Twelve Years' Truce

The Twelve Years' Truce was the name given to the cessation of hostilities between the Habsburg rulers of Spain and the Southern Netherlands and the Dutch Republic as agreed in Antwerp on 9 April 1609. It was a watershed in the Eighty Years' War, marking the point from which the independence of the United Provinces received formal recognition by outside powers. For the time of its duration, the Truce allowed King Philip III and his favorite minister the Duke of Lerma to disengage from the conflict in the Low Countries and devote their energies to the internal problems of the Spanish Monarchy. The Archdukes Albert and Isabella used the years of the Truce to consolidate Habsburg rule and to implement the Counter-Reformation in the territories under their sovereignty.

The war in the Low Countries reached a stalemate in the 1590s. After the fall of Antwerp in 1585, Spain's Philip II ordered Alexander Farnese to direct his military actions first towards the failed campaign of the Spanish Armada, then against France to prevent the succession of Henry IV, a Protestant. In the following years the Army of Flanders was entirely on the defensive. Unable to sustain the cost of a war on three fronts, Philip II was forced to declare a suspension of payments in 1596. Spain's predicament was adroitly used by Stadtholder Maurice. In a series of campaigns, the Republic's army surprised Breda in 1590, took Deventer, Hulst and Nijmegen the following year and captured Groningen in 1594. By that stage the Army of Flanders had lost almost all its strategic positions north of the great rivers.
