Tiberios 1 was the son of the emperor Constans II (Konstans 1) and brother of Konstantinos 2 and Heraklios 1; Theoph. AM 6153 (καὶ τοὺς τρεῖς υἱοὺς αὐτοῦ, Κωνσταντῖνον, Ἡράκλειον καὶ Τιβέριον), Theoph. AM 6160 (τοῦ ἰδίου πατρός ... βασιλεύει τῶν Ῥωμαίων μετὰ Τιβερίου καὶ Ἡρακλείου, τῶν ἰδίων ἀδελφῶν), Theoph. AM 6161 (Κωνσταντῖνος σὺν τοῖς ἀδελφοῖς αὐτοῦ. ... ὁ δὲ βασιλεὺς τοὺς ἀδελφοὺς αὐτοῦ ἐρρινοκόπησεν), Theoph. AM 6173 (ἀπώσατο Κωνσταντῖνος τοὺς ἀδελφοὺς αὐτοῦ τῆς βασιλείας, Ἡράκλειον καὶ Τιβέριον), Zon. XIV 19. 31 (διὸ καὶ τὴν βασίλισσαν καὶ τοὺς υἱοὺς αὐτοῦ - τρεῖς δ' ἦσαν, Κωνσταντῖνος, Ἡράκλειος καὶ Τιβέριος). Cf. also Phausta 1.
In 661/662, when their father planned to transfer the seat of government back to the West, Tiberios 1 and his brothers were not allowed by the inhabitants to leave Constantinople and join him in the West: Theoph. AM 6153, cf. AM 6160, Zon. XIV 19. 31-33. The three brothers are said to have ruled together after their father's death: Theoph. AM 6160, AM 6161. At the start of their brother Constantine IV (Konstantinos 2)'s reign Heraklios 1 and Tiberios 1 were not crowned and had no title (οὐδεμίαν ἀξίαν εἶχον - but see further on this Mango and Scott, Theophanes, p. 492, n. 1); after troops from the east had asked that all three be crowned, Constantine IV (Konstantinos 2) executed the leaders of the troops amd had the noses of his brothers cut off: Theoph. AM 6161 (see however Mango and Scott, Theophanes, p. 492, n. 2 observe that this episode is misplaced), Zon. XIV 20. 5-8. Tiberios 1 and Heraklios 1 were driven from the throne by Constantine IV (Konstantinos 2) in 681/682: Theoph. AM 6173 (in year thirteen of Constantine). According to the Liber Pontificalis, in 678 he and his two brothers were all Augusti: Lib. Pont. 81. 3 ("
Son of the emperor Konstans 1 and brother of Konstantios (Konstantinos 2) and Heraklios 1; he and his brothers were made autokrators at Constantinople by their father after Konstans 1 had gone to Sicily: Bar Hebr., p. 99, Mich. Syr. II 451. In the year 981 Sel. (669/670) he and Heraklios 1 were appointed co-emperors by Konstantinos 2 and their images were put on the coinage: Bar Hebr., p. 101, Mich. Syr. II 454. After the birth of Ioustinianos 1, the son of Konstantinos 2, they were dismissed; they were brought before the senate and when they refused to abandon their imperial position were exiled: Bar Hebr., pp. 101-102, Mich. Syr. II 455-456. He and Heraklios 1 refused to accept the heresy of Maximos 10 which had been rejected by their father, Konstans 1: Mich. Syr. II 452.
