On 17 April 1986 a remarkable event occurred in the Isles of Scilly – something overlooked by history books and the Guinness Book Of World Records – the longest war in history was ended.
War was declared in 1651.
In 1985, local historian-come-Chairman of the Council, Roy Duncan, decided to look into the rumours that “Scilly was still at war with the Netherlands”. When he asked the Dutch embassy in London, they said that the rumour was accurate. Cllr. Duncan decided to invite the Dutch ambassador in London, Jonkheer Huydecoper, to the Islands in order to sign they treaty.
The treaty was signed on 17 April 1986, 335 years after it was declared.
