The Indian Council Act of 1909, also known as the Morley-Minto Reforms, introduced separate electorates for Muslims in the Imperial Legislative Assembly elections.
Separate electorates meant that Muslims could vote only for Muslim candidates in certain constituencies, and similarly, Hindus could vote for Hindu candidates. This system deepened the communal divide in Indian politics.
The reforms also allowed for the expansion of the Legislative Councils, enabling limited participation of Indians in governance, though the power remained firmly in British hands.
