George III was the first Hanoverian to be born in Britain. Unlike his father and grandfather he had no interest in Hanover. He wanted to take a more active part in governing Britain, and in particular he wished to be free to choose his own ministers. As long as he worked with the small number of aristocrats from which the king's ministers were chosen, and who controlled Parliament, it did not seem as if he would have much difficulty.
Parliament still represented only a very small number of people. In the eighteenth century only house owners with a certain income had the right to vote. This was based on ownership of land worth-forty shillings a year in the counties, but the amount varied from town to town. As a result, while the mid-century population of Britain was almost eight million, there were fewer than 250,000 voters, 160,000 of them in the counties and 85,000 in the towns or "boroughs". Only 55 of the 200 boroughs had more than 500 voters. The others were controlled by a small number of very rich property owners, sometimes acting together as a "borough corporation". Each county and each borough sent two representatives to Parliament.
This meant that bargains could be made between the two most powerful groups of people in each "constituency", allowing the chosen representative of each group to be returned to Parliament.
