The assassination of the Liberal leader Jorge Eliécer Gaitán in Bogotá on 9 April 1948 set off riots and then a decade of partisan killing in the Colombian countryside, in which Liberal and Conservative armed groups, police and army units destroyed villages, massacred families and drove opponents off their land. Deaths are conventionally estimated at around 200,000, within a published range of roughly 100,000 to 300,000, and about two million people were displaced, many permanently into the cities. Land seizure was a central mechanism rather than a by-product, concentrating coffee and cattle holdings. The violence was formally ended by the National Front power-sharing pact of 1958, but the self-defence groups and agrarian grievances it left behind fed directly into the guerrilla insurgencies from 1964 that the atlas already covers. Colombia's Centro Nacional de Memoria Histórica treats La Violencia as the opening phase of a continuous armed conflict.

Colombia's 1951 census (DANE) counted 11,548,172 inhabitants, of whom roughly 61 per cent, about seven million, lived in rural areas.
The commonly cited central figure is about 200,000. The range reflects the absence of any systematic registration during the period: estimates were built up after the fact from parish burial books, municipal records and regional studies, and differ over which years and which categories of killing to include.
The 1962 study by Guzmán, Fals Borda and Umaña Luna and subsequent reports of the Centro Nacional de Memoria Histórica document the village massacres, burnings, rapes and disappearances.
