Biography[]
John of Gallura was born in 1229, the son of Ubaldo I of Cagliari. He was nominated to succeed his father on his death, but Enzo of Sardinia took over both Logudoro and Gallura for the Hohenstaufens. In 1254, John joined Pisa in its attack on John of Cagliari, and he sided with the Republic of Pisa during its wars with the Guelphs and the Ghibellines on mainland Italy. He died in Pisa in 1275, and all of his possessions passed to the republic.
