La Sardegna dei Giudici
Medieval history of Sardinia from the Byzantine empire until the Spanish Aragonese took control of the island. It was the time of the rule of the Giudici in Sardinia, the influence of Pisa and Genua and the popes trying to gain control over Sardinia. A very fine written history by Gian Giacomo Ortu.
