LABEZARES, Guido de (lah-bay-thah'-rets), Spanish adventurer, born in Bilboa in 1510; died in Manila in 1580. He went in early life to New Spain, and accompanied Ruy Lopez de Villalobos in 1542 in his unfortunate expedition to the Spice islands, which he was not able to leave till 1549. He returned to the city of Mexico, and when the viceroy, Luis de Velasco, was preparing an expedition to conquer and explore Florida, was given command of a vessel with several pilots, which was sent in advance to explore the coast for the most favorable landing-points. He sailed on 3 September, 1558, from San Juan de Ulua, and discovered in latitude 29º 30' N. a favorable bay, which he named Filipina; but sailing for some distance along the coast and not finding a better port, he returned on 14 December. He wrote a narrative of his voyage, which greatly aided Luna de Arellano (q. v.) in his expedition of the next year, in which he was accompanied by Labezares. The latter returned to Mexico when Legaspi (q. v.) and Andres de Urdaneta were preparing their expedition for the conquest of the Philippine islands. He obtained the post of treasurer of the expedition, and sailed with the same, 21 November, 1564, from the port of Navidad. He accompanied Legaspi during the conquest, and after the latter's death was called to the chief command of the Philippines. Notwithstanding his advanced age, he governed the islands wisely, conquered the provinces of Pangasinan and Ilocos, and forced the Chinese general of the corsair "Li-Ma-Hon " to surrender Manila, which he fortified. In August, 1575, the newly appointed governor-general, Dr. Francisco de Saude, arrived, and Labezares surrendered the government. His official acts were approved, and till his death he retained the honorary title and salary of lieutenant-governor. He wrote a narrative of his two voyages to Florida, and one of the conquest of the Philippines, published by order of the Spanish government (Madrid, 1578).
