Tipu Sultan is probably the Muhammadan monarch who most systematically engaged in the work of forcible conversion.... early in 1789 Tipu Sultan prepared to enforce his proclamation (for conversion of Hindus) with an army of more than twenty thousand men.... Thousands of Hindus were accordingly circumcised and made to eat beef... most of the Brahmans and Nayars who had been forcibly converted subsequently disowned their new religion.
