Gherardesca

The greatest comital house of the Pisan Maremma, descended from Count Gherardo of the tenth century, lords of castles from the Val di Cecina to the Cornia and founders of the abbeys of San Giustiniano di Falesia at Piombino (1022) and Serena.

The house split into branches in the mid-eleventh century; by the late twelfth century the Dizionario Biografico counts three groups named after their Maremma castles: Donoratico, Castagneto and Segalari. They are Pisan citizens and leaders in the city: Count Tedice of Castagneto was Pisa's first podestà (1190-92) and held the office again until 10 April 1199. Their rivalry with the Visconti is one of the fault lines of Pisan politics.

Confidence
medium

Treccani DBI: Tedice was podestà of Pisa 29 July 1190 to 30 May 1192 and 9 April 1197 to 10 April 1199; whether he had children is unknown, and the thirteenth-century counts of Donoratico seem to descend from him. The DBI on Ugolino della Gherardesca names Ugolino's grandfather Ottone, of whom only the name is known.

Overlord

The Empire; Pisan citizens and leaders in the commune.

What it holds

  • Castagneto, Donoratico, Segalari and Bolgheri on the coastal hills of the Maremma
  • Sassetta [Gherardesca in the twelfth century; later the Orlandi's: not pinned for 1200]
  • Montescudaio, Guardistallo, Riparbella and Casale above the Cecina [castles listed as theirs in later inventories; holders in 1200 not pinned]
  • Rights and patronage over the abbeys they founded (San Giustiniano di Falesia, Serena)
  • Earlier lords of Campiglia (half given to the archbishop of Pisa in 1139; Pisan from 1158) and founders of the mining castle of Rocca San Silvestro, held by the Della Rocca in the twelfth century

How it was acquired

Inherited lordship from the tenth century; the castle of Donoratico held in fief already by the founder (it.wikipedia). Their ties with Pisa date from the late eleventh century.

Allies and rivals

Leaders of the counts' side in Pisa against the Visconti; neighbours of the Aldobrandeschi (Suvereto) and of the bishop of Volterra (Val di Cecina).

How things stand that morning

The counts hold their Maremma castles as Pisan citizens; their head in city politics, Tedice, has just left the podesteria (April 1199), and the city cannot agree on a successor. Which branch holds which castle on 1 January 1200 is not pinned.

Wealth

Rents and dues of the Maremma castles, pasture and woods, salt marsh and the coast; earlier the Campiglia mines.

Military

Castles on the coastal hills; their knights serve in the Pisan host. No numbers.

Threats

  • The Visconti party in Pisa
  • Pisa's own growing control of the Maremma

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. Spring 1200The counts' party and the Visconti block the election of a Pisan podestà.Depends on: The feud continuing. Stopped by: A compromise.
  2. Beyond 1200: May 1208Tedice takes part in the embassy that reconciles Pisa with Innocent III; on 26 April 1209 he is at Lerici for a truce with Genoa.

Places of note

  • Bolgheri: Castle of the Bolgheri branch
  • Donoratico: Castle that gives the thirteenth-century counts of Donoratico their name
  • Segalari: Castle of the Segalari branch [coordinates approximate]

Where the sources disagree

  • it.wikipedia (Della Gherardesca) says a Tedice of Castagneto was Volterra's first podestà; the DBI on Tedice does not say so. Not used.

Evidence: Tedice is well dated; the branches' heads and the castle-by-castle holdings in 1200 are not.

On the map: The two blocks follow the castles later listed as the family's; branch by branch holdings in 1200 are not pinned.
