The conspiracy known as the 'Diet of La Magione' was the consequence.

In this conjuration the Cardinal Orsini, Paolo Orsini, his brother and head of the great house, together with Vitellozzo Vitelli, lord of Citta di Castello, the Baglione of Perugia, the Bentivoglio of Bologna, Antonio da Venasso from Siena, and Oliverotto da Fermo took each a part.

The result of their machinations against the common foe was that Cesare for a moment lost Urbino, and was nearly unseated in Romagna.

But the French helped him, and he stood firm.

Still it was impossible to believe that Louis XII.
would suffer him to advance unchecked in his career of conquest; and as long as he continued between the French and the Orsini his position was of necessity insecure.
