Constans II ((ギリシア語:Κώνστας Β', ''Kōnstas II'' Latin: ''Heraclius Constantinus'' or ''Flavius Constantinus Augustus'')); 7 November 630 – 15 September 668), also called Constantine the Bearded (''Kōnstantinos Pogonatos''), was Byzantine Emperor from 641 to 668. He was the last emperor to serve as consul, in 642.〔(JSTOR: The Last Consul: Basilius and His Diptych )〕〔(JSTOR: The Iranian Factor in Byzantium during the Reign of Heraclius )〕 Constans is a diminutive nickname given to the Emperor, who had been baptized Herakleios and reigned officially as Constantine. The nickname established itself in Byzantine texts and has become standard in modern historiography. ==Biography== Constans was the son of Constantine III and Gregoria. Due to the rumours that Heraklonas and Martina had poisoned Constantine III, he was named co-emperor in 641. Later that same year his uncle was deposed, and Constans II was left as sole emperor. Constans owed his rise to the throne to a popular reaction against his uncle and to the protection of the soldiers led by the general Valentinus. Although the precocious emperor addressed the senate with a speech blaming Heraklonas and Martina for eliminating his father, he reigned under a regency of senators led by Patriarch Paul II of Constantinople. In 644 Valentinus attempted to seize power for himself but failed. Under Constans, the Byzantines completely withdrew from Egypt in 642, and Caliph Uthman launched numerous attacks on the islands of the Mediterranean Sea and Aegean Sea. A Byzantine fleet under the admiral Manuel occupied Alexandria again in 645, but after a Muslim victory the following year this had to be abandoned. The situation was complicated by the violent opposition to Monothelitism by the clergy in the west and the related rebellion of the Exarch of Carthage, Gregory the Patrician. The latter fell in battle against the army of Caliph Uthman, and the region remained a vassal state under the Caliphate until civil war broke out and imperial rule was again restored. Constans attempted to steer a middle line in the church dispute between Orthodoxy and Monothelitism by refusing to persecute either and prohibiting further discussion of the natures of Jesus Christ by decree in 648. Naturally, this live-and-let-live compromise satisfied few passionate participants in the dispute. Meanwhile, the advance of the Caliphate continued unabated. In 647 they had entered Armenia and Cappadocia and sacked Caesarea Mazaca. In the same year, they raided Africa and killed Gregory. In 648 the Arabs raided into Phrygia, and in 649 they launched their first maritime expedition against Crete. A major Arab offensive into Cilicia and Isauria in 650–651 forced the Emperor to enter into negotiations with Caliph Uthman's governor of Syria, Muawiyah. The truce that followed allowed a short respite and made it possible for Constans to hold on to the western portions of Armenia. In 654, however, Muawiyah renewed his raids by sea, plundering Rhodes. Constans led a fleet to attack the Muslims at Phoinike (off Lycia) in 655 at the Battle of the Masts, but he was defeated: 500 Byzantine ships were destroyed in the battle, and the Emperor himself was almost killed. Before the battle, chronicler Theophanes the Confessor says, the Emperor dreamed of being at Thessalonika; this dream predicted his defeat against the Arabs because the word Thessalonika is similar to the sentence "thes allo niken", which means "gave victory to another (the enemy)".〔«θὲς ἄλλῳ νὶκην», see Bury, John Bagnell (1889), ''(A history of the later Roman empire from Arcadius to Irene )'', Adamant Media Corporation, 2005, p.290. ISBN 1-4021-8368-2〕 Caliph Uthman was preparing to attack Constantinople, but he did not carry out the plan when the first Fitna broke out in 656. In 658, with the eastern frontier under less pressure, Constans defeated the Slavs in the Balkans, temporarily reasserting some notion of Byzantine rule over them and resettled some of them in Anatolia (ca. 649 or 667). In 659 he campaigned far to the east, taking advantage of a rebellion against the Caliphate in Media. The same year he concluded peace with the Arabs. Now Constans could turn to church matters once again. Pope Martin I had condemned both Monothelitism and Constans' attempt to halt debates over it (the Type of Constans) in the Lateran Council of 649. Now the Emperor ordered his Exarch of Ravenna to arrest the Pope. Exarch Olympius excused himself from this task, but his successor, Theodore I Calliopas, carried it out in 653. Pope Martin was brought to Constantinople and condemned as a criminal, ultimately being exiled to Cherson, where he died in 655. Constans grew increasingly fearful that his younger brother, Theodosius, could oust him from the throne; he therefore obliged Theodosius to take holy orders and later had him killed in 660. Constans' sons Constantine, Heraclius, and Tiberius had been associated on the throne since the 650s. However, having attracted the hatred of citizens of Constantinople, Constans decided to leave the capital and to move to Syracuse in Sicily. From there, in 663, he launched an assault against the Lombard Duchy of Benevento, which then encompassed most of Southern Italy. Taking advantage of the fact that Lombard king Grimoald I of Benevento was engaged against Frankish forces from Neustria, Constans disembarked at Taranto and besieged Lucera and Benevento. However, the latter resisted and Constans withdrew to Naples. During the journey from Benevento to Naples, Constans II was defeated by Mitolas, Count of Capua, near Pugna. Constans ordered Saburrus, the commander of his army, to attack again the Lombards, but he was defeated by the Beneventani at Forino, between Avellino and Salerno. In 663 Constans visited Rome for twelve days—the only emperor to set foot in Rome for two centuries—and was received with great honor by Pope Vitalian (657–672). Although on friendly terms with Vitalian, he stripped buildings, including the Pantheon, of their ornaments and bronze to be carried back to Constantinople, and in 666 declared the Pope of Rome to have no jurisdiction over the Archbishop of Ravenna, since that city was the seat of the exarch, his immediate representative. His subsequent moves in Calabria and Sardinia were marked by further strippings and request of tributes that enraged his Italian subjects. According to Warren Treadgold, the first ''themes'' were created between 659 and 661, during the reign of Constans II.〔Warren Treadgold, Byzantium and Its Army 284-1081 (Stanford: Stanford University Press, 1995). pp. 23-25;72-3.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Constans II」の詳細全文を読む スポンサード リンク
