From Wikipedia - George III
Although George's accession was at first welcomed by politicians of all parties, the first years of George's reign were marked by political instability, largely generated as a result of disagreements over the Seven Years' War. George was perceived as favouring Tory ministers, which led to his denunciation by the Whigs as an autocrat. On George's accession, the Crown lands produced relatively little income; most revenue was generated through taxes and excise duties. George surrendered the Crown Estate to Parliamentary control in return for a Civil List annuity for the support of his household and the expenses of Civil Government. are disputed by historians who say such claims "rest on nothing but falsehoods put out by disgruntled opposition". Debts amounting to over £3 million over the course of George's reign were paid by Parliament, and the Civil List annuity was increased from time to time.[ Claims that George used the income to reward supporters with bribes and gifts
