Quick Summary

The Constantinople Convention of 1888 established the international status of the Suez Canal. This agreement declared that the canal should be accessible to ships of all nations during both peace and war. It also prohibited acts of hostility within the canal's waters and the construction of fortifications along its banks. While Great Britain did not sign the convention until 1904, the principle of free passage through this vital waterway remains a cornerstone of international maritime law. The Suez Canal itself is a sea-level waterway in Egypt connecting the Mediterranean Sea and the Red Sea, significantly shortening maritime routes between Europe and Asia.12

The British occupation and the Protectorate (1882–1922)
In 1888 the Convention of Constantinople (Istanbul) provided that the Suez Canal should always be open to ships of all countries, in war and peace alike. This was, however, a statement of principle rather than fact; without British cooperation it remained a dead letter.
