It was not until the 15th century that there developed single well-ordered religious communities with solemn vows and a common head. In the 15th century there were numerous independent male congregations of regular tertiaries with the three vows in Italy, Sicily, Dalmatia, Spain, Portugal, France, Germany, and in the Netherlands. The Obregonians, or the "Minim Congregation of Poor Brothers Infirmarians", were a small Spanish Roman Catholic congregation of men dedicated to the nursing care of the sick. The congregation ceased to exist around the time of the Peninsular War.
