in 1871. From 1848 until independence, France administered the whole Mediterranean region of Algeria as an integral part and département of the nation. One of France's longest-held overseas territories, Algeria became a destination for hundreds of thousands of European immigrants, who became known as colons and later, as Pied-Noirs. Between 1825 and 1847, 50,000 French people emigrated to Algeria. These settlers benefited from the French government's confiscation of communal land from tribal peoples, and the application of modern agricultural techniques that increased the amount of arable land. Many Europeans settled in Oran and Algiers, and by the early 20th century they formed a majority of the population in both cities. During the late 19th and early 20th century, the European share was almost a fifth of the population. The French government aimed at making Algeria an assimilated part of France, and this included substantial educational investments especially after 1900. The indigenous cultural and religious resistance heavily opposed this tendency, but in contrast to the other colonized countries' path in central Asia and Caucasus, Algeria kept its individual skills and a relatively human-capital intensive agriculture. During the Second World War, Algeria came under Vichy control before being liberated by the Allies in Operation Torch, which saw the first large-scale deployment of American troops in the North African campaign. Gradually, dissatisfaction among the Muslim population, which lacked political and economic status under the colonial system, gave rise to demands for greater political autonomy and eventually independence from France. In May 1945, the uprising against the occupying French forces was suppressed through what is now known as the Sétif and Guelma massacre. Tensions between the two population groups came to a head in 1954, when the first violent events of what was later called the Algerian War began after the publication of the Declaration of 1 November 1954. Historians have estimated that between 30,000 and 150,000 Harkis and their dependents were killed by the National Liberation Front (FLN) or by lynch mobs in Algeria. The FLN used hit and run attacks in Algeria and France as part of its war, and the French conducted severe reprisals. In addition, the French destroyed over 8,000 villages and relocated over 2 million Algerians to concentration camps. The war led to the death of hundreds of thousands of Algerians and hundreds of thousands of injuries. Historians, like Alistair Horne and Raymond Aron, state that the actual number
