Kunaitra's command ship was heavily damaged, Kunaitra himself killed, and communications disrupted. Most military historians point to this action as the key turning point of the struggle. Atreides was ennobled after Shetiset's coronation as Baron Tantatos, and was given large estates oti the planet Enskog in recognition for his services to the Imperium (86 B.C.). Deffietrios Atreides had three sons; Pausanias (bom ca. 85 B.G.), Theseus {born ca. 81 B.C.), and Konstantinos. named for the Etnperor's father (bora 79 B.G.); from these three mea descend all die branches of the House Atreides. Pausanias succeeded to the Barony on his father's death in 58 E.G.; Theseus Atreides was ennobled as Baron Pelops in 43 E.G. during the wars of expansion conducted by Henoor I: Konstantinos or Costin Atreides became Baron Menelaus the year before he died, in 1I E.G.; Pausanias's son, Demetrios 11, was further ennobled in 6 B.C. as Count Thuestes. The family fortunes fell, however, with the assassination of Elrood I in 104, and his replacement by Alman bin Haig; a bill of attainder was brought before the Landsraad by Alman in 122, accusing Elias Atreides of supporting the exiled Emperor's forces; but Alman himself was assassinated before the bill could be acted upon. Elias Atreides was restored to his estates by Saudir IT, and reconfirmed in his titles. Elias's son, Demetrios IV, was murdered by Alman II shortly after his accession in 184, and the Atreides lands redistributed. Thomas Atreides was instrumental in restoring Elrood H in 207, and received the title Duke of Jaddua and a planetary fiefdom, both of which were attainted by Alman IV in 346, when Thomas II Atreides was executed. Alkman Atreides successfully petitioned for restoration of the County of Thuestes before the Regent Henli al-Qair in 381. Thereafter, the Atreides generally attained the status of a House Major as the imperial feudalism developed from necessity into a workable system of government.
