Federation-Klingon War of 2405-2410

The fifth Federation-Klingon War took place between 2405 and 2410. Initially a dispute over the extent of Undine infiltration of the Alpha Quadrant that escalated into a land grab by Chancellor J'mpok of the Klingon Empire, it ground to a halt by mid-2409 in the face of mounting threats from outside the region occupied by the two superpowers, and was officially ended early the next year.
