Carlo Pisacane, Italian soldier and philosopher (b. 1818)
Carlo Pisacane, Duke of San Giovanni (22 August 1818 – 2 July 1857) was an Italian patriot and one of the first Italian socialist thinkers. He argued that violence was necessary not only to draw attention to, or generate publicity for, a cause, but also to inform, educate, and ultimately rally the masses behind the revolution. These ideas are called propaganda of the deed and have exerted compelling influence on rebels and terrorists alike ever since.
