Sisters of Charity form part of many religious communities. The first of these, the Daughters of Charity, was founded in 1633 by Vincent de Paul and dedicated itself to the care of the sick poor. Since then, many similar organizations have sprung up across the world. These all-female associations take on a broad range of humanitarian causes, focusing especially on the poor and vulnerable. They are involved in the founding of hospitals, orphanages and educational institutions, and they engage in a good deal of outreach work.
