In 1936, the largest Arab uprising broke out in the country. The Arabs were furious at the issuance of entry visas to Jews fleeing Nazis to Mandatory Palestine. The support of the English authorities in connection with the emigration of the Jews diminished. The British reduced the issuance of visas. Despite this, unrest among the Arabs gained momentum, and they boycotted the port of Jaffa. The British very quickly built an alternative port in north Tel Aviv. This tension developed into the great Arab uprising brutally suppressed by the British authorities with the outbreak of World War II in 1939. Regular soldiers' companies entered Jaffa. The operation was called "Anchor". The part of the city was depopulated, and buildings were demolished in 1939. After the War of Independence of 1948 and after the absorption of Jewish refugees from Arab countries, plans were made to redevelop ruined Jaffa, which became slums and brothels. In parallel with the preparations for rehabilitation and renovation, excavations were conducted. Archaeologists chose this excavation area on the hillside in the centre of the city for a reason. In the bronze age, people always build towns in a high place near essential trade routes and near water sources. All these conditions existed in old Jaffa, and only after almost five centuries, the city "descended" to the sea when a maritime trade relationship developed. Therefore, excavations at the top of the slope can reveal the ancient history of the city. The excavations confirmed many biblical stories. Researchers found the city gates date from the time of Pharaoh Ramesses II. He was one of the legendary Egyptian pharaohs. During the reign of Ramesses II, the first peace treaty in human history was signed. It was a peace treaty with the Hittite kingdom. During the reign of Ramesses II, the construction of the famous temples in Luxor began, and the coastal plain of Canaan (modern Israeli shores) became a series of important trading cities of the ancient world, including Old Jaffa.
