Distinct from monks, who live a cloistered, contemplative life and sometimes engage in ministry to those from outside the monastery, canons devote themselves to public ministry of liturgy and sacraments for those who visit their churches. Historically, monastic life was by its nature lay, but canonical life was essentially clerical. Mendicant orders Around the 13th century during the rise of the medieval towns and cities the mendicant orders developed. While the monastic foundations were rural institutions marked by a retreat from secular society, the mendicants were urban foundations organized to engage secular city life and to meet some of its needs such as education and service to the poor.

The number of these congregations increased further in the upheavals brought by the French Revolution and subsequent Napoleonic invasions of other Catholic countries, depriving thousands of monks and nuns of the income that their communities held because of inheritances and forcing them to find a new way of living their religious life.

It was founded in the wake of the Protestant Reformation, introducing several innovations designed to meet the demands of the 16th century crisis.
