Don Camillo [ˈdɔŋ kaˈmillo] is a character created by the Italian writer and journalist Giovannino Guareschi, based on an actual Roman Catholic priest, World War II partisan and detainee at the concentration camps of Dachau and Mauthausen, named Don Camillo Valota (1912-1998). The fictional Don Camillo is one of two main protagonists of Guareschi's short stories, the other being the communist mayor of the town, Peppone. The stories are set in what Guareschi refers to as the "small world" of rural Italy after World War II.
Most of the Don Camillo stories came out in the weekly magazine Candido, founded by Guareschi with Giovanni Mosca. These "Little World" (Italian: Mondo piccolo) stories amounted to 347 in total and were put together and published in eight books, only the first three of which were published when Guareschi was still alive.
In the post-war years (after 1945), Don Camillo Tarocci (his full name, which he rarely uses) is the hotheaded priest of a small town in the Po valley in northern Italy. Don Camillo is a big man, tall and strong with hard fists. For the films, the town chosen to represent that of the books was Brescello (which currently has a museum dedicated to Don Camillo and Peppone) after the production of movies based on Guareschi's tales, but in the first story Don Camillo is introduced as the parish priest of Ponteratto.
Don Camillo is constantly at odds with the communist mayor, Giuseppe Bottazzi, better known as Peppone (meaning, roughly, Big Joe) and is also on very close terms with the crucifix in his town church. Through the crucifix he hears the voice of Christ. The Christ in the crucifix often has far greater understanding than Don Camillo of the troubles of the people, and has to constantly but gently reprimand the priest for his impatience.
What Peppone and Camillo have in common is an interest in the well-being of the town. They also appear to have both been partisan fighters during World War II; and while Peppone makes public speeches about how "the reactionaries" ought to be shot, and Don Camillo preaches fire and brimstone against "godless Communists", they actually grudgingly admire each other. Therefore, they sometimes end up working together in peculiar circumstances, though keeping up their squabbling. Thus, although he publicly opposes the Church as a Party duty, Peppone takes his gang to the church and baptises his children there, which makes him part of Don Camillo's flock. Don Camillo also never condemns Peppone himself, but the ideology of communism which is in direct opposition to the church.
