The Franco-Mexican War, which occurred from 1861 to 1867, involved significant military engagements between French forces, Mexican conservatives, and Mexican liberals. Estimates of the total number of casualties are varied, but it is believed that approximately 50,000 to 100,000 lives were lost due to the conflict.
This staggering number includes soldiers from both the French and Mexican sides, as well as civilian casualties resulting from the war’s impact on the population. The exact figures are difficult to determine, as the records from that time were not always accurate or comprehensive.
The war ultimately ended with the expulsion of French troops and the reestablishment of a republican government in Mexico, but it left deep scars on the nation and its people, contributing to the broader socio-political struggles that continued for years after the conflict.
