Credere - Obbedire - Combattere" or "To believe - To obey - To fight".
The play "Credere - Obbedire - Combattere" was written by sisters Clara and Laura Masilotti (of Italian nationality) in the late 1950s or early 1960s.
The story belongs to the genre of alternative history, where the Italian anarchist Caserio assassinates the Emperor of France, Napoleon IV instead of the Italian Prime Minister Francesco Crispi.
This action led to the rise of European tensions, which only worsened when in 1895 Crispi sent the Italian fleet west against France and east against the Ottoman Empire (for Albania) and Russia (a threat to Italy).
Resulting in the great European war between France, Russia, Austria-Hungary, the Ottoman Empire and the United Kingdom against Germany, Italy, Romania, among many other secondary and minor powers within the conflict.
"Credere - Obbedire - Combattere" explores a world of an Italy still strongly motivated by Francesco Crispi, marked by authoritarianism, nationalism, imperialism and racism along conservative lines.
The Masilotti sisters' interest in alternate history is believed to be based on their search for a treasure in Latin America (Uruguay), supposedly left during Garibaldi's stay in Uruguay due to an Italian cardinal or sent to Uruguay by José María Mastai (better known as Pope Pius IX), possible grandfather of the Masilotti sisters.
