The CDU donations scandal was a political scandal resulting from the illegal forms of party financing used by the German Christian Democratic Union (CDU) during the 1990s. These included accepting hidden donations, the non-disclosure of cash donations, the maintenance of secret bank accounts, and illegal wire transfers to and from foreign banks. As a consequence, two of the leading CDU figures of the 1980s and 1990s, Helmut Kohl and Wolfgang Schäuble, lost their political influence, with Angela Merkel and Roland Koch emerging as the most powerful German conservative politicians.
