Petru Rares defeated the Polish army at the Battle of Obertyn, securing control over the Pokuttya region. The victory was a major military success, but it did not lead to lasting territorial gains as Poland later regained the area.

Petru Rares was deposed by the Ottoman Sultan Suleiman the Magnificent after refusing to comply with Ottoman demands. He fled to Transylvania, and the Ottomans installed a more loyal ruler,

Petru Rares regained the Moldavian throne with the help of the Ottoman Empire, after pledging loyalty and increased tribute. He ruled for another five years, but his power was significantly reduced, and he remained an Ottoman vassal.

King Seongjong founded national Confucian academies and local schools throughout Goryeo, promoting Confucian learning and ethics. This educational reform strengthened the civil service examination system and fostered a Confucian scholar-official class that shaped Goryeo governance.

Seongjong issued a comprehensive legal code based on Confucian principles, systematizing Goryeo's laws and administrative regulations. This code provided a legal framework for governance, criminal justice, and social order, influencing Korean law for centuries.
