When did the french withdrew troops from mexico what encouraged them to do so?

The French withdrew their troops from Mexico in 1867. The withdrawal was largely influenced by several factors, including increasing pressure from the United States and internal issues in France. The presence of French troops in Mexico was part of the larger context of the French intervention in Mexico (1861-1867).

One of the key factors that encouraged the French withdrawal was the change in the political situation in France. In 1867, Emperor Napoleon III faced mounting challenges and political instability at home. The French intervention in Mexico was costly and unpopular, and the French government was under pressure to redirect resources and attention to domestic concerns.

Additionally, the United States, under President Andrew Johnson, opposed the French intervention in Mexico and had been supplying diplomatic and logistical support to the Mexican resistance, led in part by figures like Benito Juárez. As the American Civil War concluded, the U.S. government became more assertive in its opposition to foreign intervention in the Americas under the Monroe Doctrine. This increased pressure from the United States further contributed to the French decision to withdraw.

In 1867, faced with domestic issues and international pressure, the French began to withdraw their troops from Mexico. This eventually led to the fall of the French-backed regime in Mexico and the restoration of the Mexican Republic under Benito Juárez.
