The idea of a canal connecting the Mediterranean and Red Seas across the Isthmus of Suez had been considered periodically since antiquity, but the modern Suez Canal's actual construction was driven primarily by Ferdinand de Lesseps, a French former diplomat who secured concession rights from Egypt's ruler, Said Pasha, in 1854 and formed the Suez Canal Company to finance and build the canal, with construction proceeding from 1859 to 1869, employing, particularly in its early years, a large forced labor system (the corvée) of Egyptian workers under conditions that have drawn significant historical criticism, before international pressure led to a shift toward paid labor and increased mechanization for the project's later stages.
Britain's government was notably skeptical of and, for much of the project's early development, actively opposed to the canal, viewing it partly as a French geopolitical initiative that could threaten British commercial and strategic interests built around its established maritime trade routes around Africa's southern tip and its dominant position in global shipping more broadly. Despite this opposition, the canal opened successfully in November 1869, and its practical value — dramatically shortening the sea voyage between Europe and Asia, eliminating weeks of travel time around Africa — quickly became apparent even to its former skeptics. In one of history's more striking reversals, Britain, having initially opposed the canal's construction, purchased Egypt's substantial shareholding in the Suez Canal Company in 1875 when the financially struggling Egyptian government (under Said Pasha's successor, Isma'il Pasha) sought to sell its shares, giving Britain a major ownership stake and significant influence over the canal's operation, which only grew following Britain's 1882 military occupation of Egypt, undertaken partly to protect this same strategic asset.
