From the return of Francis and his eleven companions from Rome to Assisi in 1209 or 1210, their work prospered in a wonderful manner. The effect of their preaching, and their example and their work among the poor, made itself felt throughout Umbria and brought about a great religious revival. Great numbers came to join the new order which responded so admirably to the needs of the time. In 1212 Francis invested St Clara (q.v.) with the Franciscan habit, and so instituted the "Second Order," that of the nuns. As the friars became more and more numerous their missionary labours extended wider and wider, spreading first over Italy, and then to other countries. Francis himself set out, probably in 1212, for the Holy Land to preach the Gospel to the Saracens, but he was shipwrecked and had to return. A year or two later he went into Spain to preach to the Moors, but had again to return without accomplishing his object (1215 probably). After another period of preaching in Italy and watching over the development of the order, Francis once again set out for the East (1219). This time he was successful; he made his way to Egypt, where the crusaders were besieging Damietta, got himself taken prisoner and was led before the sultan, to whom he openly preached the Gospel. The sultan sent him back to the Christian camp, and he passed on to the Holy Land. Here he remained until September 1220. During his absence were manifested the beginnings of the troubles in the order that were to attain to such magnitude after his death. The circumstances under which, at an extraordinary general chapter convoked by him shortly after his return, he resigned the office of minister-general (September 1220) are explained in the article FRANCISCANS: here, as illustrating the spirit of the man, it is in place to cite the words in which his abdication was couched: "Lord, I give Thee back this family which Thou didst entrust to me. Thou knowest, most sweet Jesus, that I have no more the power and the qualities to continue to take care of it. I entrust it, therefore, to the ministers. Let them be responsible before Thee at the Day of Judgment, if any brother by their negligence, or their bad example, or by a too severe punishment, shall go astray." These words seem to contain the mere truth: Francis's peculiar religious genius was probably not adapted for the government of an enormous society spread over the world, as the Friars Minor had now become. The chief works of the next years were the revision and final redaction of the Rule and the formation or organization of the "Third Order" or "Brothers and Sisters of Penance," a vast confraternity of lay men and women who tried to carry out, without withdrawing from the world, the fundamental principles of Franciscan life (see TERTIARIES).
