The holy and right-believing Prince Saint Stephen the Great (Romanian: Dreptcredinciosul Voievod Ştefan cel Mare şi Sfânt) was ruler of Moldova (in modern-day Romania) from 1457 to 1504. He was a great statesman and military tactician as well as being a devout Orthodox Christian. He was responsible for defending Moldova against the Ottoman invasion, building a church or monastery in thanks to God after each victory.
