Count of Ossero

Ossero (Osor), the bishop's town on the narrow cut between Cres and Lošinj, is the head of both islands, and its count governs them for Venice.

Venice lost Ossero, with Arbe and Pag, when its fleet was beaten in 1190 in the war for Zara, but by 1198 a Venetian noble, Ruggero Morosini, was count of Ossero again. On 1 January 1200 the islands are Venetian, as far as the sources show. Cherso (Cres) is a harbour village under Ossero; the short passage through Ossero's canal makes the town a port of call on the Kvarner route.

Ruggero Morosini, count of Ossero in 1198, when he also became Venice's rector of Pola; he died as count before March 1208, when Venice granted the county to his sons Robert, Peter (or John) and Andrew, so he very probably holds it that winter

Places of note

  • Ossero: The bishop's town and seat of the count.
  • Cherso: Harbour village on Cres under Ossero.

Where the sources disagree

  • Duplicates Count of Ossero on the Northern Italy map (same ground, same realm, same holder): keep one.

Evidence: The 1190 loss rests on one source; the count is attested in 1198 and by the 1208 grant to his sons.

On the map: Drawn whole. Duplicates Count of Ossero (Northern Italy map): the compiler should keep one.
