taking any active part in affairs of state, he had
turned his energies into the pursuit of pleasure, and had been leading a
gay and dissolute life. His accession to power was, however, speedily to
prove that he was possessed of great abilities, a masterful will and a
keen and eager ambition. He had strongly disapproved of the trend of the
peace negotiations at Muenster, and would have preferred with the help of
the French to have attempted to drive the Spaniards out of the southern
Netherlands. The preliminaries were, however, already settled in the
spring of 1647; and the determination of the province of Holland and
especially of the town of Amsterdam to conclude an advantageous peace
with Spain and to throw over France rendered the opposition of the young
Stadholder unavailing. But William, though he had perforce to acquiesce
in the treaty of Muenster, was nevertheless resolved at the earliest
opportunity to undo it. Thus from the outset he found himself in a
pronounced antagonism with the province of Holland, which could only

Maurice was confronted in the years that followed the truce of 1609,
and, to a less degree, his father after 1640.

in Holland itself, among that great majority of the inhabitants, both of
town and country, who were excluded from all share in government and
administration and were generally Orangist in sympathy. He had also with
him the officers of the army and navy and the preachers. His chief
advisers were his cousin William Frederick, Stadholder of Friesland, and
Cornelis van Aerssens (son of Francis) lord of Sommelsdijk. By the
agency of Sommelsdijk he put himself in secret communication with Count
d'Estrades, formerly French ambassador at the Hague, now Governor of
Dunkirk, and through him with Mazarin, with the view of concluding an
alliance with France for the conquest o
