The sixteenth century was a crucial period in the history of French monasticism. In addition to the causes of a general decline throughout Europe, in France two peculiar developments precipitated a nearly fatal collapse of monastic establishments. One was the commendatory system that spread over the whole country following the Concordat of Bologna in 1516. Royally appointed commendatory abbots, whose only concern was the collection of their share of monastic income, contributed much to the moral and material decline of the institutions supposedly under their care. The other and even more devastating calamity was the series of religious and civil wars during the second half of the century that resulted in the pillage and partial or total destruction of hundreds of monasteries.
