The origin of Nicaraguan literature can arguably be traced to pre-Columbian times. The myths and oral literature formed the cosmogenic view of the world of the indigenous people. Some of these stories are still known in Nicaragua. Like many Latin American countries, the Spanish conquerors have had the most effect on both the culture and the literature. Nicaraguan literature has historically been an important source of poetry in the Spanish-speaking world, with internationally renowned contributors such as Rubén Darío who is regarded as the most important literary figure in Nicaragua. He is called the "Father of Modernism" for leading the ''modernismo'' literary movement at the end of the 19th century. Other literary figures include Carlos Martinez Rivas, Pablo Antonio Cuadra, Alberto Cuadra Mejia, Manolo Cuadra, Pablo Alberto Cuadra Arguello, Orlando Cuadra Downing, Alfredo Alegría Rosales, Sergio Ramirez Mercado, Ernesto Cardenal, Gioconda Belli, Claribel Alegría and José Coronel Urtecho, among others.
