The United States occupation of Veracruz began with the Battle of Veracruz and lasted for seven months. The incident came in the midst of poor diplomatic relations between Mexico and the United States, and was related to the ongoing Mexican Revolution.

Mexico and the United States have a complex history, with war in the 1840s and the subsequent American acquisition of more than 50% of former Mexican territory, including Texas, California, and New Mexico. Pressure from Washington forced the French invaders out in the 1860s. The Mexican Revolution of the 1910s saw many refugees flee North, and limited American invasions. Other tensions resulted from seizure of American mining and oil interests. The two nations share a maritime and land border. Several treaties have been concluded between the two nations bilaterally, such as the Gadsden Purchase, and multilaterally, such as the 2019 United States–Mexico–Canada Agreement, replacing the 1994 NAFTA. Both are members of various international organizations, including the Organization of American States and the United Nations.
