During Dōsan's reign, his daughter Nōhime married Oda Nobunaga, the heir of the fast rising clan in the neighboring Owari Province, with the hopes of an alliance of the two families' would present a powerful front against their competitors. However, it would be Nobunaga that eventually absorbed Dōsan's Saitō clan in the mid-sixteenth century, as Dōsan had done to his retainer. It was during Nobunaga's reign of power that the area finally received its modern name. After consulting with a Buddhist priest, Nobunaga renamed the village and the surrounding Mino Province to Gifu in 1567. He took the first character (岐 gi) from Qishan (岐山), the legendary mountain from which most of ancient China was unified. The second character (阜 fu) means base of the mountain and comes from Qufu (曲阜), the birthplace of Confucius. Though he was not originally from the area, Nobunaga chose to use Dōsan's castle and mountain as his base of operations, which he renamed Gifu Castle and Mount Kinka, respectively.
