The Plan de Snchez massacre took place in the Guatemalan village of Plan de Snchez, Baja Verapaz department, on 18 July 1982. Over 250 people (mostly women and children, and almost exclusively ethnic Achi Maya) were abused and murdered by members of the armed forces and their paramilitary allies.

The killings took place during one of the most violent phases of Guatemala's Civil War, which pitted various groups of left-wing insurgents against the government and the armed forces. After assuming power in March 1982, de facto President Gen. Efran Ros Montt embarked on a military campaign that largely succeeded in breaking the insurgency, but at a terrible cost in human lives and human rights violations. The massacre in Plan de Snchez was an element in the government's scorched earth strategy, and the village was targeted because of the authorities' suspicions that the inhabitants were harbouring or otherwise supporting guerrilla groups.

After the massacre, the village was practically abandoned for a number of years, and the survivors were told that reprisals would follow if they spoke about the incident or revealed the location of the numerous mass graves they had helped to dig. With the gradual return to democracy that began in the late 1980s and early 1990s, some of the survivors felt they could start to talk about the killings without fearing for their lives. Accusations were filed with the authorities in 1992 and, in 1993, a criminal investigation was launched. However, faced with delays and other irregularities in the proceedings, and stonewalled by a National Reconciliation Law that granted amnesties to the suspected perpetrators, the survivors saw that Guatemala's domestic legal remedies were ineffective in this case. They consequently decided to lodge a complaint with the Inter-American Commission on Human Rights (IACHR), the supranational human rights arm of the Organisation of American States, in 1996.

The IACHR began processing the complaint, received a partial recognition of the state's institutional responsibility from the democratically elected president Alfonso Portillo in the first year of his term, and finally referred the case to the Inter-American Court of Human Rights for judgement and settlement. In 2004, the Inter-American Court issued two judgements, in which it established Guatemala's liability in the case and ordered an extensive package of monetary, non-monetary and symbolic forms of compensation for the survivors and the next-of-kin of the deceased.

Guatemala ( (listen) GWAH-tə-MAH-lə; Spanish: [ɡwateˈmala] (listen)), officially the Republic of Guatemala (Spanish: República de Guatemala), is a country in Central America, bordered by Mexico to the north and west, Belize and the Caribbean to the northeast, Honduras to the east, El Salvador to the southeast and the Pacific Ocean to the south. With an estimated population of around 17.2 million, it is the most populous country in Central America and is the 11th most populous country in the Americas. Guatemala is a representative democracy; its capital and largest city is Nueva Guatemala de la Asunción, also known as Guatemala City, the largest city in Central America.

The core of the Maya civilization, which extended across Mesoamerica, was historically based in the territory of modern Guatemala. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823 Guatemala became part of the Federal Republic of Central America, which dissolved by 1841.

From the mid- to late 19th century, Guatemala suffered chronic instability and civil strife. Beginning in the early 20th century, it was ruled by a series of dictators backed by the United Fruit Company and the United States government. In 1944, the authoritarian leader Jorge Ubico was overthrown by a pro-democratic military coup, initiating a decade-long revolution that led to sweeping social and economic reforms. A U.S.-backed military coup in 1954 ended the revolution and installed a dictatorship.From 1960 to 1996, Guatemala endured a bloody civil war fought between the US-backed government and leftist rebels, including genocidal massacres of the Maya population perpetrated by the military. Since a United Nations–negotiated peace accord, Guatemala has achieved both economic growth and successful democratic elections, although it continues to struggle with high rates of poverty and crime, drug cartels, and instability. As of 2014, Guatemala ranks 31st of 33 Latin American and Caribbean countries in terms of the Human Development Index.Guatemala's abundance of biologically significant and unique ecosystems includes many endemic species and contributes to Mesoamerica's designation as a biodiversity hotspot.
