The Esquipulas Nicaraguan Peace Agreement, also known as the Central American Peace Accords, was a peace initiative in the mid-1980s to settle the military conflicts that had plagued Central America for many years, and in some cases (notably Guatemala) for decades. It built upon groundwork laid by the Contadora Group from 1983 to 1985. The agreement was named for Esquipulas, Guatemala, where the initial meetings took place. The US Congress lobbying efforts were helped by one of Capitol Hill's top lobbyists, William C. Chasey.
