Erfurt Union
He introduced the Sisters of Charity into Baden; transformed his own house into an ecclesiastical college; during the famine of the winter of 1846, he fed thousands of starving people in the Black Forest; and he organized the Catholics politically and formed them into societies. In 1848 Buss presided over the first general assembly of the German Catholic associations (Katholikentag) in Mainz. He represented Ahaus-Steinfurt in the German Parliament at Frankfurt. There, as in the Erfurt Union Parliament, where he was the leader of the Greater-Germany Party, he favoured Austria as against Prussia. When opposition to the Catholic Church in Baden developed into open hostility, Buss was at the side of the archbishop, Hermann von Vicari.
