United_States_occupation_of_Veracruz--Franz_Von_Papen

The United States occupation of Veracruz (April 21 to November 23, 1914) 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.
The occupation was a response to the Tampico Affair of April 9, 1914, where Mexican forces had detained nine American sailors. The occupation further worsened relations, and led to widespread anti-Americanism in Mexico.
