The Gonzaga dynasty ruled the Lombard Italian city-state Mantua from 1328 to 1708, first as a captaincy-general, then a margraviate/marquisate then finally a duchy/dukedom.

The uploaded image is one of several wall paintings by Andrea Mantegna (1431-1506) in the Camera degli Sposi (room of the spouses/bridal chamber) in the Ducal Palace of Mantua. Margrave/Marquis Ludovico Gonzaga III is on the left, seated and wearing a long red robe and red head gear (beret?).

Aloysius (archaic form of 'Louis') Gonzaga (1568-1591) was an early cadet saint of the Jesuits (Societas Jesuitis = Society of Jesus). He was born in the Duchy of Mantua and related to the ruling house of Gonzaga. At age 11 he and younger brother Rodolfo visited the court of the Duke of Mantua, where he was repulsed by its violence and frivolity, which in turn caused him to gravitate towards monasticism, in particular the then new Jesuit order. In the last year of his life at age 23, Aloysius, already afflicted with a diseased kidney since age 8, would care for plague victims in Rome and would himself succumb to the plague. Consequently he would become patron saint of the blind, Jesuit scholastics, young Christian students and more recently AIDS victims and their caregivers.

He is the dedicatee of Gonzaga University in Spokane, Washington and Gonzaga Collegiate Prep High School in Washington DC; both are Jesuit institutions.
