The Pope at the time of the Cid was Pope Victor II, a German, and made pope by Henry III, the Holy Roman emperor.
And the Pope being a German, and the friend of Henry, sent to the King to admonish him, and told him that unless he obeyed he would proclaim a crusade against him; and in like manner the Emperor, and the King of France, and the other Kings, sent to exhort him to obedience, defying him if he should refuse.
The tidings of this great enterprise spread far and wide, and adventurers came from all parts to be present, not only they of Castille and Leon, Asturias and Nagera, Galicia and Portugal, but King Sancho Ramirez of Aragon came also, with the flower of Aragon and Navarre and Catalonia, and Franks and Germans and Italians, and men of other countries, to bear their part in so great and catholic a war.
Then he told him that the land beyond sea was in such state that they weened it would be lost, and that the Christians would win it, so great a Crusade had gone forth against it from Germany, and from France, and from Lombardy, and Sicily, and Calabria, and Ireland, and England, which had won the city of Antioch, and now lay before Jerusalem.
