Step-by-step explanation:
The Sisters of Charity began their programs in the early 1800s. During this period, many women who had been involved in providing care during wartime continued their efforts in civilian life, forming organizations to assist the needy and sick. Notably, the Women's Charitable Benevolent Association was formed as the war neared its end to address such concerns, engaging in activities such as running soup kitchens and providing homes for returning soldiers.
Additionally, the Progressive Era of the early 1900s saw an expansion of social work, with numerous settlement houses opening to continue the work of aiding those in need. Amidst economic downturns and crises like the Great Depression, private charities and organizations were often the only support for many individuals, as government relief programs were limited or nonexistent.
