A Name for Queens
By the late Middle Ages, Catherine had become one of the most common royal names in Europe. Catherine of Aragon, the Spanish princess who married Henry VIII in 1509, became one of the most consequential figures in English history when her refusal to accept an annulment set off a political and religious crisis that would reshape the country.
Two centuries later, Catherine the Great (Catherine II) ruled Russia from 1762 to 1796, expanding the empire's borders, modernizing its legal code, and building one of the world's great art collections at the Hermitage in Saint Petersburg.
