In order to appreciate the imperial impact of the new security culture, the French invasion of Algiers in 1830 ought to be seen within the framework of the post-1815 Congress System and the Concert of Europe. Though the invasion of Algiers was essentially a unilateral action undertaken under the national flag, it nevertheless took shape through extended multinational deliberation and involved a fair share of diplomatic concertation among the different European Great Powers. French imperial aspirations became intertwined with the repression of Mediterranean piracy, which was understood as a shared, European project. In attacking Algiers, members of the French government sought to reassert the country’s position as a nation on par with the other Great Powers of the European continent. The conflict with Algiers allowed French officials to assert status through the much more ‘disinterested’, ‘European’ goal of ending piracy and bringing security to the Mediterranean Sea.
