nicknamed "the Clement", was King of the United Kingdom of Portugal, Brazil and the Algarves from 1816 to 1822. Although the United Kingdom over which he ruled ceased to exist de facto beginning in 1822, he remained its monarch de jure between 1822 and 1825. After the recognition of Brazilian independence under the Treaty of Rio de Janeiro of 1825, he continued as King of Portugal and the Algarves until his death in 1826. Under the same treaty, he also became titular Emperor of Brazil for life, while his son, Emperor Pedro I, was both de facto and de jure the monarch of the newly-independent country.
