Fernando Vázquez de Menchaca (1512–1569) was a Spanish jurist.
Fernando Vázquez de Menchaca was probably born in 1512 in Valladolid. [1] His family members included judges and administrators. He studied law at the universities of Vallodolid and Salamanca, graduating from the latter about 1548. [2] [1] Menchaca held various positions as a judge and bureaucrat, including at the court of Philip II of Spain. [3] Menchaca was a member of the Council of the Indies and the Order of Santiago. He died in 1569 in Seville. [4] He was a hidalgo. [2]
In his treatise Controversiarum illustrium aliarumque usu frequentium libri tres (Three books of famous and other controversies frequently occurring in practice), [1] likely first published in Venice in 1564, [1] Menchaca argued that political authority derives from the consent of the governed. Because people form societies by "natural inclination", according to Menchaca, political authority is an aspect of natural law. [5] Menchaca held that persons have natural rights including liberty and equality and endorsed a version of the social contract theory. [6] In this respect, Menchaca thought that domestic society and international society were on a par: both were based on "pacts and treaties". [7] Further, since people create society "for their own utility", Menchaca argued that the people had an inalienable power to control their rulers. [8]
Mencha is considered a member of the School of Salamanca. [1] He published six treatises between 1559 and 1564. [9] His thought influenced Hugo Grotius and Samuel von Pufendorf. [5] [10] Scholar Salvador Rus Rufino identifies Menchaca as part of the tradition of Catholic humanism. [11]
