Later in 1794 (albeit during the subsequent year under the Republican Calendar in use at the time), Dordogne gained Parcoul from Charente-Inférieure. Following the restoration, in 1819, the commune of Bonrepos was suppressed and merged with the adjacent commune of Souillac in Lot. In 1870, shortly after France fought against Prussia in a war that the enemy was winning, a young aristocrat called Alain de Monéys was savagely tortured and then burned by a crowd of between 300 and 800 people for two hours on 16 August in a public square in the village of Hautefaye in the north-west of the department. Details of the incident remain unclear: the leading participants appear to have been drunk, and before the introduction of mass education most of the witnesses would have been unable (and possibly unwilling) to write down what they saw. But at some stage the victim died, and following a trial four individuals identified as culpable were in turn condemned to die by guillotine. The sentence was carried out in the same public square on 13 February 1885. It was suggested that the victim had reported the (bad) news of the war in a way that implied support for the enemy, although subsequently it became clear that his patriotic credentials were beyond reproach. It was also suggested that the mob had been antagonized when he called out, "Vive la République!" (Long live the republic) at a time when the patriotic villagers valued the imperial regime, which Parisian revolutionaries were in the process of destroying. This incident has been studied by historian Alain Corbin, among others. Geography The department is part of the region of Nouvelle-Aquitaine and is surrounded by the six départements of Haute-Vienne, Corrèze, Lot, Lot-et-Garonne, Gironde, Charente-Maritime, and Charente. Dordogne is the third-largest department of metropolitan France. It is slightly comparable in size to Cyprus or just under half the size of Slovenia. Principal towns The most populous commune is Périgueux, the prefecture. As of 2019, there are 9 communes with more than 5,000 inhabitants: Demographics The population peaked at 505,789 in 1851 according to that year's census. After that the population declined to 373,000 by 1975. This reflected the long term population decline observed in many of the rural departments resulting from changes in agriculture and the lure of higher industrial wages available in more urbanized regions. Between 1975 and 2010, the population increased again, reaching 415,000.
