Victoria's advisors threatened her with being declared insane. Although she was only 1 when her grandfather George III died, she was aware that he had been declared insane and his son (her uncle) ruled as Prince Regent for 9 years from 1811 to 1820. Therefore she knew that it was possible for her advisors to carry through on their threat.
