Title:
Normans

Context:
The rapid Anglo-Norman conquest proved more important than it seemed. The island occupied a key strategic position on the maritime lanes to the Holy Land, whose occupation by the Christians could not continue without support from the sea. Shortly after the conquest, Cyprus was sold to the Knights Templar and it was subsequently acquired, in 1192, by Guy de Lusignan and became a stable feudal kingdom. It was only in 1489 that the Venetians acquired full control of the island, which remained a Christian stronghold until the fall of Famagusta in 1571.

Question:
When did the Venetians take total control of Cyprus?

1489
