Dom Maria Evaristo Miguel, a Portuguese prince, born in Lisbon, Oct. 26, 1802, died at Brombach, Baden, Nov. 14, 1866. He was the third son of John VI. of Portugal and Car-lotta Joachima, a daughter of Charles IV. of Spain, and spent his early life with his parent- in Brazil returning with the royal family to Portugal in 1821. When his elder brother Dom Pedro became emperor of Brazil, and his father established a constitutional monarchy in Portugal (1822), Dom Miguel, instigated by his mother, and aided by several of the nobility and clergy and by a large part of the troops, formed plots against the new constitution. He rebelled in 1823, and in 1824, with his mother, was expelled from the coun-trv. He went first to Paris, and then to Vienna. His father died on March 10, 1826, and his sister Isabella Maria was for a short time resent of Portugal. Dom Pedro relinquished the throne of Portugal (May 2) to his daughter. Dona Maria (afterward Dona Maria II. da Gloria), then in her seventh year, offering her hand in marriage to her uncle Dom Miguel, who was appointed to the regency July 3,1827, and took the oath to maintain the constitution (Feb. 26, 1828). Soon afterward he defeated the garrisons of Oporto and other places which declared for Dom Pedro, convened new cor-te3, imprisoned or exiled the legislators who were likely to oppose him, and was proclaimed absolute king on June 25. He consolidated his power by the most despotic methods.

Those implicated in the Oporto insurrection were mercilessly punished, and the prisons of the country tilled with liberals; an expedition was sent against Madeira and the Azores, whose inhabitants had refused to acknowledge him, and the islands were subdued with the exception of Terceira in the Azores. Dom Miguel's cruel administration soon became odious to the people. Terceira continued to hold out against him, and the leaders of the constitutional party gathered there, established a regency in the name of Dona Maria, and collected a fleet and army with which Dom Pedro, who had abdicated the throne of Brazil (1831), sailed in June. 1832, for Oporto, which betook without bloodshed. In the following year his fleet, commanded by Sir Charles John Napier, destroyed that of Dom Miguel, and the army ad-vanced to Lisbon, which declared unanimously for Dona Maria. Dom Miguel was abandoned by most of his followers, and in May, 1834, concluded at Evora a convention by which he agreed to quit Portugal. He went to Genoa and to Rome, and subsequently spent several years in London, where he was noted for debauchery.

In 1851 he married the German princess Adelheid von Lowenstein-Wertheim-Rosenberg, by whom he bad a son (Miguel, born id 1853) and four daughters.
