On November 16, 1869, Lesseps finished building the opened canal. The inauguration took place the next day. In late 1875, Benjamin Disraeli, who served as Prime Minister of Great Britain for the second time, acquired a 44% stake in the channel, in favor of the English crown by a money move on the Stock Exchange. The Egyptian debt had climbed and Disraeli took the change of buying Egyptian external debt stock of the Canal, and the rest was acquired from the French through the same stock exchange.
The Suez Canal Crisis was also known as the Sinai War. It was a massive Israeli invasion of Egypt which had the joint support of Britain and France, because Egyptian President Gamal Abdel Nasser nationalized the Suez Canal, which belonged to Britain.
First, Egypt blocked the passage of ships loaded with oil from Saudi Arabia and the Emirates towards Israel, Europe and the United States.
Britain had controlled the canal after France built it. Israel was increasingly threatened by a possible Egyptian invasion, with the help of the Soviet Union. Israel invaded Egypt and the next day France and Britain issued a joint statement to Nassar of Eygipt and began to bomb Cairo.
