Baldomero Aguinaldo y Baloy (February 27, 1869—February 4, 1915) was a leader of the Philippine Revolution. He was the first cousin of Emilio Aguinaldo, the first president of the Philippines, as well as the great grandfather of Cesar Virata, a former prime minister in the 1980s.
Baldomero Aguinaldo was born in Kawit, Cavite. He studied law at the University of Santo Tomas in Manila and was still a law student during the outbreak of the Philippine Revolution. He obtained a law degree, but failed to take the bar examination. Unable to practice law, he became a farmer.
Shortly after the outbreak of the revolution, Aguinaldo organized, along with his cousin Emilio, the Magdalo faction of the Katipunan in Kawit. He became president of the council. In the early days of hostilities, he always stayed at the side of his cousin Emilio. He fought in several bloody battles. He also led the Magdalo faction to the Katipunan which had it's headquarters in Kawit,Cavite.
Aguinaldo's knowledge of the law and administrative procedures made him a valuable asset to the revolutionary government. He was appointed to several cabinet positions, and was a signer of two important documents: The Biak-na-bato Constitution, and the Pact of Biak-na-Bato.
During the Philippine-American War, Aguinaldo fought again, becoming commanding general of the revolutionary forces in the southern Luzon provinces. When hostilities ended in 1901, he retired to private life.
Aguinaldo died in Manila of heart failure and rheumatism at the age of 46.
