 In 1078, a document from the Diocese of Roda in Aragon, names as the most powerful rulers in Christendom "Henry, ruling ("imperante") the Romans; Philip, the Franks; [and] Alfonso, the Spaniards", a possible allusion to Alfonso's imperial rank.On at least four occasions in his dating clauses (1081, 1086, 1092, and 1093), Sanchor Ramírez, ruler of Aragon and Pamplona, referred to Alfonso VI as "imperatore domino Adefonso" ("the lord emperor Alfonso") ruling either "in Legione" ("in León") or "in Leone et in Castella atque in Toleto" ("in León and in Castile and also in Toledo").In the clause of 1086 and also in dating clauses of the Aragonese king for 1087, 1089, 1090, and 1093 wherein Alfonso's only title is "rex" (king), the Leonese king is named before the king whose charter it is, a clear indication that Sancho recognised an order of precedence or hierarchy which placed Alfonso at the top.
