What was the longest war in world history?

There was a theoretical state of war that existed between the Isles of Scilly and the Netherlands for 335 years, from March 30, 1651 to April 17, 1986, and is considered the longest war in the history of world. Although there is still no clear data available that can confirm the existence of this war, it has been popular as the longest bloodless war.

The "Three Hundred and Thirty Five Years' War" could have ended a long time ago, if a peace treaty was made. There was not even a single shot fired, and both sides declared peace, in 1986, at the request of Roy Duncan, the Chairman of the Isles of Scilly Council and a historian.
