In 1876, Franchetti travelled to Sicily with
Sidney Sonnino to conduct an unofficial inquiry into the state of Sicilian society. In 1877, the two men published their research on
Sicily in a substantial two-part report. In the first part Sonnino analysed the lives of the island's landless peasants. Franchetti's half of the report,
Political and Administrative Conditions in Sicily, was an analysis of
the Mafia in the nineteenth century that is still considered authoritative today. Franchetti would ultimately influence thinking about the Mafia more than anyone else until
Giovanni Falcone over a hundred years later.
Political and Administrative Conditions in Sicily is the first convincing explanation of how the Mafia came to be. Franchetti saw the Mafia as an "industry of violence" and described the designation of the term "Mafia": "the term mafia found a class of violent criminals ready and waiting for a name to define them, and, given their special character and importance in Sicilian society, they had the right to a different name from that defining vulgar criminals in other countries". He saw the Mafia as deeply rooted in Sicilian society and impossible to quench unless the very structure of the island's social institutions were to undergo a fundamental change. The Franchetti-Sonnino report was rebuked and labelled as 'unpatriotic'. It is now considered one of the most coherent and comprehensive accounts of the Sicilian mafia and its surroundings. ==In Eritrea==
