It should be the war between Britain and France (1337- 1453), which lasted intermittently for 1 16 years.
The reason is that Britain and France compete for Flanders.
The last hundred years' war ended in the victory of France. The closing mark is 1453 10, and the British troops in Bordeaux surrender. So far, all French territories except Calais have recovered their own territories.
The shortest war
The British war against Zanzibar (1August 27th, 896) lasted only 45 minutes, making it the shortest war in history. Before the war broke out, Sultan Hamad bin Duvini of Zanzibar volunteered to be a puppet under British colonial rule. 1896 On August 25th, Hamad bin Doignies died, and his nephew Khalid bin Bagash staged a military coup and established himself as Sudan. The British supported another candidate, Mahmoud Benmohamed, to cooperate with his colonial rule. Therefore, Britain issued an ultimatum and ordered Bagash to abdicate. Bagash refused to abdicate and organized troops to defend the palace. The Royal Navy sent five warships to surround the port in front of the palace, and at the same time sent the Royal Marine Corps to land to support the Zanzibar regular army loyal to Britain. Sultan Bagash contacted the American representative on the island and asked the United States to mediate in an attempt to negotiate peace with Britain as a last resort, but the United States refused. 1896 at 9: 00 a.m. on August 27th, as soon as the ultimatum time passed, the Royal Navy Fleet fired immediately. Gunfire rumbled, the palace collapsed, and Zanzibar's army suffered heavy casualties. Bagash hurriedly hid in the German consulate and was granted asylum. After 45 minutes, the British ceased fire and ordered the Germans to hand over the deported Sudan. However, Bagash escaped from the sea at 1896 10.02. Since then, he has been in exile in Dar es Salaam until he was captured by the British army in 19 16. After his arrest, Bagash was allowed to live in Mombasa, Kenya until his death in 1927. After the war, the British government asked the Zanzibar government to compensate the British army for its arms expenses in the war.
