Afonso wed Maud of Savoy, daughter of Amadeus III, Count of Savoy, and sent ambassadors to Rome to negotiate with the Pope.

The war which followed was ended by Afonso III consenting to wed Beatriz de Guzmán, illegitimate daughter of Alfonso X, and to hold Algarve as a fief of Castile.

Afonso married in 1146 Mafalda or Maud of Savoy ( 1125 – 1158 ), daughter of Amadeo III, Count of Savoy, and Mahaut of Albon.

After the death of his father, Peter took the side of his sisters Mafalda, Sancha and Theresa, in their quarrel with his elder brother, now King Afonso II, over inheritance of the castles of Seia,

Philip then remarried, to Princess Matilda of Portugal, daughter of Afonso I, the first King of Portugal, and Maud of Savoy.

Sancho I (), nicknamed " the Populator " (), King of Portugal ( 11 November 1154 – 26 March 1212, both Coimbra ) was the second but only surviving legitimate son and fourth child of Afonso I of Portugal by his wife, Maud of Savoy.

After a string of proposals from various members of European ruling families, including Charles II of England, Afonso VI of Portugal, and Charles Emmanuel II of Savoy, she eventually fell in love with Antoine Nompar de Caumont and scandalised the court of France when she asked Louis XIV for permission to marry him, as such a union was viewed as a mésalliance.

Philip then remarried, to Infanta Matilda of Portugal, daughter of Afonso I, the first King of Portugal, and Maud of Savoy.

Infanta Urraca of Portugal (; ( 1151 – 1222 ) was a Portuguese infanta ( princess ), daughter of Afonso I, 1st King of Portugal and his wife Maud of Savoy.

Afonso married Infanta Urraca of Castile, daughter of Alfonso VIIIof Castile and Leonora of England, in 1206.

In 1309, Afonso IV married Infanta Beatrice of Castile, daughter of King Sancho IV of Castile by his wife Maria de Molina.

Afonso IV was not happy to see his daughter abused, and started a war against Castile.

Afonso married Beatrice of Castile ( 1293 – 1359 ) in 1309, daughter of Sancho IV, King of Castile, and María de Molina and had four sons and three daughters.

To secure his position as regent, Peter had Afonso marry his daughter, Isabella of Coimbra, in 1445.

Isabella died in 1455 and Afonso married again ( although not recognized by the Papacy ) in 1475, this time to Joanna of Castile ( known as " La Beltraneja "), daughter of Henry IV of Castile and Joan of Portugal.

The city is also famous for the Convento de Jesus ( now known as the City Museum " Santa Joana "), built in the 15th century, which contains the tomb of the daughter of Afonso V, St. Joana, who died in 1490.

Her firstborn, a daughter named Isabella, married Afonso of Portugal, forging important ties between these two neighboring countries and hopefully ensuring future alliance, but Isabella soon died before giving birth to an heir.

* April 25 – Infanta Branca of Portugal, daughter of King Afonso III of Portugal and Urraca of Castile ( d. 1321 )

Hostilities between Portugal and the reunited kingdoms of León and Castile were terminated in 1297 by a treaty of alliance, in accordance with which Ferdinand IV of Castile married Constance, daughter of Dinis, while Afonso, son of Denis, married Beatrice of Castile, daughter of Ferdinand.

Peter, the heir, afterwards married Constance, daughter of the duke of Peñafiel ( near Valladolid ), and Afonso IV brought a strong Portuguese army to aid the Castilians against the Moors of Granada and their African allies.

An unwise foreign policy simultaneously injured the royal prestige, for Afonso married his own niece, Joanna, daughter of Henry IV of Castile, and claimed the kingdom in her name.

In 1165 he married Urraca, daughter of Afonso of Portugal.

King Afonso III of Portugal had to surrender, but he gained an agreement by which, after he consented to marry Alfonso X's daughter Beatrice of Castile, the land would be returned to their heirs.

* Afonso I becomes Count of Portugal.

* June 24 – Battle of São Mamede: King Afonso I of Portugal ( then Count of Portugal ) defeats his mother, Teresa of León, and gains control of the county, which thus becomes de facto independent.

After three years of war against Urraca and other rival claimants to the throne of León, Count Henry himself died in 1112, leaving his widow Theresa to govern Portugal north of the Mondego during the minority of her infant son Afonso: south of the Mondego the Moors were still supreme.

The leader of such revolt was the Count Afonso Henriques ( later king Afonso I ) which had inherited the second County of Portugal ( Condado Portucalense ) and gained control of it after defeating his mother, Countess Teresa.

* Teresa Sánchez, who married Dom João Afonso de Menezes ( died 5 May 1304 ), 1st Conde de Barcelos in Portugal, the first Portuguese hereditary Count, 4th Lord of Alburquerque in Castille and 29th Mordomo-Mór of Portugal, and had female issue, and Rui Gil de Vilalobos, and had female issue

In 1246 recalcitrant nobles invited Sancho's brother Afonso, then living in France as Consort Count of Boulogne, to take the throne.

In 1464, the title of Count of Guimarães is given to Fernando II, son of the Duke of Braganza, by King Afonso V ( which was later renovated in 1475 ).

In 1442, King Afonso V established the hereditary dukedom of the Duchy of Braganza, for his uncle Afonso, Count of Barcelos, becoming one of the oldest fiefdoms in Portugal.

Her son and heir, Afonso, defeated Teresa's troops at the Battle of São Mamede near Guimarães and led her, along with the Count of Traba and their children, into exile in the kingdom of Galicia, near the Portuguese border, where the Traba had founded the monastery of Toxas Altas.

Their children were: Hugh I, Duke of Burgundy ( 1057 – 1093 ); Odo I, Duke of Burgundy ( 1058 – 1103 ); Robert, bishop of Langres ( 1059 – 1111 ); Helie, a nun ( b. 1061 ); Beatrice ( b. 1063 ), married Guy I, count of Vignory ; Reginald, abbot of St Pierre ( 1065 – 1092 ); Henry, Count of Portugal ( 1066 – 1112 ), who became a vassal of León and ruler of the county of Portugal in 1093-his son would be Afonso Henriques, first king of Portugal
