Bishops' city lordships · Kingdom of Portugal · as at first light, 1 January 1200

Porto

The bishop of Porto is lord of the city at the mouth of the Douro.

In 1120 Countess Teresa gave Bishop Hugo and his successors the city and its district by right of inheritance with temporal jurisdiction, and in 1123 Hugo gave the town its foral. The bishops keep the city until 1406. Porto is a rising port of merchants and seamen, and the king, who holds Gaia across the river, would like its tolls; the bishop's lordship is a standing grievance between crown and church.

Who holds it

Name
Martinho Rodrigues
Title
Bishop of Porto
Since
1191 (some lists 1190)
Confidence
high

Bishop until 1235. He quarrelled with Sancho I over church rights more than once: in one round the king seized his goods and he fled, until Innocent III's intervention restored him; in a later round he was imprisoned, escaped to Rome, and made peace with the dying king in 1209. Whether a quarrel is open on 1 January 1200 is not pinned.

What it holds

  • Porto and its termo: lordship, justice, rents and the town's foral (granted 1120, foral 1123)
  • Dues on the river traffic at Porto (shared or disputed with the crown)

How it was acquired

Donation of Countess Teresa to Bishop Hugo in 1120.

How things stand that morning

Held by the bishop, in a lordship the king resents.

Wealth

The Douro port: tolls on ships and goods, fish, salt and wine traffic; rents of the city.

Threats

  • Sancho I seizing the bishop's goods and driving him out, as he does at some point in these years
  • Townsmen backing the king against the bishop

Advocates and rivals

King Sancho I, in conflict with Bishop Martinho; the merchants and seamen of Porto; the crown's rival landing at Gaia across the Douro.

Where the sources disagree

Evidence: The 1120 grant is well attested; the dating of the first quarrel with Sancho I is not pinned.

On the map: Drawn as the modern concelho of Porto, close to the medieval city and its termo.
