1867 in Mexico

In 1867, the Second Mexican Empire collapsed, marking the consolidation of the Mexican Republic and the victory of the Liberal government. Emperor Maximilian I, after losing the support of the French army and failing to secure sufficient military backing within Mexico, remained in power until he was captured at Querétaro along with his leading generals. He was subsequently tried and sentenced to death despite international appeals for clemency.

The defeat of the Imperial forces was carried out by Liberal commanders including Porfirio Díaz, who captured Puebla, and Mariano Escobedo, who took Querétaro. On 15 July 1867, constitutional president Benito Juárez returned to Mexico City, bringing the Second French Intervention to an end.
