King João VI (1816-1826)

King Joao and the royal family were residing in Brasil since 1807. The consequent spread of dissatisfaction resulted in the peaceful revolution of 1820, and the proclamation of a constitutional government, to which he swore fidelity on his return to Portugal in 1821.

In the same year, and again in 1823, he had to suppress a rebellion led by his son Dom Miguel, whom he ultimately was compelled to banish in 1824. Meanwhile his elder son, Dom Pedro, declared Brazilian independence from Portugal in 1822. Joao refused to assent to this devolution until 1825, when he restored Pedro to the succession in the belief that Brazil and Portugal would be reunited in a dual monarchy federation after his own death.

King Joao died in 1826, and was succeeded by Pedro (as King Pedro IV).
