Question: Did Ivan's brother die in battle? Passage:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the Bulgarian–Vlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.

Question: How old was the first confirmed non-English manager of Port Vale FC during peacetime? Passage:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 1953–54. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 1958–59. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.
