Barony of Patras

1209 CE – 1276 CE (approx.) · capital Patras

The largest barony of the Principality of Achaea, centred on the port of Patras, later sold to its Latin archbishop.

Origins

When the Principality of Achaea was organised around 1209, Patras, the main port of the north-western Peloponnese, was granted as a barony with 24 knight's fiefs to William Aleman, a knight possibly of German or Provencal origin. He fortified the ancient citadel above the town.

Rule and society

The barons held the castle and city, owed service to the prince and shared the town with the Latin archbishop, who was the senior Catholic prelate in the principality. Patras was a commercial centre for silk, currants and trade with Italy, with a Greek majority under Latin lords.

Decline and legacy

Over the 13th century the archbishops acquired the baronial rights. Around 1276 the barony passed to the archbishop, creating the Latin Archbishopric of Patras, a church-ruled state that lasted until 1430.

Few sources survive for this state; details are uncertain.
