The Thirteen Roses: Thirteen female members of the Unified Socialist Youth are executed by Francoist forces in Madrid, Spain.

"Las Trece Rosas" is the name given in Spain to a group of thirteen young women who were executed by a Francoist firing squad on 5 August 1939, just after the conclusion of the Spanish Civil War. Their execution was part of a massive execution campaign known as the "saca de agosto", which included 43 young men.

The Unified Socialist Youth was a youth organization formed in the spring of 1936 in Spain through the amalgamation of the Spanish Socialist Workers' Party (PSOE) and Communist Party of Spain (PCE) youth groups. Its leader, Santiago Carrillo, came from the Socialist youth, but had secretly joined the Communist youth prior to the merger, and the group was soon dominated by the PCE.

Francoist Spain, also known as the Francoist dictatorship, or Nationalist Spain was the period of Spanish history between 1936 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title Caudillo. After his death in 1975, Spain transitioned into a democracy. During Franco's rule, Spain was officially known as the Spanish State. The informal term "Fascist Spain" is also used, especially before and during World War II.
