The Suez Canal (opened 1869) solved the supreme geographic friction of 19th-century globalization: the African continent blocked direct maritime trade between Europe and Asia.
Ships sailed ~19,800 km from London to Mumbai via the Cape of Good Hope—4–6 months under sail. Monsoon dependence, piracy, provisioning stops, crew mortality. Every voyage a gamble.
Ferdinand de Lesseps' Compagnie Universelle du Canal Maritime de Suez excavated 193 km across the Isthmus of Suez (1859–1869). Connecting Mediterranean → Red Sea → Indian Ocean cut the route to ~12,800 km.
~19,000 transits/year (2023). 12% of global trade by volume. 30% of container traffic. $9B+ annual revenue for Egypt. 2015 expansion (New Suez Canal) allows two-way traffic, reduces wait.
A ditch in the desert rewired the world economy. Still does.
