In the spring of 1827, the ruler of Algiers struck a French diplomat with a fly-whisk during a heated argument over an unpaid debt. It was a gesture of contempt, but within three years, it was cited across France as the justification for a massive military expedition sent to seize a North African city. This episode explores how a diplomatic crisis over grain payments converged with the desperate domestic political needs of the French Bourbon monarchy to trigger an invasion.

The story of the 1830 expedition is not one of inevitable conquest. The French government calculated the political value of a successful campaign to win upcoming elections, but it entirely failed to plan for what would happen after victory. When the fleet sailed from Toulon, it captured the city of Algiers and seized a vast treasury, only for the government that launched the campaign to collapse in the July Revolution just weeks later. The new regime inherited an unplanned possession, and a series of short-term decisions made under pressure slowly hardened into a 132-year settler colony.

I wanted to understand how short-term political calculations can generate long-term historical consequences that escape the control of those who initiate them. Some questions sound simple until you try to answer them, and the origins of French Algeria reveal how an improvised military occupation, begun without a blueprint, can become a structural reality that shapes the lives of millions.
