The Right was opposed by the more progressive Historical Left, which overthrew Marco Minghetti's government during the so-called "Parliamentary Revolution" of 1876, which brought Agostino Depretis to become Prime Minister. However, Depretis immediately began to look for support among Rightists MPs, who readily changed their positions, in a context of widespread corruption. This phenomenon, known in Italian as "trasformismo" (roughly translatable in English as "transformism"—in a satirical newspaper, the PM was depicted as a chameleon), effectively removed political differences in Parliament, which was dominated by an undistinguished liberal bloc with a landslide majority until World War I.
