  Research Notes:

“Ranimirus proles regis, Garseanes frater eius, Gundisaluus frater eius, Ferdinandus frater eius” confirmed the charter dated 17 Apr 1014 under which “Sancius…rex…cum coniuge mea regina domina Maiora” donated property to the monastery of Leire, although the absence of the brother Bernardo suggests that this charter should be redated to approximately ten years later. "Sancius…rex" recommended the rule of St Benedict to the monastery of Leire by charter dated 21 Oct 1022, subscribed by "Eximina regina mater regis, Regina domna Muma, Garsia et Ranimirus, Gundesalbus et Fernandus". The Gestis Comitum Barcinonensium names "Raimirus filius Sancii Regis Navarrorum…ex…nobilissima domina de castro…Ayunarum" when specifying that he inherited Aragon on the death of his father. The charter of "Sancius Hispaniarum rex" dated 26 Jun 1033 relating to concessions to the monastery of Oriense was confirmed by his sons (in order) "Ranimirus…Garsea…Fredinandus".

Under the division of territories organised by his father prior to his death, Ramiro received Aragon, succeeding in 1035 as RAMIRO I King of Aragon. The Historia Silense records that King Sancho granted "Haragon" to "Raymiro quem ex concubina habuerat". Although considered "king" by contemporaries, he was named in documentation "Ranimirus Sancioni regis filius", although this description was not consistently used as demonstrated by the charter dated 22 May 1035 [must be misdated, probably 22 May 1055], which records the king´s donation of the churches of San Martín de Arasanz, San Pedro de Tou, San Felix y San Juan de Aínsa to Sobrarbe San Victorián, the dating clause of which specifies "regnante me Ranimiro rege in Aragone et in Suprarbi et in Ripacurtia et ultra".

He expanded his authority southwards to include territories formerly controlled by the kingdom of Navarre, in return for conceding Navarrese supremacy. He defeated his half-brother Gonzalo and expanded Aragon eastwards by annexing Sobrarbe and Ribagorza in 1044. With this expansion, Ramiro I had assumed leadership in the struggle against the Moors on his frontiers. King Ramiro I donated the church of San Miguel "prope Calonica Baasa" to Sobrarbe San Victorián by charter dated 1035 [must be misdated] "regnante Ranimiro rege in Ripacorza, in Suprarb et in Aragon", subscribed by "Ermesenda regina…Sancio Ranimiri regis filio primogenito, Sancio Ranimiri regis filio proles Ermesendis regina…Senior Sancio Galinz in Boltania, Senior Ennecho Lobez in Buil, Senior Guelmi Serui Dei in Toleto, Senior Fortung Blaschez in Elesone". In 1054, he is alleged to have fled the battle of Atapuerca, in which his half-brother García V King of Navarre was killed by his other half-brother Fernando I King of Castile, "having lost his boots, on a horse guided only by a halter". The testament of King Ramiro I, dated 29 Jul 1059, bequeathed property to “filio meo Sancio filius Ermesendis...Sancio primogenito meo, Garsea filio meo, filia mea Taresa”, and to “domina mea Sancta Maria...super Sancte Cruçe filia mea Urraka”. The testament of King Ramiro I, dated 15 Mar 1061, bequeathed property to “Sancio filio meo filius Ermisindis qui vocata est per baptismum Gilberga...Aibar et Exabirri Iateri [ad] filio meo Sancio...filia mee Urraka cui est in Sancta Cruce...Garsea filio meo”.

He died in battle against the Moors near Barbastro. The Crónica de San Juan de la Peña records that King Ramiro was killed aged 63 in 1062 and was buried in "el monasterio de Sant Iohan de Peña" after reigning for thirty eight years. The "Corónicas" Navarras record that "el rey don Romiro" died "en Grados", in 1107. ¹
