Abstract
One of the aspects of the Antonian cult, of purely portuguese origin, lies in the fact that Saint Anthony is given a prominent role in the military field, as a protector of the portuguese army. From the middle of the 17th century, this tradition began, which, with the support of the monarchy and military institutions, led to Saint Anthony being enlisted in the portuguese army, among which he distinguished himself, particularly in the fights against castilians and french. The prestigious military patents and insignia granted to him reflect the success of the military actions in which he was involved, contributing decisively to the defense of national sovereignty. From the 18th century onwards, traces of the military facet of Saint Anthony put at the service of the spanish crown are well known, especially in the fights against moors and french, and also as an important figure in the process of guaranteeing sovereignty.
