An alleged state of war lasting 335 years between the Netherlands and the Isles of Scilly declared peace bringing an end to any hypothetical war that may have been legally considered to exist.

The Three Hundred and Thirty Five Years' War was an alleged state of war between the Netherlands and the Isles of Scilly. It is said to have been extended by the lack of a peace treaty for 335 years without a single shot being fired, which would make it one of the world's longest wars, and a bloodless war. Despite the uncertain validity of the declaration of war, and thus uncertainty about whether or not a state of war ever actually existed, peace was finally declared in 1986, bringing an end to any hypothetical war that may have been legally considered to exist.
