Mariano Trías y Closas (October 12 1868 – February 22, 1914) is considered to be, de facto, the first Philippine Vice President of that revolutionary government established at the Tejeros Convention - an assembly of Philippine revolutionary leaders that elected officials of the revolutionary movement against Spain. When that assembly broke into factions, a truce signed by the group known as the Pact of Biak na Bato also recognized the elected officials and Trias as the Vice President of Emilio Aguinaldo who is also considered to be the First Philippine President. With the proclamation of the Malolos Constitution, the First Philippine Republic was born. Under this Aguinaldo administration, Trias served in the cabinet as the Minister of War and Finanace.
He was married to María Concepción Ferrer with whom he had eight children.
Early life and career
Mariano was the fifth of the nine children of Don Balbino Trias, a cabeza de barangay and justice of the peace during the Spanish regime who, after his term of office, become a landowner-farmer. His mother was Gabriela Closas.
He had primary schooling under the tutorship of Eusebio Chaves and Cipriano Gonzales, both local school teachers. Later, he was sent to Manila and enrolled at San Juan de Letran for his Bachelor of Arts, then to University of Santo Tomas for his course in Medicine, which he was unable to finish as he returned home to help his parents manage the farm holdings.
Before the revolution in August 1896, he joined the Katipunan and became an active propagandist of the society in the towns of Silang and Kawit. In the election of the Katipunan popular council, which was organized by the Sangguniang Balangay of Mapagtiis, he was named fiscal.
When two councils of the Katipunan revolutionist came into existence (namely, the Sangguniang Bayang Magdiwang and the Sangguniang Bayang Magdalo), both factions set up their respective councils of leaders. Trias became the Minister of Justice and grace of the Magdiwang group.
On March 22, 1897, a second assembly of Katipunan leaders from both factions was held, this time at Tejeros, near the coast, in the heart of the Magdiwang territory. This happened while Aguinaldo and the Magdalo factions were desperately trying to stop the advancing of the Lachambre soldiers. After a stormy debate, it was agreed to set up a new government, replacing that of the Katipunan. Nine positions were to be filled. By secret ballot, Emilio Aguinaldo who was absent, defending Imus against the forthcoming attack by Governor Lachambre was elected president and Mariano Trías as vice president. Bonifacio was defeated for both positions.
At the revolutionary assembly convoked by Aguinaldo in Naic, Cavite after Easter Sunday of 1897, Trías was again chosen as vice president of the new government. On November 1, 1897, the Biac-na-Bato Republic was established. Emilio Aguinaldo was president and Trías was vice president.
After the abolition of the dictatorial government and the establishment of the revolutionary government, he was appointed on July 15, 1898 as Secretary of Finance and continued in this office after the transfer of seat of the government to Malolos. In the Paterno Cabinet, which succeeded the Mabini Cabinet, he held the position of secretary of war. After the revolutionary government forces were practically dispersed in Central Luzon, he was named commanding general of Southern Luzon. He directed guerrilla offensive moves in Cavite.
He figured in a series of furious skirmishes with the troops of General Wheaton in January 1900 when he held the defense of Cavite until his men where finally dispersed.
General Trías set free all the Spanish prisoners under his command in May 1900.
Nine days after the capture of Aguinaldo, General Trías, accompanied by Severino de las Alas, former Secretary of the Interior, Ladislao Diwa, ex- governor of Cavite, two colonels, two lieutenant colonels and a number of majors, captains, and lieutenants, and some hundreds of soldiers with guns, voluntarily surrendered in Santa Cruz de Malabon, Cavite to General Baldwin on May 13, 1901.
Trías was the founder of the Nacionalista Party chapter in Cavite. He supported the candidacy of Rafael Palma as assemblyman, representing the lone district of Cavite in 1907. In the general elections of 1912, Trías was responsible for the election of Antero S. Soriano and Florentino Joya as Governor and Representative, respectively, of Cavite. 
He sailed to the United States as member of the honorary board of Filipino commissioners to the Louisiana Purchase Exposition in 1904. After his term of office, he engaged in agricultural activities, but this was a brief respite from politics. He was the acting governor of Cavite when he died of appendectomy at the Philippine General Hospital on February 22, 1914. He was buried in Manila. His remains were transferred to his hometown in 1923.
