All Fair In Love And War
Political disagreements can make for awkward dinner conversations today, but history took the idea of marrying across political lines to an entirely different level. Royal marriages regularly connected rival kingdoms, competing dynasties, opposing religious factions, and even families that had recently been fighting each other. Some of these women married men who represented a rival political camp, while others entered unions specifically designed to end a conflict. In several cases, the marriage worked beautifully; in others, it merely gave everyone a new reason to argue.
1. Emma of Normandy and Æthelred II
Emma of Normandy found herself at the center of a political struggle between England and Scandinavia when she married King Æthelred II in 1002. Emma married him as England and Normandy negotiated their political alliance. When the Danish conquest overturned English politics, Emma remarried the invader himself by becoming Queen of England and Denmark through Cnut.
2. Eleanor of Aquitaine and Henry II
Eleanor of Aquitaine’s second husband was an adversary of her first. After marrying King Louis VII of France and later divorcing him, Eleanor married Henry, Duke of Normandy and Count of Anjou, who would later ascend to the English throne as Henry II. Henry would become one of France’s greatest rivals during Eleanor’s lifetime.
3. Urraca of León and Alfonso I of Aragon
Queen Urraca of León and Castile married Alfonso I of Aragon in hopes of solidifying political connections between their realms. Their marriage was deeply unpopular with some nobles in Urraca’s territories who feared Alfonso’s influence. Once married, Urraca and Alfonso argued frequently, with their political disagreements even helping instigate a years-long civil war.

Elizabeth Woodville had family ties to England’s Lancaster royal house, while her husband Edward was from the York house that fought them in the Wars of the Roses.

7. Anne Neville and Richard III
Anne Neville's marriage to Richard, Duke of Gloucester, brought together two people whose families had fought on opposite sides of the Wars of the Roses. Anne had previously been married to Edward, Prince of Wales, the Lancastrian heir who passed away at the Battle of Tewkesbury. Richard, meanwhile, was one of the leading Yorkists responsible for defeating the Lancastrian cause. Their marriage therefore represented a remarkable reversal of political loyalties.

14. Maria Theresa of Spain and Louis XIV
Maria Theresa of Spain married Louis XIV of France as the two nations ended their own prolonged conflict. The Peace of the Pyrenees meant that Maria Theresa’s father, Philip IV of Spain, agreed to her marriage to Louis XIV as part of the settlement. It would help keep the peace between the two nations for a time, but Louis later invaded Spain using a claim connected to Maria Theresa’s ancestral lands.
