Title:
Edmund_Burke

Context:
The administration of Lord North (1770–1782) tried to defeat the colonist rebellion by military force. British and American forces clashed in 1775 and, in 1776, came the American Declaration of Independence. Burke was appalled by celebrations in Britain of the defeat of the Americans at New York and Pennsylvania. He claimed the English national character was being changed by this authoritarianism. Burke wrote: "As to the good people of England, they seem to partake every day more and more of the Character of that administration which they have been induced to tolerate. I am satisfied, that within a few years there has been a great Change in the National Character. We seem no longer that eager, inquisitive, jealous, fiery people, which we have been formerly".

Question:
When did Lord North leave office?

1782
