Feo's death had not diminished the power…
March 1499 CE
Feo's death had not diminished the power of Ottaviano's mother, who continued to take decisions on his behalf.
Ottaviano has been employed twice by the Florentines as a condottiero to defend Florentine interests.
He had been offered fifteen thousand florins in 1497 and ten thousand in 1499.
Niccolò Machiavelli undertakes negotiations on the second occasion.
Ottaviano is still only the nominal leader, as the actual negotiations are conducted with Caterina.
However, Ottaviano personally commands small forces in these local wars.
In 1498 he had taken part in the siege of Pisa with one hundred men-at-arms and one hundred light horse.
In 1499 he aids Ludovico Sforza, who is at war with the French and Venetians.
At this point the Borgias decide to intervene.
In the meantime, Louis XII, after succeeded to the French throne., has claimed the rights both to the Duchy of Milan as a grandson of Valentina Visconti, and to the Kingdom of Naples as heir to the House of Anjou.
Before starting his campaign in Italy, Louis XII had secured an alliance with Savoy, the Republic of Venice and Pope Alexander VI, who has allied himself with Louis XII in return for the King's support in establishing Alexander's son Cesare Borgia, the Duke of Valentinois, as ruler in Romagna.
Alexander issues a Papal Bull on March 9, 1499 to invalidate the investiture of the feudal lords, including Caterina.
