On the other hand, Massachusetts Bay was the first colony to legalize slavery with provision 91 of the Massachusetts Body of Liberties which developed protections for people unable to perform public service. Another law was developed to protect married women, children, and people with mental disabilities from making financial decisions. Colonial law differentiated among types of mental disabilities, classifying them as "distracted persons," "idiots," and "lunaticks". In 1693, "poor laws" enabled communities to use the estates of people with disabilities to defer the cost of community support of those individuals. Many of these laws remained until the American Revolution.
