Rinaldo d'Este (1221–1251)

He was the son of Azzo VII d'Este, Marquis of Ferrara, from his first marriage c. 1221 to Giovanna (+1233).

Azzo VII became the leader of the Guelph forces against Frederick II Hohenstaufen, King of Germany.

[1][better source needed] Soon after the birth, Obizzo and his mother were expelled from Ferrara; they settled in Ravenna.

In 1238 Rinaldo and his wife were captured by Frederick II and died as prisoners in Apulia in 1251.

Azzo VII had three daughters but no other sons to continue his line, and thus saw in Obizzo the only chance of survival of the House of Este.
