Guiseppe Mazzini: He was an Italian revolutionary who played a significant role in promoting the idea of a unified Italian state. He believed that nations were the natural units of mankind, and so Italy (which was then divided into a number of small states and kingdoms) had to be forged into a single unified republic. During the 1830s, he strived to put together a coherent programme for such a unitary Italian Republic. He also set up two secret societies, namely Young Italy and Young Europe. These societies helped in the dissemination of his ideas.
