Comandante Rolando Morán (December 29, 1929 – September 11, 1998) was the nom de guerre of Ricardo Arnoldo Ramírez de León, leader of Guatemalan National Revolutionary Unity (URNG), an armed Guatemalan resistance organization. At the time of his death he held the post of Secretary General of the URNG.
Born at Quetzaltenango in 1929, Ramírez studied law at the National University of San Carlos. At the end of the 1940s he became active as a counselor in the road construction trade union. He joined the Communist Party of Guatemala during the democratic period of the country (1944–54). It was in this time that he became acquainted with Che Guevara, who was touring the country. This was the beginning of a friendship of many years.
Ramírez began to fight Guatemala's rightist dictatorship after leftist president Jacobo Arbenz was overthrown by a U.S.-sponsored 1954 military coup. He was one of the organizers of the Guerrilla Army of the Poor in 1972, one of the four organizations which later formed the URNG. An unparalleled destruction campaign by the army under the 1982-83 presidency of General Efraín Ríos Montt, however, set an end for Ramírez's hopes for armed resistance against the government, and it became clear to him that the end of the armed conflict could be attained probably only by a negotiated solution.
Ramírez was involved in the peace process between the guerrillas and the government that restored democracy to Guatemala on December 29, 1996 and ended a 36-year-long civil war. After living many years in exile, President Álvaro Arzú allowed him to return to the country, and the URNG become a legal political party. Jointly with Arzú, he received the 1996 UNESCO Félix Houphouët-Boigny Peace Prize.
