The Rhenish Missionary Society (Rhenish – of the river Rhine) was one of the largest Protestant in Germany. Formed from smaller missions founded as far back as 1799, the Society was amalgamated on 23 September 1828, and its first missionaries were ordained and sent off to South Africa by the end of the year. The London Missionary Society was already active in the area, and a closer working relationship was formed with them. The Society established its first mission station in the Cederberg in 1829, named Wupperthal, and predated the naming of the German city by 100 years.
