The first written source shows Cyprus under Assyrian rule. Cyprus gained independence for some time around 669 but was conquered by Egypt under Amasis (570–526/525). The island was conquered by the Persians around 545 BC. During the siege of Tyre, the Cypriot Kings went over to Alexander the Great. Full Hellenisation only took place under Ptolemaic rule. Phoenician and native Cypriot traits disappeared, together with the old Cypriot syllabic script. A number of cities were founded during this time, e.g. Arsinoe that was founded between old and new Paphos by Ptolemy II.
