By the 1950s, Venezuelan media led grassroots movements demanding the acquisition of Guayana Esequiba. Under the dictatorship of Marcos Pérez Jiménez, the Venezuelan government began plans to invade Guayana Esequiba. President Pérez Jiménez anticipated the invasion of Guyana in 1958, but was ultimately overthrown in the 1958 Venezuelan coup d'état before this was finalized.
