He may, to some extent, have counted upon the fact that, of Cardinal della Rovere's bastard children, only a daughter--Felice della Rovere--survived.

Raffaele, the last of his bastard boys, had died a year ago.

Thus, Cesare may have concluded that the cardinal having no sons whose fortunes he must advance, would lack temptation to break faith with him.
From all this it resulted that, at the Conclave of November 1, Giuliano della Rovere was elected Pope, and took the name of Julius II; whilst Valentinois, confident now that his future was assured, left the Castle of Sant' Angelo to take up his residence at the Vatican, in the Belvedere, with forty gentlemen constituting his suite.
On November 3 Julius II issued briefs to the Romagna, ordering obedience to Cesare, with whom he was now in daily and friendliest intercourse.
In the Romagna, meanwhile, the disturbances had not only continued, but they had taken a fresh turn.

Venice, having reseated Malatesta on the throne, now vented at last the covetousness she had ever, herself, manifested of that dominion, and sent a force to drive him out again and conquer Rimini for the Republic.
Florence, in a spasm of jealous anger at this, inquired was the Pope to become the chaplain of Venice, and dispatched Macchiavelli to bear the tale of these doings to Julius.
Under so much perpetual strife the strength of the Romagna was gradually crumbling, and Cesare, angry with Florence for never going beyond lip-service, expressed that anger to Macchiavelli, informing the ambassador that the Signory could have saved the Romagna for him with a hundred men-at-arms.
The duke sent for Giustiniani, the ambassador of Venice, who, however, excused himself and did not go.

This within a week of the new Pope's election, showing already how men discerned what was in store for Valentinois.
