The Wikipedia article of the day for June 17, 2021 is Antiochus X Eusebes.
Antiochus X Eusebes (c. 113 BC – 92 or 88 BC) was a king of Syria during the Hellenistic period. During his lifetime Seleucid Syria was beset by civil wars, interference by Ptolemaic Egypt and incursions by the Parthians. In 95 BC, Seleucus VI killed his own half-uncle Antiochus IX, the father of Antiochus X, who took revenge by defeating Seleucus VI and driving him to his death in 94 BC. Antiochus X did not enjoy a stable reign as he had to fight three of Seleucus VI’s brothers, Antiochus XI, Philip I and Demetrius III. Antiochus XI defeated Antiochus X and expelled him in 93 BC from Antioch, the capital. A few months later, Antiochus X regained his position and killed Antiochus XI. The civil war continued but its final outcome is uncertain. Antiochus X married his stepmother Cleopatra Selene, and had several children with her, including a future king, Antiochus XIII. He probably died fighting against the Parthians in 88 BC.
