statecraft and practised diplomatic skill of the Advocate never rendered
greater services to his country than during these last years of his long
tenure of power. A difficult question as to the succession to the
Jülich-Cleves duchies arose at the very time of the signing of the
truce, which called for delicate and wary treatment.

In March, 1609, the Duke of Jülich and Cleves died without leaving a
male heir, and the succession to these important border territories on
the Lower Rhine became speedily a burning question. The two principal
claimants through the female line were the Elector of Brandenburg and
William, Count-Palatine of Neuburg. The Emperor Rudolph II, however,
under the pretext of appointing imperial commissioners to adjudicate
upon the rival claims, aroused the suspicions of Brandenburg and
Neuburg; and these two came to an agreement to enter into joint
possession of the duchies, and were styled "the possessors." The
Protestant Union at Heidelberg recognised "the possessors," for it was
all-important for the balance of power in Germany that these lands
should not pass into the hands of a Catholic ruler of the House of
Austria. For the same reason Brandenburg and Neuburg were recognised by
the States-General, who did not wish to see a partisan of Spain
established on their borders. The emperor on his part not only refused
to acknowledge "the possessors," but he also sent his cousin Archduke
Leopold, Bishop of Passau, to intervene by armed force. Leopold seized
the fortress of Jülich and proceeded to establish himself.

It was an awkward situation, for neither the United Provinces nor the
archdukes nor the King of Spain had the smallest desire to make the
Jülich succession the cause of a renewal of hostilities, immediately
after the conclusion of the truce. The eagerness of the French king to
