1911 Encyclopædia Britannica/John VI. of Portugal
JOHN VI. (1769–1826), king of Portugal, was born at Lisbon on the 13th of May 1769, and received the title of prince of Brazil in 1788. In 1792 he assumed the reins of government in name of his mother Queen Mary I., who had become insane. He had been brought up in an ecclesiastical atmosphere, and, being naturally of a somewhat weak and helpless character, was but ill adapted for the responsibilities he was thus called on to undertake. In 1799 he assumed the title of regent, which he retained until his mother’s death in 1816. (For the political history of his regency, see Portugal.) In 1816 he was recognized as king of Portugal but he continued to reside in Brazil; 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 1822. 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. He died at Lisbon on the 26th of March 1826, and was succeeded by Pedro IV.
