The International Confederation of the Society of Saint Vincent de Paul traces to a single meeting room in Paris in 1833, where the journalist Emmanuel Bailly and a group of young Catholic university students, among them Frederic Ozanam, organized what they called a Conference of Charity: a small circle committed to visiting the poor in their own homes rather than administering charity from a distance. In 1835 the growing network of conferences took the name it carries today, honoring Vincent de Paul as its patron. A decade after the first conference met, in 1845, the Holy See formally recognized the Society in a brief issued by Pope Gregory XVI, and conferences continued spreading well beyond France through the rest of the nineteenth century.
As conferences multiplied across different countries, the Society organized itself in layers rather than as one flat membership. Local conferences, still the grassroots unit and still called by that name, grouped into national councils as the Society took root in each country; the United States Society, for instance, was established in St. Louis in 1845, the same year as the Holy See's recognition of the parent body. Those national councils are in turn represented in the Society's General Council by their own presidents, alongside a President General elected to lead the confederation as a whole, with an International General Assembly convening every six years as the Society's highest governing body. What is now the International Confederation of the Society of Saint Vincent de Paul is that top layer: the coordinating body the national councils belong to, rather than a separate charity operating alongside them.
