Philip, on the other hand, now a second time a widower, was to espouse Henry's daughter Isabella, already betrothed to the Infant Don Carlos, and to receive with her a dowry of four hundred thousand crowns.

The restitutions were to be commenced by Henry, and to be completed within three months.

Philip was to restore his conquests in the course of a month afterwards.
Most of the powers of Europe were included by both parties in this treaty: the Pope, the Emperor, all the Electors, the republics of Venice, Genoa and Switzerland, the kingdoms of England, Scotland, Poland, Denmark, Sweden; the duchies of Ferrara, Savoy and Parma, besides other inferior principalities.

Nearly all Christendom, in short, was embraced in this most amicable compact, as if Philip were determined that, henceforth and forever, Calvinists and Mahometans, Turks and Flemings, should be his only enemies.
The King of France was to select four hostages from among Philip's subjects, to accompany him to Paris as pledges for the execution of all the terms of the treaty.

The royal choice fell upon the Prince of Orange, the Duke of Alva, the Duke of Aerschot, and the Count of Egmont.
Such was the treaty of Cateau Cambresis.
