Franco-Mexican War
The second French intervention in Mexico, also known as the Maximilian Affair or the Franco-Mexican War was an invasion of Mexico in late 1861 by the Second French Empire, supported in the beginning by the United Kingdom and Spain. It followed President Benito Juárez's suspension of interest payments to foreign countries on 17 July 1861, which angered these three major creditors of Mexico. Initially, the three European powers signed the Treaty of London to unite their efforts but when the British and Spanish discovered that France planned to seize all of Mexico, they quickly withdrew from the coalition. The subsequent French invasion resulted in the Second Mexican Empire but after heavy guerrilla resistance led by Juárez, which continued even after the capital had fallen in 1863, the French eventually withdrew from Mexico and Maximilian I was executed in 1867.
