Decade of 1260s
1260: The Roman armies conquer the Byzantium's vassal territory of Lazica, establishing the border with the Turks along the western Caucasus, thus improving the safety of the northeastern border.
1261: The duchy of New England is expanded to the south, up to the bay of the Barbars (OTL Delaware Bay), after defeating some of the local tribes in the battle of Little Birmingham. Many settlers from Ireland and northern Britain are established in these new lands.
1262: Massive landings of Roman troops in the Aegean coast of Anatolia. The pro-Union noblemen convinces the authorities of the cities of Smyrna and New Ephesus to surrender the cities to the Romans without being damaged.
1263: Battle of Adrianople: the defeat of the last Byzantinist troops in the Balkans opens the doors of Constantinople to the Roman forces. The city is partially sacked and part of its walls dismantled. However, Charles VII calls for respecting the properties of the pro-Union party in the city.
1264: Peace between Persia and Turkey: the Turks recover some of their lost territories in the northeastern Iranian plateau, while the Persians ensure their control over the Baluchistan.
1265: The Emperor of Rome Charles VII and the Empress Zoe enter Constantinople. Basileus Michael, fearing the advance of the Romans into Bythinia, flees to the port of Sinope and takes a ship with unknown destination: after the flight of Michael, the Byzantinists lose heart and they are defeated across all the fronts in Anatolia.
1266: The Malians discover the Amazon river; many Muslim North African settlers which originally fled from the Andalusian states to the Mali Empire now migrate again to New Mali in order to establish there their own communities, as many of them suffered of discrimination in Mali.
1267: The last stronghold of the Byzantinists in Iconium is captured by the Romans: the civil war in the East is over and the old Roman Empire is reunified. The last Byzantine themas are reorganized in typical Roman duchies, thus unifying all the administration across the Empire.
1268: Charles VII and Zoe abdicate and their son, 25 years-old Charles Theodore I, is crowned first Emperor of the reunified Roman Empire. He is crowned only in Jerusalem, in order to do not favour Milan or Constantinople, and this tradition will be followed with the future Emperors.
1269: First Diet in Pavia with all the duchies of the reunified Empire. The parties of the Diet also suffer reorganization: the Greek duchies align with the Italian party, while the Anatolian ones form their own new party along with the Levant and Northern African duchies, in order to balance the Italian-Germanic power in the Diet.
