Iglesias, Miguel, 1822-1901, president of Peru (1881-85). A general, he fought in the war with Chile (see Pacific, War of the), distinguishing himself in the defense (1881) of Lima. Because the government failed to meet Chilean demands, Iglesias, supported by Chile, assumed the presidency and accepted the harsh terms of the Treaty of Ancón (1883). Many Peruvians refused to acknowledge him as president, and a revolution led by Cáceres was successful. Defeated in the ensuing election, Iglesias left the country.

Iglesias, town (1991 pop. 30,134), SW Sardinia, Italy. The zinc and lead mines of the region have been famous since the 13th cent. The influence of Pisa, which controlled Iglesias in the Middle Ages, is apparent in the Romanesque cathedral (14th-15th cent.) and the medieval castle.
