Anthonie Heinsius

Anthonie Heinsius (1641–1720) was a Dutch statesman born at Delft. He became pensionary of Delft in 1679. Sent to Paris in 1682 to protest Louis XIV's seizure of Orange, he was threatened with the Bastille and returned an opponent of France. In 1689 he became Grand Pensionary of Holland and drove the anti-French coalition in the Nine Years' War.

After William III died in 1702, Heinsius became the Republic's main foreign policymaker. During the War of the Spanish Succession he helped direct alliance strategy with Marlborough and Prince Eugene, and died in office in 1720.
