Maximilian von und zu Trauttmansdorff

Maximilian von und zu Trauttmansdorff (1584–1650) was an Austrian statesman born in Graz. After studying law, he joined the Aulic Council in 1609 and became a key diplomat for Ferdinand II from 1618, arranging the emperor's alliance with Bavaria in 1619 and concluding the Peace of Nikolsburg with Gabriel Bethlen in 1621.

From 1633 he was Obersthofmeister and closest adviser to Ferdinand III, negotiating the Peace of Prague in 1635. As head of the imperial delegation at Westphalia, he was a chief architect of the Peace of Westphalia, and in 1648 persuaded Ferdinand to accept peace without Spain's involvement or military support.
