Which is the shortest and longest war in history?

The Anglo-Zanzibar was fought between the United Kingdom and Zanzibar on August 27, 1986. With duration of only 45 minutes, it holds the record of being the shortest war. The Three Hundred and Thirty Five Years war (1651-1986) was between the Netherlands and the Isles of Scilly (off the south-west coast of the United Kingdom). It is said to have been extended by the lack of a peace treaty for 335 years. It was waged without a single shot fired, making it one of the world’s longest wars and the war with the fewest casualties. Despite the uncertain validity of the declaration of war, peace was finally declared in 1986.
