Gerard Brantsen was one of the Dutch signatories to the treaty ending a war that began in what year?
Fourth Anglo-Dutch War The Fourth Anglo-Dutch War (1780–1784) was a conflict between the Kingdom of Great Britain and the Dutch Republic. The war, contemporary with the War of American Independence, broke out over British and Dutch disagreements on the legality and conduct of Dutch trade with Britain's enemies in that war.
Treaty of Vienna (1656) The treaty of Vienna, concluded on 1 December 1656, was an Austro–Polish alliance during the Second Northern War. Habsburg emperor Ferdinand III agreed to enter the war on the anti-Swedish side and support the Polish king John II Casimir with 4,000 troops. The treaty was, however, dissatisfying for John II Casimir, who had hoped for more substantial aid, and further ineffective as Ferdinand III died three days after giving his signature. A similar, but more effective alliance was concluded by Ferdinand III's successor Leopold I in the Treaty of Vienna (1657).
