Battle of Nahavand
battle between Arabs and the Sassanide Empire
The Battle of Nahavand (Arabic: معركة نهاوند Maʿrakah Nahāwand, Persian: نبرد نهاوند Nabard-e Nahâvand), also spelled Nihavand or Nahawand, was fought in 642 between the Rashidun Muslim forces under An-Numan ibn Muqarrin and Sasanian army under King Yazdegerd III. Yazdegerd escaped to the Merv area, but was unable to raise another substantial army. The battle ended in a victory for the Rashidun Caliphate and the Sasanids consequently lost the surrounding cities including Spahan (Isfahan). The engagement resulted in a catastrophic defeat for the Sasanid forces and marks the end of organized Sasanid resistance. Thus opening the path for Islamic expansion into Persia and the subsequent religious transformation of the region.
The former Sasanid provinces, in alliance with Parthian and White Hun nobles, resisted for about a century in Tabaristan, the region south of the Caspian Sea, even as the Rashidun Caliphate was replaced by the Umayyads, thus perpetuating the Sasanid court styles, Zoroastrian religion, and Persian language.
Background
At the time of the death of the Islamic Prophet Muhammad in 632, the religion that he led dominated the Hejaz (western Arabia). Under the first two caliphs Abu Bakr and Umar, Islam expanded into Palestine and Mesopotamia where it respectively confronted the East Roman and Persian (Sāsānian) empires. Both were exhausted by warfare and internal dissent. With the East Roman defeat at the Battle of Yarmouk (636), the Muslim Arabs were free to turn east to the Euphrates and the Persian heartland. In November 636 a Sāsānian army was defeated at the Battle of Qadisiya, resulting in the loss of Iraq to the Muslims.
This brief starts where responsible research should: with the source description of “Battle of Nahavand” as battle between Arabs and the Sassanide Empire. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as battle between Arabs and the Sassanide Empire. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q603549. The Library of Congress control number is sh85089527. Authority coordinates are 31.583, 44.500. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. 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.
