Maeda Toshinaga sided with the Eastern forces at Sekigahara in 1600, in sharp contrast to his father Toshiie, who had maintained a pro-Western stance as one of the Five Elders. This decision arose from personal animosity toward Ishida Mitsunari and a pragmatic political calculation about the Tokugawa. The Maeda, the largest outside daimyo after the Tokugawa with their million-koku Kaga domain, secured Kaga's survival through Eastern participation. Toshinaga continued demonstrating loyalty to Ieyasu after the war, ensuring the Kaga million-koku domain's safety. The contrasting choices of father Toshiie's Toyotomi loyalty and son Toshinaga's Tokugawa submission symbolize the Maeda's complex position.
