齋藤道三
In 1549 young Oda Nobunaga (1534–1582), who would later become a major daimyō of Owari Province, Japan and would initiate the unification of 16th century Japan, was married to Nōhime, the daughter of Saitō Dōsan, leader of the rival Saitō clan of neighboring Mino Province. Nobunaga was the second son of Oda Nobuhide, head of the Oda clan, who was at that time fending off opponents on the northern and eastern borders of Owari Province, matters that were complicated by internal dissent. Saitō Dōsan, lord of Mino, was a strong and ruthless leader, but internal strife had begun to split the Saitō into factions. Both clans needed some respite to deal with more pressing problems and thus the political marriage of Nobunaga and Nōhime brought an end to the clans' rivalry and their border skirmishes.
