The Suez Canal nationalization is the transfer of ownership from the French government to the Egyptian government in return for compensations awarded to foreigners. That was done in the era of Egyptian President Gamal Abdel Nasser on July 26, 1956 due to the rejection of the World Bank financing the Egyptian government to construct the High Dam. The Suez Canal nationalization was the cause of the Tripartite Aggression carried out by France, Britain and Israel over Egypt.

The Suez Canal before the nationalization was Egypt's extorted right and nationalization returned the right back to its owners. The Suez Canal management foreign company before nationalization was a state within a state that didn't work in favor of Egypt. At the time of nationalization, The proportion of working Egyptians was only 28% and the rest were foreigners. The English or French were not to returning the channel to Egypt but were planning to extend the concession period and if they failed, they plotted to sabotage the channel before handover. Therefore, their reaction to the nationalization decision was extremely aggressive; they masterminded plots and engaged in a war represented in the tripartite aggression against Egypt in an attempt from the company and supporting countries to restore the channel. Yet, they failed to achieve that because the proud Egypt people insisted to continue fighting and decided resistance in defense of its right that was approved by all international norms and conventions. The victory was achieved and aggressor forces withdrew from the Suez Canal Zone.
