Tjeker
The Tjeker or Tjekker were one of the Sea Peoples.
Known mainly from the Story of Wenamun, the Tjeker are also documented earlier, at Medinet Habu, as raiders defeated by Pharaoh Ramesses III of Egypt in years 5, 8, and 12 of his reign. They are thought to be the people who developed the port of Dor in Canaan during the 12th century BCE from a small Bronze Age town to a large city.
