The years from 1971 to 1975 are known as the "Quinquenio Gris" (roughly "Five-year Grey Period"). The National Congress of Education and Culture, held from April 23 to April 30 in 1971, set out to establish a policy to abolish the inquisitive and questioning role of literature, which bore negative consequences for the short story writing of those times. Despite that, works published during the five-year period include "El fin del caos llega quietamente" (1971) by Ángel Arango, "Onoloria" (1973) by Miguel Collazo, "Los testigos" (1973) by Joel James and "Caballito blanco" (1974) by Onelio Jorge Cardoso.
