Monarchs had an incentive to take mistresses in that they generally made dynastic marriages of convenience, and there was often little love in them. Beyond the physical relationship, the royal mistress would often exercise a profound influence over the King, extending even to affairs of state.William IV was the last King and penultimate monarch of Britain's House of Hanover and his reign saw several reforms, not least the abolishment of slavery in almost all of the British Empire. The King cohabited with his mistress, Dorothea Jordan (see lot XXX), for twenty years and fathered ten illegitimate children with her.
