Saint Colette was born Nicole Boellet (or Boylet) in the village of Corbie, in the Picardy region of France. She was affectionately called Nicolette by her parents, which soon came to be shorted to Colette, by which name she is known.
She was a French abbess and the foundress of the Colettine Poor Clares, a reform branch of the Order of Saint Clare, better known as the Poor Clares.
In 1410, she opened her first monastery at Besançon, in an almost-abandoned house of Urbanist Poor Clares. From there, her reform spread to Auxonne (1412), to Poligny (1415), to Ghent (1412), to Heidelberg (1444), to Amiens, to Pont-à-Mousson in Lorraine, and to other communities of Poor Clares. During her lifetime 18 monasteries of her reform were founded. For the monasteries which followed her reform, she prescribed extreme poverty, going barefoot, and the observance of perpetual fasting and abstinence.
She is honored as a saint in the Catholic Church. Due to a number of miraculous events claimed during her life, she is venerated as a patron saint of women seeking to conceive, expectant mothers, and sick children.
