István the Saint, also known as Saint Stephen, was the first King of Hungary, reigning from 1000 to 1038 AD. He is credited with establishing the Christian state of Hungary and played a crucial role in converting the nation to Christianity. His reign marked the beginning of the Hungarian monarchy and the integration of Hungary into the broader European community. Saint Stephen is venerated as a saint in both the Roman Catholic and Eastern Orthodox churches. His feast day is celebrated on August 20, which is also a national holiday in Hungary. He is often depicted holding a crown and a church, symbolizing his dedication to both the state and the Christian faith.
