Khosrow I
Shahanshah of the Sasanian Empire from 531 to 579
Khosrow I (also spelled Khosrau, Khusro or Chosroes; Middle Persian: 𐭧𐭥𐭮𐭫𐭥𐭣𐭩), traditionally known by his epithet of Anushirvan (Middle Persian: 𐭠𐭭𐭥𐭱𐭫𐭥𐭡𐭠𐭭, lit. 'the Immortal Soul'), was the Sasanian King of Kings of Iran from 531 to 579. He was the son and successor of Kavad I (r. 488–496, 498/499–531).
Inheriting a reinvigorated empire at war with the Byzantines, Khosrow I signed a peace treaty with them in 532, known as the Perpetual Peace, in which the Byzantine emperor Justinian I paid 11,000 pounds of gold to the Sasanians. Khosrow then focused on consolidating his power, executing conspirators, including his uncle Bawi. Dissatisfied with the actions of the Byzantine clients and vassals, the Ghassanids, and encouraged by Ostrogoth envoys from Italy, Khosrow violated the peace treaty and declared war against the Byzantines in 540. He sacked the major city of Antioch and deported its population to Persia. In 541, he invaded Lazica and made it an Iranian protectorate, thus initiating the Lazic War. In 545, the two empires agreed to halt the wars in Mesopotamia and Syria while continuing to fight in Lazica. A truce was declared in 557, and by 562 the fifty-year peace treaty was signed.
In 572, Justin II, the successor of Justinian, broke the peace treaty and sent a Byzantine force into the Sasanian region of Arzanene.

Why this record matters
The phrase “shahanshah of the Sasanian Empire from 531 to 579” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q207381. VIAF identifies the subject as 80838587. The Library of Congress control number is nr98013189. 3 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
