The state of Manipur conducted elections for the first time with voters above 18 years of age.
Explanation:
The right to vote that is given to every citizen above the age of 18 is called Universal Adult Franchise. It is based on the principle of equality.
Manipur held elections based on Universal Adult Franchise in June 1948, 2 years before the principle was introduced throughout India.
The elections were held by the then-Maharaja of Manipur, Bodhchandra Singh, to decide whether Manipur should be a constitutional monarchy after its accession to the Indian government.
