The Corsican lords

Corsica in 1200 is an island of castles and kin-groups, of mountain districts (pievi) each with its mother church, and of decayed Roman coastal towns, under an overlordship Pisa has claimed since the popes entrusted the island to its bishop in the 1070s and made him archbishop and primate in 1091.

Since 1133 (it.wikipedia: 1138) the island's six sees have been split: Aléria, Ajaccio and Sagone under Pisa; Mariana, Nebbio and Accia under Genoa. Pisa's rule works through its archbishop, its merchants and the oaths of local lords rather than through Pisan castles, and no Pisan governor or garrison in Corsica is pinned for 1200. Genoa took Bonifacio, the fortress at the southern tip that commands the strait, in 1195, beat off a Pisan attempt to retake it in 1196 and strengthened it in 1198.

The lords who hold the rest are poorly documented for these years: beyond the mountains (Pumonte) the Cinarca lineage (Cinarchesi) and the Biancolacci of the far south; this side of the mountains (Cismonte) the kin-groups the chronicler names, among them the lords of Loreto, the Cortinchi and the Amondaschi, and the lords of Cap Corse. Names and dates for 1200 are not pinned.

it.wikipedia and fr.wikipedia on the history of Corsica, fr.wikipedia on Bonifacio and Cinarca; the lineages are known mainly from Giovanni della Grossa's fifteenth-century chronicle.

What the realm holds

  • The pievi of the Pumonte, the south-west, where the Cinarca lords are dominant (thin)
  • The pievi of the Cismonte, the north and east, divided among several kin-groups (thin)
  • The six bishoprics (Church map records): Aléria, Ajaccio, Sagone (Pisan suffragans), Mariana, Nebbio, Accia (Genoese suffragans)

Allies and rivals

Pisa and Genoa each have friends among the lords; the chronicle tradition makes the Cinarca lords Pisa's men in the thirteenth century and the lords of Cap Corse Genoa's.

The realm that morning

On 1 January 1200 Corsica outside Bonifacio is held by its own lords, with Pisa's claim to overlordship standing and Genoa's colony at Bonifacio at war with Pisa at sea (no peace or truce since 1195). Which lord holds which castle that winter is not pinned.

Wealth

Livestock and chestnut woods, wine (the Nielluccio vine is credited to the Pisans), the salt and coral of Bonifacio's waters, timber, the coastal trade with Pisa and Genoa.

Military

Castle garrisons and kin followings; no host of the island. Bonifacio holds a Genoese garrison.

Threats

  • Genoa's expansion from Bonifacio
  • Pisa's attempts to retake Bonifacio (until 1217)
  • Feuds among the lineages

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.

  1. During 1200 (no dated event)The Pisan and Genoese war at sea continues round Bonifacio and the strait; no battle or truce is dated for 1200.Depends on: No peace between the two cities. Stopped by: A papal truce; the next dated settlement is Lerici in 1209 and Honorius III takes Bonifacio into his protection in 1217.

Where the sources disagree

  • The division of the Corsican sees between Pisa and Genoa is dated 1133 by fr.wikipedia and 1138 by it.wikipedia.
  • The campaign notes do not cover Corsica's lords.

Evidence: Twelfth-century Corsica is known mainly from church documents and from Giovanni della Grossa's fifteenth-century chronicle, which historians treat as legendary before about 1000 and patchy after.

On the map: The island is coloured as one block because the lordships of 1200 cannot be drawn reliably; the two lord records for the lineages give rough zones.
