Malik-Shah I
The Arab World and East Asia at the time, though generally more enlightened, also suffered from assassinations at this point in history, such as Seljuk Turk leaders Alp Arslan (November 24th, 1072) and his son Malik-Shah I (November 19th, 1092), as well as Japanese Shogun Oda Nobunaga (June 21st, 1582), who was forced to commit seppuku in the Honno-ji Incident.
