The Contras were a collection of freedom fighters and political activists opposed to communism in Nicaragua in the 1980s. They were dubbed "counter-revolutionaries" by the leftist Sandinista government of Nicaragua in the 1980s. The United States under Presidents Jimmy Carter  and Ronald Reagan covertly supported the Contras.
Revelations of this covert funding fueled the Iran-Contra affair. Oliver North, who was intimately involved with the funding, is currently a senior correspondent at the Fox News Channel. No one was ever convicted of violating any law by funding the Contras. Convictions for other aspects of the covert operation were overturned on appeal.
Leftist propaganda portrayed them as even more notorious brutes than the Sandinistas. According to this portrayal, the Contras "regularly destroyed health centers, schools, agricultural cooperatives, and community centers-symbols of the Sandinistas' social programs in rural areas." 
President Ronald Reagan honored the Contras by describing them as the "Moral Equivalent of our Founding Fathers."
Over the course of the war, nearly 30,000 Nicaraguans were killed by the Contras, with many more wounded.
