Guerrero was born in Ybaroty, a neighbourhood in the city of
Villarrica del Espíritu Santo,
Paraguay. His parents were Vicente Ortiz and Susana Guerrero, who died after giving birth. He was raised by his grandmother, Florencia Ortiz. He completed his first studies in a school in Villarrica, and stood out for his interest in scholarly works. He was shy and not very social. While he was studying at the National College in Villarrica he wrote his first verses; during this time he acquired the "Manú" nickname. He arrived in
Asunción in 1914, where he studied in the
Colegio Nacional de la Capital. He published his first poems in the
Revista del Centro Estudiantil. Soon, local papers started to show interest in him. One of his most famous pieces, "Loca", was published in the magazine
Letras. He lived with his friend and also poet
Guillermo Molinas Rolón. In the 1920s he published poems such as "Surgente", "Pepitas" and "Nubes del este" and plays like "Eireté", "La Conquista" and "El crimen de Tintalila". He also wrote the lyrics in Guarani for some of his friend,
José Asunción Flores's songs. Pieces like "India" and "Buenos Aires" were written in Spanish. Guerrero was exiled from his country and went to
Brazil. He died in
Buenos Aires, Argentina, in 1933, due to
leprosy. His ashes rest in the city where he was born, and in a plaza of Asunción called "Manuel Ortiz Guerrero y José Asunción Flores". Posthumous publications of his works include
Obras completas (1952) and
Arenillas de mi tierra (1969). == Work ==
