582 THE HISTORY OF MEDIEVAL EUROPE of Ten gradually became perhaps the most potent single factor. In that year a dangerous conspiracy led to the es- tablishment of this new board, which was at first intended as a temporary committee of public safety, but was after- ward retained as a permanent feature of the constitution.
