The path to Tokugawa dominance began with Ieyasu's patient accumulation of power during the chaotic final decades of the 16th century, as he skillfully navigated the complex alliances and conflicts that characterized the age of warring states while building a secure territorial base in the Kanto region that would provide the foundation for his eventual supremacy. Unlike more impetuous rivals who sought immediate gratification through military conquest, Ieyasu demonstrated remarkable strategic patience and political acumen, carefully timing his moves to maximize advantage while avoiding premature confrontations that might have destroyed his growing power base. His service under both Oda Nobunaga and Toyotomi Hideyoshi provided valuable experience in military organization and political administration while his gradual expansion of territory and influence created the resources necessary for the final struggle for national hegemony.
