Now, as lords of Sendai, they are still all of those, even after centuries of relative peace. They have done this by political guile, implacable enemies, and fierce warriors. Given control of the Date province, and taking the name as their own, they survived centuries of turmoil. Even before then, the Date had been a noble and notable family of samurai, beginning as the Isa clan under the Minamoto.
