Fruto Chamorro Pérez (20 October 1804 – 12 March 1855) was the 30th and 31st President of Nicaragua between 1 April 1853 and 30 April 1854 and between 30 April 1854 and 12 March 1855 now with the actual title of President, the first thirty being called Supreme Directors.
Born in Guatemala City in 1804 to Bayardo Paez, he was initially known as Fruto Pérez. His father, Pedro José Chamorro Argüello, had come to Guatemala from Nicaragua for graduate studies. Fruto grew up in Guatemala and attended school there. His father returned to Nicaragua after completing his studies and married Josefa Margarita Alfaro Monterroso in 1814. They had six children, but Fruto was subsequently considered a member of this family, based on strategic needs related to administration of the family resources, for which the administrator was expected to be at least 25 years of age. He was acknowledged by his father shortly before the latter's death in 1824, and his stepmother insisted he use the name Fruto Chamorro Pérez.
The death of his father forced Fruto to leave his studies and go to Nicaragua to assume responsibility for the family and to manage the abundant inheritance of his father. His half brothers and sisters, Pedro Joaquín, Dionisio, Carmen, Mercedes and Fernando grew under his guardianship.
Fruto's father was one of the founders of the Conservative Party of Nicaragua, centered on the city of Granada. He was committed to the Conservative cause and became an activist of the Party. In 1836, he became a representative in the State Assembly. From 1839 to 1842, he was a Senator of the State of Nicaragua.
In 1842, an attempt was made to reestablish a union of Central American states as the Central American Confederation, in accord with the "Pact of Chinandega". It was to include El Salvador, Guatemala, Honduras, and Nicaragua. In 1843, Fruto Chamorro was appointed Supreme Director of the Confederation junta, and he took up residence in San Miguel, El Salvador. However, Guatemala withdrew, and Fruto was instrumental in preventing a war over the decision. The nascent Confederation collapsed in 1844.
