Osman Ghazi, the founder of the Ottoman Empire, is historically known to have had several wives. However, the most widely accepted accounts suggest that he officially had one primary wife, Malhun Hatun. He may have had other wives or concubines as was common during that era, but Malhun Hatun is often highlighted due to her significant role in Osman’s life and the lineage of his descendants. Additionally, the historical records from that time are not always precise, and the practice of polygamy was prevalent among leaders and nobles.
