Saint Stephen I was the first King of Hungary, reigning from 1000 to 1038. He is known for establishing the Christian state in Hungary and played a crucial role in converting the nation to Christianity. His efforts helped to unify the various tribes in the region and laid the foundation for a stable monarchy. Stephen was canonized as a saint by the Catholic Church in 1083, and his feast day is celebrated on August 16. He is often depicted holding a crown and a church, symbolizing his dual role as a ruler and a promoter of Christianity in Hungary.
