Historical Context of Royal Cousin Marriages
Royal cousin marriages were common across Europe to keep wealth and power within a limited gene pool. These unions aimed to prevent external influence and solidify political bonds between nations.
By the early twentieth century, many reigning families were interconnected through a relatively small group of ancestors, making cousin unions almost inevitable for dynastic stability.
Genetic and Legal Implications
Biologically, third cousins share a modest percentage of DNA, and while health risks are generally low, such marriages still raise ethical considerations regarding genetic diversity. Legally, many jurisdictions regulate degrees of consanguinity in marriage to mitigate inherited disorders.
The union of Elizabeth and Philip prompted thorough review under the Royal Marriages Act 1772, which required explicit consent from the monarch for descendants of George II to marry.
