When examining the question of what is the longest civil war in history, most modern observers immediately think of recent conflicts in the Middle East or Africa. However, the true record holder stretches back centuries, originating in the highlands of Scotland and evolving through distinct phases that mirror the political and religious upheavals of the British Isles. This protracted struggle, often overshadowed by the more dramatic battles of the English Civil War, represents a continuous thread of resistance and governance that persisted well into the 18th century.
The Jacobite Risings: A Multi-Century Conflict
To identify the longest civil war, one must look beyond the American Revolution or the Spanish Civil War to the series of conflicts known as the Jacobite Risings. While these are frequently remembered as romantic rebellions marked by tartan and tragic last stands, they were part of a sustained political and military campaign lasting over 150 years. The core issue was the succession to the English, Scottish, and later British throne, pitting the supporters of the exiled Stuart dynasty against the reigning Houses of Orange and Hanover.
Defining the Timeline
The conflict effectively began with the Glorious Revolution of 1688, when James II was deposed. The first major armed confrontation, the Jacobite rising of 1689, kicked off a series of organized military campaigns. The final chapter concluded with the defeat at Culloden in 1746 and the subsequent suppression of Highland culture. This places the active military phase of this civil conflict squarely within the 17th and 18th centuries, a timeline that predates the formation of the United States by nearly a century.
Conflict | Start Year | End Year | Duration
Jacobite Risings (Key Phase) | 1689 | 1746 | 57 years
American Civil War | 1861 | 1865 | 4 years
Chinese Civil War (Main Phase) | 1927 | 1950 | 23 years
Global Contenders and the Definition of "Civil"
While the Jacobite timeline is significant, the title of longest civil war is frequently contested by other global conflicts. The American Civil War, despite its immense global impact, lasted only four years. Similarly, the Chinese Civil War, which shaped the modern geopolitical landscape of East Asia, spanned roughly 23 years between its major phases. These durations, however, pale in comparison to the sheer longevity of the various conflicts that erupted after the collapse of the Qing Dynasty, some of which technically continue to this day in various forms, pushing the duration into the exceeding century.
The Troubles in Northern Ireland
Another prominent candidate for the longest continuous civil conflict in the modern era is The Troubles. Spanning approximately 30 years from the late 1960s to the Good Friday Agreement in 1998, this period was marked by intense sectarian violence between Irish nationalists and British unionists. Although the intensity fluctuated and the death toll was significantly lower than other civil wars, the sustained political tension and periodic outbreaks of violence over three decades represent a distinct model of prolonged internal strife.
