During the Eighty Years' War with Spain, France supported the Dutch Republic as part of a general policy of opposing Habsburg power. Johan de Witt, Dutch Grand Pensionary from 1653 to 1672, viewed them as crucial for Dutch security and against his domestic Orangist opponents. Louis provided support in the 1665-1667 Second Anglo-Dutch War but used the opportunity to launch the War of Devolution in 1667. This captured Franche-Comté and much of the Spanish Netherlands; French expansion in this area was a direct threat to Dutch economic interests.
