Sassanid Persia in the context of "Perpetual Peace (532)"

Chaturanga (Sanskrit: चतुरङ्ग, IAST: caturaṅga, pronounced [tɕɐtuˈɾɐŋɡɐ]) is an ancient Indian strategy board game. It is first known from India around the seventh century AD.

While there is some uncertainty, the prevailing view among chess historians is that chaturanga is the common ancestor of the board games chess, xiangqi (Chinese), janggi (Korean), shogi (Japanese), sittuyin (Burmese), makruk (Thai), ouk chatrang (Cambodian) and modern Indian chess. It was adopted as chatrang (shatranj) in Sassanid Persia, which in turn was the form of chess brought to late-medieval Europe.

Utik (Armenian: Ուտիք, romanized: Utik’), also known as Uti, was a historical province and principality within the Kingdom of Armenia. It was ceded to Caucasian Albania following the partition of Armenia between Sassanid Persia and the Eastern Roman Empire in 387 AD. Most of the region is located within present-day Azerbaijan immediately west of the Kura River, while a part of it lies within the Tavush province of present-day northeastern Armenia.

The Nestorian schism (a.d. 431–544) was a split between the Christian churches of Sassanid Persia, which affiliated with Nestorius, and those that later became the Catholic and Orthodox churches. The schism rose out of a Christological dispute, notably involving Cyril (Patriarch of Alexandria) and Nestorius (Patriarch of Constantinople).

The First Council of Ephesus in 431 and the Council of Chalcedon in 451 condemned Nestorius and his doctrine, which emphasized the radical distinctness between Christ's human and divine natures. That forced a breach between the churches that defended Nestorius and the state church of the Roman Empire, which caused the Church of the East, the Christian church of Sassanid Persia, to become known as the Nestorian Church, as it took the side of Nestorius.

The Vandalic War (533–534) was a conflict fought in North Africa between the forces of the Byzantine Empire (also known as the Eastern Roman Empire) and the Germanic Vandal Kingdom. It was the first war of Emperor Justinian I's Renovatio imperii Romanorum, wherein the Byzantines attempted to reassert Roman sovereignty over territory formerly controlled by the Western Roman Empire.

The Vandals occupied Roman North Africa in the early 5th century and established an independent kingdom there. Under their king, Geiseric, the Vandal navy carried out pirate attacks across the Mediterranean, sacked Rome in 455, and defeated a Roman invasion in 468. After Geiseric's death in 477, relations with the Eastern Roman Empire were normalized, although tensions flared up occasionally due to the Vandals' adherence to Arianism and their persecution of the Nicene native population. In 530, a palace coup occurred in Carthage due to a defeat against the Moorish war chief of the Frexes tribe Antalas, for which Gelimer blamed Hilderic, and the Vandals overthrew the pro-Roman Hilderic and replaced him with his cousin Gelimer. The Eastern Roman emperor Justinian took this as a pretext to intervene in Vandal affairs, and after securing the eastern frontier with Sassanid Persia in 532, he began preparing an expedition under general Belisarius, whose secretary Procopius wrote the main historical narrative of the war. Justinian took advantage of rebellions in the remote Vandal provinces of Sardinia and Tripolitania. These not only distracted Gelimer from Justinian's preparations but significantly weakened Vandal defenses through the dispatch of the bulk of the Vandal navy and army under Gelimer's brother Tzazo to Sardinia.

Heraclius the Elder (Greek: Ἡράκλειος, romanized: Hērákleios; died 610) was a Byzantine Roman general and the father of Byzantine Roman emperor Heraclius (r. 610–641). Heraclius the Elder distinguished himself in the war against the Sassanid Persians in the 580s. As a subordinate general (or hypostrategos), Heraclius served under the command of Philippicus during the Battle of Solachon and possibly served under Comentiolus during the Battle of Sisarbanon. Circa 595, Heraclius the Elder is mentioned as a magister militum per Armeniam sent by Emperor Maurice (r. 582–602) to quell an Armenian rebellion led by Samuel Vahewuni and Atat Khorkhoruni. Around 600, he was made the exarch of Africa and in 608, he rebelled with his son against the usurper Phocas (r. 602–610). Using North Africa as a base, the younger Heraclius managed to overthrow Phocas, beginning the Heraclian dynasty, which would rule Byzantium for a century. Heraclius the Elder died soon after receiving news of his son's accession to the Byzantine throne.

Balis (Arabic: بالس), also known as Barbalissos (Medieval Greek: Βαρβαλισσός) and Barbalissus (Latin), was an ancient and medieval fortress on the Euphrates River near the ruins of the still more ancient Emar. It is particularly known for the 253 Battle of Barbalissos, where the Roman army was defeated by Sassanid Persia. The fortress town's own ruins are located at the modern Qala'at Balis (Arabic: قلعة بالس) in the Aleppo Governorate of northern Syria.

Theodosius (Ancient Greek: Θεοδόσιος, romanized: Theodósios; 4 August 583 – shortly after 27 November 602) was the eldest son of Roman emperor Maurice (r. 582–602) and was co-emperor from 590 until his deposition and execution during a military revolt. Along with his father-in-law Germanus, he was briefly proposed as successor to Maurice by the troops, but the army eventually favoured Phocas instead. Sent in an abortive mission to secure aid from Sassanid Persia by his father, Theodosius was said to have been captured and executed by Phocas's supporters a few days after Maurice. Nevertheless, rumours spread that he had survived the execution, and became popular to the extent that a man who purported to be Theodosius was entertained by the Persians as a pretext for launching a war against Byzantium. There is debate over whether this man was an imposter or genuinely Theodosius.
