Justinian II (668-711), later known as Justinian the Slit-Nosed, was the eldest son of Emperor Constantine IV, and became joint emperor in 681. He later succeeded his father as sole emperor in 685, aged sixteen. Justinian was ambitious and passionate, wishing to restore the emperor to former glories and past successes. However, Justinian's lack of finesse and his poor attitude towards any opposition to his will led to resistance throughout his reign. He was eventually deposed in a popular uprising led by Leontios in 695, who proclaimed himself emperor and exiled Justinian after having his nose cut off. Justinian soon began plotting his return from exile in Crimea, gathering supporters to him. Justinian eventually regained the throne in 705 from usurper emperor Tiberios, having both Tiberios and the imprisoned Leontios dragged out in public and executing them. His second reign was even more contentious, marked by his turning on those who had helped him reclaim the throne. Another uprising eventually occurred, led by the exiled General Bardanes. Justinian, who had been on his way to Armenia, attempted to once more rouse support for his claim, but he was arrested and executed in 711 instead, ending the Heraclian dynasty.
