The Convention of Turin was a 1742 agreement between Austria and Sardinia signed in the Sardinian capital of Turin. It created a military alliance between the states, directly principally against Spain. It was signed by the Sardinian Chief Minister the Marquis D'Ormea and the Austrian envoy Count Schulenburg.
