger and resentment among the people of Manipur which is felt till today
After the merger, Manipur initially became a Union Territory of India, directly administered by the central government.
This arrangement continued until 1972 when Manipur attained full statehood within the Indian Union
