Maria of Jülich-Berg was a noblewoman born in 1450 in the region of Jülich-Berg, which is now part of modern-day Germany. She was the daughter of William IV, Duke of Jülich-Berg and Maria of Cleves. Maria played a significant role in the political landscape of her time through her marriage alliances. In 1475, Maria married John I of Cleves, which strengthened the ties between their families. This union was part of a broader strategy to consolidate power among the noble houses in the Holy Roman Empire. Maria's lineage and connections contributed to the political dynamics of the region during the late 15th century.
