Stephen the Great is thought to be the best voivode of Moldavia. Stephen ruled for 47 years, an unusually long period for that time. He was a successful military leader and statesman, losing only two out of fifty battles; he built a shrine to commemorate each victory, founding 48 churches and monasteries, many of which have a unique architectural style. Stefan's most prestigious victory was over the Ottoman Empire in 1475 at the Battle of Vaslui, for which he raised the Voroneţ Monastery. For this victory, Pope Sixtus IV nominated him as verus christianae fidei athleta (a true Champion of the Christian Faith). After Stephen's death, Moldavia also came under the suzerainty of the Ottoman Empire during the 16th century.
