In Spain, a Semana Negra ("black week") is a literary festival that celebrates crime fiction and detective stories with a variety of events for literature, cinema, theater, photography and gastronomy.
The term "black week" refers to how the week-long festivals focus on the genre of literature that deals with "darker" subject matters.
[1] After the first year, the festival expanded to include cities like Zaragoza, Huesca, Calatayud, Pina de Ebro, and Valderrobres.
[5] The bookseller Paco Camarasa, founder and owner of the Black and Criminal Bookstore of Barcelona, started the festival in 2005, taking advantage of the fact that the Barcelona City Council was celebrating the Year of the Book and dedicated several events to the memory of the Spanish novelist Manuel Vázquez Montalbán.
These meetings were a success with the public, encouraging the bookseller to propose an annual festival dedicated to the noir genre.
