Nicosia has been in continuous habitation since the beginning of the Bronze Age 2500 years BC, when the first inhabitants settled in the fertile plain of Mesaoria. Nicosia later became a city-state known as Ledra or Ledrae, one of the twelve kingdoms of ancient Cyprus built by Achaeans after the end of the Trojan War.  Remains of old Ledra today can be found in the Ayia Paraskevi hill in the south east of the city. Only one king of Ledra is known: Onasagoras. The kingdom of Ledra was destroyed early. Under Assyrian rule of Cyprus, Onasagoras was recorded as paying tribute to Esarhaddon of Assyria in 672 BC. By 330 BC, Ledra was recorded to be a small unimportant town. It is thought that the settlement was economically and politically dependent on the nearby town of Chytri. The main activity of the town inhabitants was farming. During this era, Ledra did not have the huge growth that the other Cypriot coastal towns had, which was primarily based on trade.
