Mendicant orders refers primarily to certain Christian religious orders that have adopted a lifestyle of poverty, travelling, and living in urban areas for purposes of preaching, evangelization, and ministry, especially to the poor. At their foundation these orders rejected the previously established monastic model of living in one stable, isolated community where members worked at a trade and owned property in common, including land, buildings and other wealth. By contrast, the mendicants avoided owning property, did not work at a trade, and embraced a poor, often lifestyle. They depended for their survival on the goodwill of the people to whom they preached.
The term "mendicant" is also used with reference to some non-Christian religions to denote holy persons committed to an ascetic lifestyle, which may include members of religious orders and individual holy persons.
What is called the mendicant movement in Church history arose primarily in the 13th century in Western Europe. Until that time the monks of Europe worked at their trade in their monastery. Renouncing personal property, they owned all things in common as a community after the example of chapters 2 and 4 of the Acts of the Apostles.
With the rise of Western monasticism, monasteries attracted not only individuals aspiring to become monks and nuns, but also property, buildings and riches. The idea that Christ came down to earth poor and that the true Church must be the church of the poor clashed with this image. The desire for true Christian authenticity was thus seen by some to contrast to the reality of the empirical Church.
The twelfth century saw great changes in western Europe. As commerce revived, urban centers arose and with them an urban middle class. New directions in spirituality were called for. Ecclesiastical reform became a major theme of the cultural revival of this era. In response to this crisis, there emerged the new mendicant orders founded by Francis of Assisi (c.1181-1226) and Dominic Guzman (c.1170–1221).
The mendicant friars were bound by a vow of poverty and dedication to an ascetic way of life, renouncing property and travelling the world to preach. Their survival was dependent upon the good will and material support of their listeners. It was this way of life that gave them their name, "mendicant", derived from the Latin mendicare, meaning "to beg".
The mendicant movement had started in France and Italy and became popular in the poorer towns and cities of Europe at the beginning of the thirteenth century. The refusal of the mendicants to own property and therefore to pay taxes was seen as threatening the stability of the established Church which was then planning a crusade, to be financed by tithes. For this and other reasons some mendicant orders were officially suppressed by Pope Gregory X at the Second Council of Lyon in 1274 and others were reformed, so as to be capable of contributing funds or men to support the war effort.
