The Sousa are the greatest kindred of Entre Douro e Minho and the first house at court.
On 1 January 1200 their head is Gonçalo Mendes, mordomo-mor since 1192: he runs the king's household and confirms every royal charter after the king. He holds the royal tenência of Basto, the hill district on the Tâmega, and was tenente of Celorico da Beira on the Beira frontier in 1196. His father Count Mendo, often named as head of the house, died in 1192.
His brothers have shared the court offices (Rodrigo was alferes-mor until 1198) and the northern tenências. The family's own land is a web of honras, quintãs and church patronage in the Terra de Sousa round their monastery of Pombeiro.

Overlord
Sancho I of Portugal
What it holds
- The office of mordomo-mor of the royal court (since 1192)
- Tenência of Basto (attested 1195-1211): the king's castle, justice and dues in the Terra de Basto
- Tenência of Celorico da Beira (attested 1196; not pinned for 1 January 1200)
- Family honras, quintãs and patronage of churches and monasteries in the Terra de Sousa and round Felgueiras, with the patronage of the monastery of Pombeiro
How it was acquired
Headship and the office of mordomo-mor on his father's death in 1192. Basto is a Sousa-linked tenência: his uncle by marriage Vasco Fernandes de Soverosa held it to 1186 and his father from 1186 to 1192.
Allies and rivals
Allied by marriage with the Ribadouro (Lourenço Soares) and the Soverosa (Gil Vasques). The rising rival lineage is the Riba de Vizela, whose Martim Fernandes replaces him as mordomo-mor in June 1211. In 1200 the Sousa are wholly the king's men.
How things stand that morning
At the head of the royal household and holding Basto; the strongest family at court.
Wealth
Dues, rents and justice of the Basto district; the family honras, free of royal officers; church patronage in the Sousa valley; the profits of the mordomia.
Military
The Sousa household knights and the men of Basto. No figures.
Threats
- A shift of royal favour toward the Riba de Vizela
- Raids on the Beira frontier if he still holds Celorico
- The heir Afonso, who will break with the Sousa in 1211
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- 1200 (month not pinned)During the heir's grave illness Sancho I visits Santa Senhorinha de Basto and grants the surrounding land to that church; Gonçalo Mendes, as lord of Basto, sets the boundary stones.Depends on: The heir's illness as recorded. Stopped by: Nothing in play.
Places of note
- Monastery of Pombeiro: Sousa family monastery (patronage), burial church of the house
Where the sources disagree
- Mendo Gonçalves de Sousa, often named as head of the house, died in 1192 (pt.wikipedia after Sottomayor-Pizarro); his son Gonçalo Mendes II is head on 1 January 1200.
Evidence: Office and tenências from Calderón Medina's charter lists and the Sousa genealogies. Basto is firm; Celorico da Beira is attested for 1196 only; the honras are known by name, not by bounds.
On the map: Basto follows the two modern concelhos named for it; the Sousa honras were scattered estates, not a block.
