Pilar Millán Astray was born in 1879 during the Restauración, the Spanish equivalent of the Victorian period, in a family that belonged to the bourgeoisie of conservative La Coruña in the province of Galicia.

She was the most performed playwright in Madrid during the 1923–1924 season, with more than one hundred performances. In 1926, critics declared her one of the three most popular playwrights, besides Muñoz Seca and Carlos Arniches. Her most
