After the First Crusade, western settlers established states in which region, and what was the chief of them called?
In North Africa, the chief of them being the Kingdom of Carthage
In southern Spain, the chief of them being the Kingdom of Cordoba
Along the eastern Mediterranean coast, the chief of them being the Kingdom of Jerusalem✓Bonne réponse
Along the eastern Mediterranean coast, and they lasted until the end of the Middle Ages
Explication
The territory held after the first expedition formed a narrow strip along the eastern seaboard of the Mediterranean, and the state centred on the captured city was the chief of the group. The version that runs them to the close of the medieval period fails because the last of these mainland holdings was lost well before the Middle Ages ended.
