In spite of growing up in a conservative family, Dulce Chacón soon became a leftist, due to the victims caused by the Spanish dictatorship.
Chacón started writing at an early age even though she did not publish until 1992 when her first book of poetry, Querrán ponerle nombre, appeared.
Her novel La voz dormida (The sleeping voice), which gathers testimonies of women who took part in the republican side during the Spanish Civil War, attracted widespread acclaim.
There she went along to read aloud, alongside Nobel prize winner José Saramago, the anti-war manifesto at the 15 March 2003 mass demonstration in Madrid against the war.
Her husband, Miguel Ángel Alcántara, would define her as a determined, leftist, agnostic woman, whose best weapons were words and writing.
