da Canossa

A family of castellans in the hills south-west of Reggio who took their name from Canossa.

Welf VI, then holding Matilda's lands for the empire, gave them Bianello in 1160, the castle where Matilda had received Henry V in 1111. They hold the Quattro Castella hills and Rossena, among the old Matildine strongholds that the commune of Reggio has not yet absorbed.

it.wikipedia (Castello di Bianello): in 1160 Duke Welf (VI) ceded the fortress to Guido di Canossa, the start of the Canossa branch of Bianello. Rossena and Monte Vetro were also held by the Canossa family before their later holders; dates not given. The head of the family in 1200 was not found.

Overlord

The holder of the Matildine lands: Welf VI granted Bianello in 1160; the claim has since passed to the emperor (bought from Welf in 1173-1174), to Philip of Swabia (1195), and is contested by Innocent III.

What it holds

  • Bianello, the chief of the four castles of Quattro Castella (since 1160)
  • Monte Vetro, one of the four castles (Canossa first, then the da Fogliano and Parma in later times)
  • Rossena, the castle facing Canossa (first held by the Canossa family; dates not given)

How it was acquired

Welf VI's grant of Bianello in 1160.

Allies and rivals

Reggio's commune presses on them; the dalla Palude hold Monte Zane, another of the four castles.

How things stand that morning

The da Canossa hold Bianello and the neighbouring castles as heirs of an imperial grant, outside the commune's direct rule.

Wealth

Hill farms, wood and the roads from the Reggio plain to the Enza and the Apennines.

Military

Hill castles; no figures.

Threats

  • The commune of Reggio
  • The papal claim to Matilda's lands

Places of note

  • Bianello: The family's castle since 1160
  • Rossena: Castle facing Canossa

Where the sources disagree

Evidence: The 1160 grant is on it.wikipedia; the family's members and full holdings in 1200 were not found.

On the map: The comune of Quattro Castella stands for the four castles; Monte Zane among them was the dalla Palude's.
