The Kingdom of Newfoundland is a close ally of the North American Federation. Its head of state is King William V through his Viceroy. The Kingdom of Newfoundland voted on joining the Federation in the early 1960's, but the measure was narrowly defeated. The Kingdom generally tends to keep to itself. In the early 1980s, the Kingdom enacted laws restricting access to the fishing grounds in order to preserve the fish stock for later generations. Through its mainland territory of Labrador, the Kingdom also produced much hydroelectric energy, much of which is sold to Canada and Quebec.
