Colonel Joaquín de San Martín y Ulloa (sometimes Joaquín San Martín) (1770 in Comayagua, Honduras – November 29, 1854 in Department of Chalatenango) was a Salvadoran military officer and politician who was twice chief of state of the State of El Salvador, within the Federal Republic of Central America (1832 and 1833–34).
Joaquín de San Martín[1] was a lieutenant of dragoons in Yoro and an official in the governments of Tegucigalpa and Nacaome.
With the aid of Captain Ramón Belloso and his company, San Martín also suppressed the hordes of thieves dominating the country, many of whom had tried to join with Aquino to contest governmental authority.
In March 1833, General Francisco Morazán joined with rebel forces against San Martín.
Colonel San Martín distinguished himself as a defender of the law during the tragic days of September 1841, when General Francisco Malespín staged a coup d'état and overthrew the legal president, Antonio José Cañas.
