Answer:
A crisis in Egypt over the Suez Canal.
Step-by-step explanation:
The Suez Crisis took place in 1956, and it involved many of the world's most powerful countries, pushing the world to the brink of World War III. The Suez Crisis was an invasion of Egypt by Israel, followed by the United Kingdom and France. These powers wanted to regain Western control of the canal, as well as remove president Nasser, who nationalized the canal. The crisis was solved, to a great extent, by the efforts of the United Nations.
