The Amu Darya/Oxus frontier region near where Alp Arslan was mortally wounded in 1072.
The Oxus formed a major geographic boundary in Central Asian and Islamic history, linking Transoxiana, Khurasan, and steppe-frontier politics.
Alp Arslan died after being wounded by a captive or defeated opponent during an eastern campaign. The exact local details vary in narrative sources, so IronCodex uses the broader Oxus region cautiously.
The place matters here because the death of a victorious sultan came not in Anatolia after Manzikert but on the empire’s eastern frontier.
