|An ongoing revolution against the government of Anastasio Somoza came to an end when Somoza fled the country. Somoza was forced out when the middle class deserted him after the assassination of newspaper editor Pedro Joaquin Chamorro. The U.S. cut off all aid for the Somoza regime, and eventually the 43-year Somoza dynasty in Nicaragua came to an end. Taking power in its stead were the Sandinistas, who were pro-Communist and received support from Cuba's Castro and the Soviet Union. This antagonized the U.S, and led to American support for the Contras, who opposed the new Nicaraguan government.
