Casa de Castro

The medieval House of Castro took its name from Castrojeriz in Burgos and became a major force at the Castilian and Leonese courts. Its rivalry with the Lara family shaped the minority of Alfonso VIII in the twelfth century. The surname also developed independently from many places called Castro, from Latin castrum, a fortified site; the noble house is one particular history within that wider name.

The family’s connection to the Ribeiro can be traced before its fourteenth-century prominence. Fernando Gutiérrez de Castro held the royal tenancy of Ribadavia in 1205, 1228 and 1231; his son Andrés is recorded there in 1251–1254. A tenencia was authority exercised for the crown, which must be distinguished from the later hereditary lordship of the Sarmientos. The Galician Castro power base extended through Lemos and Sarria, and Esteban Fernández de Castro’s marriage to Aldonza Rodríguez de León, a granddaughter of Alfonso IX, strengthened the family’s royal connections. Monforte de Lemos became its best-known seat.

Esteban Fernández de Castro held the offices of Adelantado Mayor de Galicia and Pertiguero Mayor de Santiago. The first concerned royal government and justice; the second represented military authority in the temporal lands of Compostela’s church. These were offices exercised within overlapping jurisdictions, not ownership of an undivided Galician kingdom. Toroño, in southern Galicia around Tui, should likewise not be treated as a synonym for the whole Ribeiro.

His grandson Pedro Fernández de Castro, el de la Guerra, was a leading fourteenth-century noble and commander under Alfonso XI. After his father’s death at Monforte in 1304, Pedro spent his early years in Portugal and later recovered the family position in Galicia. He fought at the battle of Río Salado in 1340 and died during the siege of Algeciras in 1343. The celebrated story of the Marinid sultan’s golden spurs belongs to accounts of his martial reputation; his burial at Santiago links that reputation to an enduring monument.

Pedro Fernández de Castro "el de la Guerra" fathered four children who would shape the history of two kingdoms. By his wife Isabel Ponce de León, he had Fernando — who would become a leading Castro lord in Galicia — and Juana, who married Pedro I of Castile. By his mistress, a Portuguese noblewoman named Aldonça Lourenço de Valladares, he had Álvaro — who would become Constable of Portugal — and Inês.

Inês de Castro arrived at the Portuguese court around 1340 as a lady-in-waiting to Constance of Castile, the bride of Prince Pedro, heir to the Portuguese throne. Pedro fell in love with the Galician noblewoman. The affair endured beyond the death of Constance in 1345, producing four children, and drew the Castro family — through Inês's brothers Fernando and Álvaro — dangerously deep into Portuguese court politics. King Afonso IV, fearing the Castro clan would drag Portugal into the Castilian succession crisis, ordered Inês killed. On 7 January 1355, three courtiers murdered her in Coimbra, where she had lived near Santa Clara.

Pedro became king in 1357. On 18 June 1360 he solemnly declared that he and Inês had married secretly in 1354, asserting the legitimacy of their children. The declaration survives in the Arquivo Nacional da Torre do Tombo. It records the king’s claim; it does not establish the later story of a crowned corpse. Their sculpted tombs at Alcobaça, now facing one another across the transept, preserve the royal commemoration. Literary retellings by Camões and later writers gave the tragedy a second life beyond its dynastic setting.

Fernando Ruiz de Castro, son of Pedro Fernández de Castro, was a leading supporter of Pedro I during the Castilian civil war. His offices and lordships connected Lemos, Sarria and the lands of Compostela with the struggle for the crown. His allegiance had not been unchanging: Pedro’s abandonment of Fernando’s sister Juana after their marriage in 1354 helped produce a temporary break before Fernando returned to the king’s side.

After Pedro I’s death at Montiel in March 1369, resistance continued in Galicia. Fernando allied with Fernando I of Portugal, whose claim to the Castilian throne gave the defeated faction a new royal patron. Towns, nobles and ecclesiastical powers made different choices; Galicia was not a single united state unanimously refusing Enrique II. The continued war explains why later grants to the Sarmiento and Biedma houses were politically important.

The phrase toda la lealtad de España, traditionally associated with Fernando’s tomb at Bayonne, captures the memory of this commitment. It is a memorial judgement, not a reason to reduce the civil war to virtuous Galicians against foreign newcomers.

Enrique II appointed Pedro Ruiz Sarmiento Adelantado Mayor de Galicia in 1370. The campaigns against Fernando de Castro culminated in defeat at Porto de Bois, near Palas de Rei, in 1371. This was a turning point in the remaining Petrist resistance. It was not a repetition of the family death at Monforte in 1304: those were different places and generations.

The settlement with Portugal and further changes in Anglo-Castilian relations narrowed Fernando’s options. He eventually went to English-held Bayonne, where he died in 1377. His exile ended this phase of Castro leadership, but did not extinguish every branch of the house; later Castro-Osorio generations again held major Galician titles.

The crown redistributed particular offices and lordships among its supporters. Sarmiento received Ribadavia in 1375, while other grants favoured the Biedma and Andrade houses. Each transfer had its own date and territory. For the Ribeiro, this history explains the rise of the Sarmiento seat beside a continuing landscape of monastic, municipal and military-order rights.

The hill above Santa María de Castrelo de Miño carries a history older than the noble House of Castro. Castrelo is a diminutive of castro, a fortified place; the similarity of names does not identify the parish as a foundation or possession of that lineage. Archaeology and the monastery’s records belong to the local story in their own right.

Sancho Ordóñez, king in Galicia from 926 to 929, is associated with the monastery and its burial tradition. His widow Goto Muñoz became a nun and appears as abbess in the tenth century. He was one of several medieval kings who ruled Galicia, rather than its first or last independent king. Sancho I of León died in 966: the account of poisoning linked to Count Gonzalo Menéndez belongs to the chronicle tradition, and should not be recast as a securely proven murder in 969.

Read with Ribadavia and Cartelle, Castrelo helps explain a landscape of river crossings, monasteries, castles and parish rights. Its later association with the Hospitallers adds another institution to that history. These places were connected by travel and exchange, while retaining distinct jurisdictions and timelines.

Six blue roundels (roeles de azur) on silver, arranged in three pairs, form the recurring Castro device. Later shields combine it with other families’ arms, including the wolves of Osorio. Inscriptions, dates and building history help identify the particular household represented.

A documented comparison survives at Bujalance, Córdoba. The Instituto Andaluz del Patrimonio Histórico’s record of a Luna–Castro–Córdoba shield identifies the Castro quarter by those six blue roundels. This object outside Galicia confirms a heraldic pattern; establishing the owner and genealogy of a Galician carving still requires evidence from that monument and household.
