Gowron, son of
M'Rel, became
Chancellor of The
Klingon Empire in
2368 (
Redemption, part II)
He was later killed by Worf (Tacking Into the Wind) because he (Gowron) was purposefully having Martok fight hopeless battles against the Dominion in order to lower Martok's political position.
Bad Gowron! No gagh for you!
