Some of the most important voluntary social service agencies and church-related groups predate the unification of Germany in 1871; others date from the last decades of the nineteenth century. The first German chapter of the International Red Cross was founded in 1863. Out of it grew the German Red Cross, one of the country's key voluntary agencies. The Innere Mission, which later became the Diakonisches Werk of the Evangelical Church in Germany, was founded in 1848. The Roman Catholic charity Deutscher Caritasverband, the largest of the voluntary welfare associations, dates from 1897. The German Non-Denominational Welfare Association, as it became known after 1932, was founded in 1920 to represent all nonchurch-related hospitals. The Workers' Welfare Organization was founded in 1919 from numerous Social Democratic women's groups working for the well-being of children.
