The Peace of Ostia was made in 1565, ending the second Occidental-Seljuk War.
The Rum-Seljuks had to give up:
- Latium (to Florence)
- The Marches,
- Tunis and
- Sicily (to the Triple Monarchy of England-Castille-Portugal).
The Romans displaced ~20 years ago returned in triumph. The victorious Italians demanded that the Pope returned to Rome, which the French king denied however.
