Suez Canal
The artificial waterway across Egypt, opened in 1869, that linked the Mediterranean to the Red Sea and became the strategic lifeline of the British Empire.
For nearly four thousand years, ships sailing from Europe to Asia had to go all the way around Africa. The Suez Canal erased that detour. Cut through about 120 miles of Egyptian desert and opened on November 17, 1869, it joined the Mediterranean to the Red Sea and shortened the voyage from London to Bombay by roughly 4,500 miles. A ribbon of water in the sand became one of the most valuable strips of real estate on Earth.
A French idea Britain came to own
The canal was a French project. Ferdinand de Lesseps, a former diplomat with a genius for promotion, won a concession from Egypt's ruler, raised the capital, and drove the digging for a decade, relying on forced Egyptian labor in the early years. The 1869 opening was a spectacle, with the French Empress Eugenie leading a flotilla of decorated ships through the new channel. London had dismissed the scheme as a fantasy and refused to invest. Then reality set in. By the 1870s most ships using the canal flew the British flag, and the shortcut had become Britain's fastest route to India, the jewel of its empire. In 1875, when the spendthrift Khedive Ismail went broke, Prime Minister Benjamin Disraeli pounced, borrowing 4 million pounds from the Rothschilds to buy Egypt's 44 percent stake. Britain now half-owned the canal it had mocked.
The lifeline of empire
Owning shares was not the same as holding the ground. When a nationalist revolt threatened the canal zone in 1882, Britain invaded and occupied Egypt, beginning a grip that lasted, in one form or another, for over seventy years. The waterway became known as the lifeline of empire: through it flowed the troops, mail, and trade that stitched London to India, Australia, and the Far East. For the Royal Navy and the merchant fleet alike, Suez was the difference between a three-week passage and a two-month one. Control of it shaped British strategy through both world wars, which is precisely why letting it go was unthinkable.
The chokepoint that still bites
The canal outlived the empire it served. In 1956 Egypt's Gamal Abdel Nasser nationalized it, and a botched British, French, and Israeli invasion, the Suez Crisis, ended in humiliating retreat under American pressure, a moment often marked as the end of Britain as a great power. Egypt has run the canal ever since. It is still a global chokepoint: in normal years around 12 percent of world trade passes through it, and in March 2021 a single grounded container ship, the Ever Given, wedged sideways and jammed the canal for six days, freezing billions of dollars in trade a day. Since late 2023, missile and drone attacks by Yemen's Houthis on Red Sea shipping have pushed much of that traffic onto the longer route around Africa, and the canal's share of Asia-Europe trade has yet to recover. A ditch in the desert that Britain once dismissed still helps decide what the world pays for almost everything.
