The earliest known human activity on the island dates to around the 10th millennium BC. Archaeological remains from this period include the well-preserved Neolithic village of Khirokitia, and Cyprus is home to some of the oldest water wells in the world. Cyprus was settled by Mycenaean Greeks in two waves in the 2nd millennium BC. As a strategic location in the Middle East, it was subsequently occupied by several major powers, including the empires of the Assyrians, Egyptians and Persians, from whom the island was seized in 333 BC by Alexander the Great. Subsequent rule by Ptolemaic Egypt, the Classical and Eastern Roman Empire, Arab caliphates for a short period, the French Lusignan dynasty and the Venetians, was followed by over three centuries of Ottoman rule between 1571 and 1878 (de jure until 1914).
