Juan de Mariana SJ (25 September 1536 – 17 February 1624), was a Spanish Jesuit priest, Scholastic, historian, and member of the Monarchomachs.
[2] In 1561, he went to teach theology in Rome, reckoning among his pupils Robert Bellarmine, afterwards cardinal; then passed into Sicily; and in 1569 he was sent to Paris, where his expositions of the writings of Thomas Aquinas attracted large audiences.
In 1574, owing to ill health, he obtained permission to return to Spain; the rest of his life being passed at the Jesuits' house in Toledo in vigorous literary activity.
[2] Juan de Mariana's great work, Historiae de rebus Hispaniae, first appeared in twenty books at Toledo in 1592; ten books were subsequently added (1605), bringing the work down to the accession of Charles V in 1519, and in a still later abstract of events the author completed it to the accession of Philip IV in 1621.
[3] In its sixth chapter the question whether it is lawful to overthrow a tyrant is freely discussed and answered in the affirmative, a circumstance which brought much odium upon the Jesuits, especially after the assassination of Henry IV of France, in 1610.
