The Mexican campaign, 1862-1867

Following years of political instability and a financial crisis that had crippled the country, the president of Mexico, Benito Juárez, announced a suspension on all repayment on loans contracted with European powers. This declaration set in motion a wave of consternation and indignation that swept through Britain, France, and Spain, resulting in a suspension of diplomatic relations and the decision to launch a tripartite military expedition to Mexico.
