The 1958 Lebanon crisis was a political crisis in Lebanon caused by political and religious tensions in the country that included a United States military intervention. The intervention lasted for around three months until President Camille Chamoun, who had requested the assistance, completed his term as president of Lebanon. American and Lebanese government forces successfully occupied the Port of Beirut and Beirut International Airport. With the crisis over, the United States withdrew.
