The Borgias succeed in unifying the Papal States (I mean eliminate the small dukes which ruled different cities) by 1504. Pope Alexander VI does not die till 1508. French troops travelling through Rome and with the aid of mercenaries bought by the Papal States prolong the war in Naples against Spain. The Papal States switches alliances opportunistically and succeeds in taking over Tuscany and Pisa. After the war in Naples ends the French and Spanish are exhausted. The Borgia controlled Papal States, takes over Florence and Lucca as well. After Pope Alexander VI dies, he is succeeded by Pope Julius, who is Cesare Borgia. In 1515, the Spanish offer an alliance to the Papal States. Spain would assault France from its homeland with a large force. The Papal States, aided by Spain and mercenaries would attack across its northern front. Modena, Ferrara, Mantua, Savoy, Genoa, Milan were aligned with the French. Papal Sates required vast aid to raise an army for this purpose. The war was postponed for two years. In March 1517, 50000 Spanish troops began an offensive against France. At the same time 15000 Neapolitan and 20000 Papal troops attacked across the Northern Frontier of Italy. Since, the war at home was more important, France pulled out its troops from Italy. Milan had little defense. In July 1517, Milan falls. Mantua, Ferrara, Modena, Genoa all leave the war till May 1518. In the other front, Spain and France have suffered horrendous losses. They request Borgia attack on France from the other direction. The Papal States ask for the retreat of Neapolitan troops and a payment of 200000 ducats. Spain refuses. The Papal States switches sides in April . The condition of switching sides was that France would make it clear to the rulers of Savoy, Saluzzo, Montferrat that they would have to become satellite states to the Papal States. This succeeds and by September, all of North Italy except Venice is under Papal States. The front against Naples shows initial success but the attack is halted near Benevento. Naples City does not fall. The war between France and Spain goes on till 1521. By the agreement a northern part of Naples goes to the Papal States and so does all of Northern Italy occupied by Roman troops. At this time, France send delegation to Ottomans for the conclusion of alliance (OTL). The Papal States does the same. The State of the Church, offers Dalmaria and the Mediterranean territories of Venice to Ottomans if a Papal-Ottoman Alliance decimates Venice. Rome would get Venice and its Italian territories. France also signs an separate alliance with Ottomans with the aim of invasion of Southern Italy. In 1522 the invasion of Sicily under the Aragon begins. A few months after that the Papal States and the Turks also launch war on Venice. The Holy Roman Empire and Hungary also launches a front against Ottomans in the Balkans. In 1524, Venice surrender but the fighting in Sicily goes on as Spain and Naples send large number of troops. In 1525, the Papal State offer an alliance to France. French troops can travel through mainland Italy to attack Naples. France agrees. France invades Naples in December 1525. The war between Holy Roman Empire and the Ottomans is not going good for the Turks. They pull out their forces from Sicily. In March 1526, Naples City falls after a siege. Naples capitulates. A large number of troops from Sicily had to be transferred to the Naples Front by France. By May 1525, Spain has won in Sicily. A new front opens in South Naples. The war between the Holy Roman Empire, Hungary and the Ottomans has led to the occupation of South Hungary because it was outflanked from the ex-Venetian territory.
