The War That Lasted 335 Years But Had Zero Casualties

The War Everyone Forgot About

Imagine declaring war and then completely forgetting about it for over 300 years. That's exactly what happened between England and the tiny Isles of Scilly off the coast of Cornwall. In 1651, during the English Civil War, the Dutch declared war on these small islands. But here's the kicker – they never officially made peace!

The Most Peaceful War Ever

For 335 years, these two places were technically at war, but absolutely nothing happened. No battles, no casualties, no military action whatsoever. The islanders went about their daily lives fishing and farming, completely unaware they were supposedly at war. It wasn't until 1986 that a historian discovered this forgotten conflict and helped arrange an official peace treaty, finally ending the world's longest and most peaceful war.

The Forgotten Declaration

The Three Hundred and Thirty-Five Years' War began in 1651 during the chaos of the English Civil War. The Dutch Republic, supporting Parliament against the Royalists, declared war on the Isles of Scilly when the islands remained loyal to King Charles I. However, when the Royalist cause collapsed, everyone simply forgot about this tiny declaration.

Key Facts About This Peculiar Conflict

• Duration: 335 years (1651-1986) • Casualties: Exactly zero • Battles fought: None • Population of Scilly: About 2,000 people • Military action: Completely absent

The Peaceful Centuries

What makes this war remarkable is its complete lack of hostility. The Isles of Scilly continued their peaceful existence, with residents fishing, farming, and welcoming Dutch tourists who had no idea they were visiting "enemy territory." The Dutch government had no interest in actually fighting these remote islands, and the islanders were blissfully unaware of their official war status.

The Accidental Discovery

In 1985, historian Roy Duncan stumbled upon this forgotten conflict while researching local history. He contacted the Dutch Embassy, who confirmed that no peace treaty had ever been signed. The oversight was so amusing that both sides decided to make the peace ceremony a celebration, officially ending the war on April 17, 1986.

Historical Context and Origins

The Scilly Naval Disaster and subsequent declaration of war emerged from the complex political landscape of the English Civil War (1642-1651). The Isles of Scilly, strategically positioned in the Atlantic shipping lanes, became a Royalist stronghold under Sir John Grenville. Dutch Admiral Maarten Tromp declared war on behalf of the States General of the Netherlands in April 1651, primarily due to Royalist privateering activities that threatened Dutch commercial interests.

The Bureaucratic Oversight

When Parliamentary forces captured the islands in May 1651, the immediate cause of conflict disappeared. However, the Dutch States General never formally rescinded their declaration of war. This bureaucratic oversight occurred during the transition period when England and the Netherlands were negotiating broader peace settlements. The Treaty of Westminster (1654) ended the larger First Anglo-Dutch War but made no specific mention of the Scilly Islands.

Documentation and Legal Status

Archival research by Roy Duncan in 1985 revealed that while the Dutch declaration existed in the Nationaal Archief in The Hague, no corresponding peace treaty could be located. International law expert Professor Ian Brownlie confirmed that technically, a state of war could theoretically persist until formally resolved, though the Montevideo Convention criteria for statehood made the legal implications largely ceremonial.

The 1986 Peace Process

The resolution involved multiple stakeholders:

Modern Implications and Precedent

This case established important precedents for dormant conflict resolution and highlighted gaps in international treaty databases. The Peace Palace Library in The Hague now maintains enhanced records of minor territorial declarations to prevent similar oversights. The incident also demonstrated how micro-diplomacy between small territories can persist independently of larger geopolitical relationships, contributing to academic discourse on sub-national international relations and the persistence of historical legal frameworks in modern governance structures.
