Dengizich
Dengizich (died in 469), was a Hunnic ruler and son of Attila. After Attila's death in 453 AD, his Empire crumbled and its remains were ruled by his three sons, Ellac, Dengizich and Ernak. He succeeded his older brother Ellac in 454 AD, and probably ruled simultaneously over the Huns in dual kingship with his brother Ernak, but separate divisions in separate lands.

Etymology
The name recorded as Δεγγιζίχ (De(n)gizikh) by Priscus has abbreviated variant Διν[γι]ζι (Din(gi)zi) in Chronicon Paschale, Den(git)zic by Marcellinus Comes, and Din(gi)tzic by Jordanes. Din(t)zic and Denzic render a Germanic pronunciation *Denitsik, with the frequent dropping of "g". Otto Maenchen-Helfen considered it a derivation from Turkic *Däŋiziq, meaning "little lake". Omeljan Pritsak considered the reconstructed form deŋir + čig > deŋičig, with the meaning "ocean-like".

History
The oldest brother Ellac died in 454 AD, at the Battle of Nedao. Jordanes recorded "When Ellac was slain, his remaining brothers were put to fight near the shore of the Sea of Pontus where we have said the Goths settled ... dwelling again in their ancient abodes". Jordanes recounts events in c. 454-455:

"[After the Ostrogoths led by their king Valamir, and his brothers Theodemir and Vidimir received Pannonia] Now it happened that the sons of Attila, regarding the Goths as deserters from their rule, came against them as though they were seeking fugitive slaves and attacked Valamir alone, when his brothers knew nothing of it. He sustained their attack, though he had but few with him, and after harassing them a long time, so utterly overwhelmed them that scarcely a portion of the enemy remained. The remnant turned in flight and sought the parts of Scythia which border on the stream of the river Danaber, which the Huns call in their own tongue Var. Whereupon he sent a messenger of good tidings to his brother Theodemir ... on the very day the messenger arrived ... Theoderic was born [in 454]". 

Priscus recorded that in 465-466, Dengizich and his brother Ernak sent diplomats to Constantinople. They wanted a peace treaty, and a market place on Danube "according to the ancient customs" between Romans and Huns, but were rejected. Then Dengizich on his own moved to the bank of the Istros (lower Danube) and threatened to break into Thrace unless he was granted lands and subsidies. He rejected negotiations with Anagast (who defended the Danube in Thrace), and sent diplomats directly to the emperor Leo I. However, Leo I replied that "he was ready to do everything if they came to him and offered him obedience. He took pleasure, he said, in nations which came seeking alliances".

In 467, Dengizich crossed the frozen Danube, and although expected the Huns in the South to join him, large groups of undefined Goths and Scythians moved on their own. Probably after the turning Battle of Nedao, some groups of Goths still remained under Hun authority. Basiliscus, Goths Anagast and Ostryis, and Hun Chelchal were generals who led Roman armies. They managed to besiege the Goths into a valley, and the Scythians "oppresed by hunger and lack of necessities sent an embassy to the Romans that if they were to surrender and be allotted lands, they would obey the Romans in whatever they wanted". The report continues: 

Anagast sent a large group of bucellari against the barbarians, but the war dragged on for two years.

Jordanes recounts events in c. 468:

"Now after firm peace was established between Goths and Romans, the Goths found that what they received from the emperor was not sufficient for them. Furthermore, they were eager to display their wonted valor, and so began to plunder the neighboring peoples around them, first attacking the Sadagis, who held the interior of Pannonia. When Dintzic, king of the Huns, a son of Attila, learned this, he gathered to him the few who still seemed to have remained under his sway, namely, the Ultzinzures, the Angisciri, the Bittugures and the Bardores. Coming to Bassianae (see Battle of Bassianae), a city of Pannonia, he beleaguered it and began to plunder its territory. When the Goths learned this, they abandoned the expedition they had planned against the Sadagis and turned upon the Huns and drove them so ingloriously from their own land that those who remained have been in dread of the arms of the Goths from that time down to the present day."

The war ended in 469. Marcellinus Comes shortly recorded "The head of Dinzic, son of Attila, king of the Huns, was brought to Constantinople". The Chronicon Paschale recounts "Dinzirichus, Attila's son, was killed by Anagastes, general in Thrace. His head was brought to Constantinople, carried in procession through the Middle Street, and fixed on a pole at the Wooden Circus. The whole city turned out to look at it".
