I understand, from my readings in Indian history, that laws had to be passed by the Raj (and forced on some of the Princely States), concerning the age of marriage and the age of consent. This seems to have been a particular issue with respect to Royal or Princely marriages.
Unfortunately India’s ancient Vedic tradition had been messed with by hundreds of years of Muslim atrocity and invasion by the time the British decided to take their share of booty.
