Throughout the fourteenth century, the regular tertiaries of both sexes had in the most cases no common organization; only in the following century we can observe single well-ordered religious communities with solemn vows and a common head. Pope Martin V submitted in 1428 all tertiaries, regular and secular, to the direction of the Minister-General of the Friars Minor (Bull. Franc., VII, 715), but this disposition was soon revoked by his successor Pope Eugene IV. We meet thus in the same fifteenth century with numerous independent male congregations of regular tertiaries with the three vows in Italy, Sicily, Dalmatia, Spain, Portugal, France, Germany, and in the Netherlands. Contemporaneously there existed sister congregations of the Third Order with solemn vows, for instance, the Grey sisters of the Third Order, serving in hospitals, spread in France and the Netherlands. Leo X, to introduce uniformity into the numerous congregations, gave in 1521 a new form to the rule, now in ten chapters, retaining of the rule as published by Nicholas IV all that could serve the purpose, adding new points, especially the three solemn vows, and insisting on subjection to the First Order of St. Francis. For this last disposition the Rule of Leo X met with resistance, and never was accepted by some congregations, whilst it serves till the present day as the basis of the constitutions of many later congregations, especially of numerous communities of sisters.
