Martina, and Costantine III, Heracleonas half-brother, expected to reign over the West from Rome, are enthroned according to Heraclius’ last will; but when Constantine quickly dies, Patriarch Pyrrhus and the Senate, following popular hate against Martina, depose and mutilate her and Heracleonas (plus Martina’s other surviving sons). In their place the young Belisarius III (*OTL Constans II), son of Constantine III, is enthroned under the regency of the Senate.

The Narentan Slavic horde is stopped by an unholy Byzantine-Lombard alliance in the battle of the Marmore Waterfalls (Umbria); but neither the Lombards nor the Byzantines can chase the surviving Slavs from the inner south of Italy, where the tribal Slavic duchy of Idalska is established with its capital in Avlengrad/Avellino
644-646 The Korean kingdom of Koguryo stages a brilliant defence against two subsequent Chinese invasions

The Arabs conquer the Byzantine fortress of Melitene (*OTL Malatya) on the upper Euphrates
647 The Arabs unleash their first raids into Anatolia; they also conquer Cyprus and the Fars/Persis (southern Persia). Harshavardhana of Kanauj is newly repulsed by the Chalukyas in the Malwa, then dies heirless and his empire splinters into local kingdoms. He was the last great Budddhist ruler of India: Buddhism itself begins to quickly disappear from northern India, save for the Bengal area. The Slavs of Idalska (southern Italy) take and raze Naples; the surviving Byzantine forces in the region are besieged in Salerno and the Amalfi peninsula. The loyalist Byzantine fleet clears the Aegean from Gregory’s supporters. Following the Byzantine-Lombard thaw after the Slavic aggression in Italy, the archbishop of Milan John Bonus reinstates the Ambrosian see in its due town after 73 years of exile.

650 The Salasthambhas replace the extinct Varman dynasty on the throne of Kamrupa/Assam (NE India). The Qarluq/Kipchak, a collateral Uygur group, under the pressure of the T’ang Chinese and their Uygur vassal migrate to the upper Irtyš river region
ca. 650 The Theme State structure is finally established within the Byzantine empire: each theme is a civilian and military province, inhabited by peasant-soldiers and ruled by a strategos (generalissimo). The Slavic wave of colonization in the Sklaviniai (*OTL Balkans) stops, the area having beeen almost completely Slavicized; only the Vlachs, dispersed in semi-nomadic groups in the area, Greek and Dalmatian coastal strongholds and the solid block of Illyrians in Albania resist the barbarians. The Serbians eenforce theire rule between Macedonia and Bosnia under their “ban” (leader, prince) Svevlad. In southern Italy/Idalska, the local Slavs go rampant with piracy in both the Adriatic and Tyrrhenian Sea, sacking and pillaging from Greece to Sardinia and distant Africa. The White Croats’ kingdom arises straddling the Tatra Mountains, Silesia and Bohemia. The Khazars free themselves from Western Gökturk tutelage. The Zenete (Berber) tribe of the Jarawas, paramount in the Aurés region of Numidia, converts en masse to Judaism under its chieftain Tifanes. The city and empire of Teotihuacàn in Mexico are destroyed; local ascendancy now passes over to Cholula (near Puebla). The Srivijaya kingdom enforces its power as master of the Malacca and Sunda Straits; it also conquers the kingdom of Taruma on western Java. The Arabs start spreading Islam along the eastern coast of Africa. Budddhism spreads into the Chenla kingdom (Laos and Cambodia). The Arabs vassalize the Georgian kingdom of Khakheti. An independent Turkic-Sogdian kingdom arises in the Usrushana (the region north of Samarcanda, centered around Chach/Tashkent)
