Walter Kaegi has convincingly argued that an Arab raid against Sardinia took place in the second half of the seventh century. This is an important contribution, because until now scholars commonly believe the first Arab raids against Sardinia to have taken place in 703. The majority of Muslim raids against the island, according to Muslims sources, is concentrated in the first half of the eighth century (703–704, 705–706, 707–708, 710–711, 732, 735, 752), at the same time of one of the most enduring period of Arab pressure against Anatolia and Constantinople.
