An 85-year-old doctor will appear in a Madrid court Tuesday, the first person to stand trial over an alleged practice that saw thousands of babies stolen under Spain’s military dictatorship during the mid-twentieth century. Known as the lost children of the Franco-era, as many as 300,000 babies are estimated to have been abducted from their mothers under General Francisco Franco, who ruled Spain from 1939-75, and in the decades after. The theft of newborns began in the 1930’s after the Spanish Civil War as an ideological practice, stripping left-wing parents or Franco-opponents of their children as a way of ridding Marxist influence from society.
