From hence he was recalled by a more formidable enemy nearer home: for Robert Earl of Northumberland, overrating his late services against the Scots, as much perhaps and as unjustly as they were undervalued by the King, refused to come to his court, which, in those days, was looked on as the first usual mark of discontent in a nobleman; and was often charged by princes as a formal accusation.

The earl having disobeyed the King's summons, and concerted matters with other accomplices, broke out into open rebellion, with intentions to depose King William, and set up Stephen Earl of Albemarle, son of a sister to William the Conqueror: but all was prevented by the celerity of this active prince; who, knowing that insurrections are best quelled in their beginnings, marched with incredible speed, and surprised the rebels at Newcastle, took the castles of Tynemouth and Bamburgh; where the obstinacy of the defendants provoked him, contrary to his nature, to commit cruelties upon their persons, by cutting off their hands and ears, and other the like inhumanities.

The earl himself was taken prisoner as he endeavoured to make his escape; but suffered no other punishment than to be confined for the rest of his life.[11] [Footnote 11: Which was thirty years.

[D.S.]] About this time began the Holy War for recovering of Palestine; which having not been the enterprise of any one prince or state, but that wherein most in Christendom had a share, it cannot with justice be silently passed over in the history of any nation.
Pope Urban the Second, in a council at Clermont, made a pathetic exhortation, shewing with what danger and indignity to Christendom the Turks and Saracens had, for some ages, not only overrun all Asia and Africa, where Christianity had long flourished; but had also made encroachments into Europe, where they had entirely subdued Spain, and some other parts; that Jerusalem, the holy city, where our Saviour did so many miracles, and where His sepulchre still remained, to the scandal of the Christian name, lay groaning under the tyranny of infidels; that the swords which Christian princes had drawn against each other, ought to be turned against the common enemy of their name and religion; that this should be reckoned an ample satisfaction for all their past sins; that those who died in this expedition should immediately go to Heaven, and the survivors would be blessed with the sight of our Lord's sepulchre.
Moved by these arguments, and the influence of the person who delivered them, several nobles and prelates immediately took upon them the cross; and the council dissolving in this high fit of zeal, the clergy, upon their return home, prevailed so far in their several countries, that in most parts of Europe some great prince or lord became a votary for the Holy Land; as Hugh the Great, brother to the King of France; Godfrey Duke of Lorraine; Reimond Count of Toulouse; Robert Duke of Normandy, and many others.

Neither ought it to be forgotten, that most of these noble and generous princes, wanting money to maintain the forces they had raised, pawned their dominions to those very prelates who had first engaged them in this enterprise: doubtless a notable mark of the force of oratory in the churchmen of those ages, who were able to inspire that devotion into others, whereof they seemed so little sensible themselves.
But a great share in the honour of promoting this religious war, is attributed to the zeal and industry of a certain French priest, commonly called Peter the Hermit; who being at Jerusalem upon pilgrimage some time before, and entering often into private treaty with the patriarch of that city, came back fully instructed in all the measures necessary for such a war: to these was joined the artifice of certain dreams and visions that might pass for divine admonition: all which, added to the piety of his exhortations, gave him such credit with the Pope, and several princes of Christendom, that he became in his own person the leader of a great army against the infidels, and was very instrumental for engaging many others in the same design.
What a spirit was thus raised in Christendom among all sorts of men, cannot better be conceived than from the vast numbers of these warlike pilgrims; who, at the siege of Nice, are said to have consisted of 600,000 foot, and 100,000 horse: and the success at first was answerable to the greatness of their numbers, the valour of their leaders, and the universal opinion of such a cause; for, besides several famous victories in the field, not to mention the towns of less importance, they took Nice, Antioch, and at last Jerusalem, where Duke Godfrey was chosen king without competition.
