The Egyptians were the first to attempt a mission of exploration in the Red Sea. In the Bible, the story of Moses tells how the son of a slave woman leads the Israelites across it to freedom, by using the power of God to part the waters. However, it was a Greek sailor, Hippalus, who conferred an international dimension upon the Red Sea in his manifesto on the voyage of the Eritrea Sea and thus opened it up to an immense and exclusive trade with Asia. It was only from the 15th century onwards that Europe began to show interest in this area. In 1798, France charged General Bonaparte with invading Egypt and capturing the Red Sea. Although he failed in his mission, the engineer J.B. Lepere, who took part in it revitalised the plan for a canal which had been envisaged during the reign of the Pharaohs. The Suez Canal was opened in November 1869. At the time, the British, French, and Italians shared the trading posts. The posts were gradually dismantled following the First World War. After the Second World War, the Americans and Soviets exerted their influence whilst the volume of oil tanker traffic intensified. However, the Six Day War culminated in the closure of the Suez Canal from 1967 to 1975. Still today, in spite of patrols by the major maritime fleets in the waters of the Red Sea, the Suez Canal has never recovered its supremacy over the Cape route, which is believed to be less vulnerable.
