Cork’s history of rebellion can be traced back at least as far as the 9th-century arrival of the Vikings; the Fragmentary Annals of Ireland documented that people from what are now the counties of Waterford and Cork destroyed a Viking castle and killed the Norse leader known as Gnimbeolu.
Later, during the 12th century, Cork’s ambitious MacCarthy clan managed to briefly wrestle control over the southern part of the then-Kingdom of Munster from the O’Brien family, turning Cork and Kerry into a separate kingdom, the Kingdom of Desmond.
After the Norman invasion, the MacCarthys were superseded by the FitzGerald dynasty – a Hiberno-Norman family famously referred to as being ‘more Irish than the Irish themselves’, for their readiness to embrace Gaelic culture.
It was a descendent of this family, Gerald FitzGerald, 8th Earl of Kildare – known as the unofficial King of Ireland – who set events in motion during the 15th century that would ultimately earn Cork the nickname ‘the rebel county’.
After Henry VII won the Wars of the Roses and seized the English crown in 1485, FitzGerald openly supported the claim of the supposed young Earl of Warwick – later found to be a Yorkist imposter named Lambert Simnel – to the throne and the Lordship of Ireland.
A rebellion against Henry VII was launched from Ireland and ultimately quashed, but in 1491, yet another pretender to the English throne – a man named Perkin Warbeck, claiming to be the Duke of York – arrived in Cork City. Though the Earl of Kildare stayed out of this second attempt to steal the crown, the majority of the people of Cork – including the Lord Mayor – stood behind Warbeck. It is because of this apparent support of Warbeck that Cork became known to the English monarchy as ‘the rebel county’.
Though the name originated during these specific early Tudor uprisings, Cork was to be the site of plenty more revolts throughout the centuries to come. The FitzGeralds went on to launch the Desmond Rebellions – two unsuccessful periods of intense struggle that took place throughout the late 1500s, against increasing assertions of control over Ireland by England.
In 1601, England’s victory at the Battle of Kinsale in County Cork put an end to this period of Irish insurrection, nearly annihilating Gaelic Ireland. But Cork’s part in the rebellion still wasn’t over. During in the 20th century, the county became a focal point of Irish nationalism once again, playing a significant role in the Irish War of Independence.
