 Since he wanted to remain in Switzerland, Rousseau decided to accept an offer to move to a tiny island, the Ile de St.-Pierre, having a solitary house.Although it was within the Canton of Bern, from where he had been expelled two years previously, he was informally assured that he could move into this island house without fear of arrest, and he did so (10 September 1765).However, on 17 October 1765, the Senate of Bern ordered Rousseau to leave the island and all Bernese territory within fifteen days.
