6th-century murdered monarchs

Amalasuintha (495 – 30 April 535) was a ruler of the Ostrogothic Kingdom from 526 to 535. Initially serving as regent for her son Athalaric, she became queen regnant after his premature death. Highly educated, Amalasuintha was praised by both Cassiodorus and Procopius for her wisdom and her ability to speak three languages (Greek, Gothic, and Latin). Her status as an independent female monarch, and obvious affinity for Roman culture, caused discontent among the Gothic nobles in her court, and she was deposed and killed after six months of sole rule. Eastern Roman Emperor Justinian I used her d

king of Neustria from 561 to 584 (537-584)

Frankish king

Alboin (530s – 28 June 572) was king of the Lombards from about 560 until 572. During his reign the Lombards ended their migrations by settling in Italy, the northern part of which Alboin conquered between 569 and 572. He had a lasting effect on Italy and the Pannonian Basin; in the former, his invasion marked the beginning of centuries of Lombard rule, and in the latter, his defeat of the Gepids and his departure from Pannonia ended the dominance there of the Germanic peoples.

The 23th Sassanid Emperor (579–590)

Gesalic (; ; ; ; – 513), was a king of the Visigoths from 507 to 511, and died in 513.

Amalaric (; Spanish and Portuguese: Amalarico; 502–531) was king of the Visigoths from 522 until his assassination. He was a son of king Alaric II and his first wife Theodegotha, daughter of Theodoric the Great.

Theodahad, also known as Thiudahad (; 480 – December 536), initially ruled the Ostrogothic Kingdom jointly with his cousin Amalasuintha. She elevated him to co-monarch in late 534, following the death of her son, King Athalaric, likely seeking male support to legitimize her regency. However, seeking sole power, Theodahad betrayed Amalasuintha; he had her imprisoned and subsequently murdered around April 30, 535. His tenure as sole ruler proved short and tumultuous, ending with his deposition and death in December 536 while fleeing the forces of his successor, Witiges.

Theudis (Gothic: 𐌸𐌹𐌿𐌳𐌴𐌹𐍃, Þiudeis, Spanish: Teudis, Portuguese: Têudis), ( 480 – June 548) was king of the Visigoths in Hispania from 531 to 548.

Hilderic (Latin: Flavius Hildericus) (460s – 533) was the penultimate king of the Vandals and Alans in North Africa in Late Antiquity (523–530).

Some Visigothic king lists skip Theudigisel, as well as Agila I, going directly from Theudis to Athanagild.

Vistahm or Bistam (also transliterated Wistaxm, wsthm), was a Parthian dynast of the Ispahbudhan house, and maternal uncle of the Sasanian king of kings of Iran, Khosrow II (). Vistahm helped Khosrow regain his throne after the rebellion of another Parthian noble Bahram Chobin, of House of Mihran, but later led a revolt himself, and ruled independently over a region which encompassed the entire Iranian East until he was defeated by Khosrow and his allies.
