On 8 January 1772, after the revolt against Struensee, Frederick's 18-year-old half-uncle Hereditary Prince Frederick was made regent. The real power, however, was held by Hereditary Prince Frederick's mother (Crown Prince Frederick's step-grandmother), Queen Dowager Juliana Maria, aided by Ove Høegh-Guldberg. Frederick was raised under the supervision of Margrethe Marie Thomasine Numsen. Finally, on 14 April 1784, the Crown Prince Frederick was declared of legal majority; he proceeded to seize and exercise the full powers of the regency, dismissing the ministers loyal to the Queen Dowager. It is said that during the coup, he engaged in a fistfight with his half-uncle over the regency. He continued as regent of Denmark under his father's name until the latter's death in 1808.
