Federation-Klingon War of 2405-2410

The 25th century Federation-Klingon War (also referred to as the Third Federation-Klingon War) began in early 2405 following a period of declining relations between the United Federation of Planets and the Klingon Empire in the latter years of the 24th century. 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, the conflict had mostly resolved by mid-2409 in the face of mounting threats from outside the region and the war officially ended early the next year.
