Political map of Europe & the Mediterranean 14 June 1830 (French invasion of Algeria): Following three years of deteriorating relations, France invaded Algiers in mid-1830 (Invasion of Algiers in 1830). Although their swift victory would initiate over a century of French rule in the region (French Algeria), it would be many more decades before the country was fully pacified. The success also failed to save the unpopular French King (Charles X of France), who was forced to abdicate when Paris broke into revolution (July Revolution) just weeks later.
