His father, Pierre d'Amboise, seigneur de Chaumont, was chamberlain to Charles VII and Louis XI and ambassador at Rome.
On arriving at manhood d'Amboise attached himself to the party of Louis, duc d'Orléans, in whose cause he suffered imprisonment at Corbeil, and on whose return to the royal favor he was elevated to the archbishopric of Narbonne, (June 18, 1482) in which the pope refused to confirm him; after some time he changed his see for that of Rouen (1493).
[1] In 1498 the duc d'Orléans mounted the throne as Louis XII, and d'Amboise was suddenly raised to the high position of cardinal (September 17, 1498) and prime minister.
He accompanied Louis and entered with him into Milan 6 October 1499; he was charged with organizing that province under French control, then returned to France in November.
Having the good fortune to serve a king who was both economical and just, he was able to diminish the imposts, to introduce order among the soldiery, and above all, by the ordinances of 1499, to improve the organization of justice.
d'Amboise had authorised the burning of butter instead of oil, which was scarce, in lamps during Lent, collecting monies of six deniers Tournois from each diocesan for this permission.
His body was removed to Rouen; and a magnificent tomb, on which he is represented kneeling in the attitude of prayer, was erected to his memory in the cathedral of that town.
