At first, these French immigrants from the rural areas of Poitou-Charentes settled in what is now eastern Canada, and established an agricultural and maritime economy (farming and fishing). This area of the "New World" was dubbed "Acadia" by the French, after the Greek "Arcadia" - the idyllic part of the Peloponnesian peninsula in Greece. As an alternate theory, some historians suggest that the name is derived from the indigenous Canadian Mikmaq language, in which Cadie means "fertile land". It was renamed "Nova Scotia" (New Scotland) in the aftermath of the 1755 expulsion of most of the Acadians by the English.
