crispi acquired the reputation of being the most aggressive and most impetuous member of his parliamentary group. he denounced the right for "diplomatising the revolution". personal ambition and restlessness made him difficult to cooperate with and he earned himself the nickname of "il solitario" (the loner). in 1864, he finally deserted mazzini and announced he was a monarchist, because as he put it in a letter to mazzini: "the monarchy unites us; the republic would divide us."
