Anna Jagiellon was elected Queen of Poland in 1575. While many women rose to power by birth or marriage, Anna was actually chosen by nobles to rule. This achievement remains surprising.
Today, female world leaders are still rare. According to recent data, only about one in four national parliament members globally are women: 27.2% of parliamentarians in single or lower houses, up from 11% in 1995.
As of January 1 2025, in 25 countries women serve as heads of state or government. That number has improved over the past few decades, but men continue to dominate elected office. Anna’s story, set over four centuries ago, shows a woman could secure power through a vote, even in an era when female rulers were nearly unheard of.
