Worf, son of Mogh and later adopted into the House of Martok, was one of the most influential Klingons in the galaxy in the mid-late 24th century. Worf was born in 2340 on Qo'noS, but Mogh moved his family to the Khitomer colony sometime before 2346, when it was attacked and destroyed by the Romulans. Mogh was killed on Khitomer, but Worf was adopted by a propulsion crewman on the USS Intrepid, Sergei Rozhenko.
He was then raised as the Klingon child of two human parents on a small human colony world called Gault. This made for a difficult childhood; Worf found it hard to bridge the gap between his Klingon heritage and his decidedly un-Klingon circumstances. In 2357, he made the decision to join Starfleet Academy, and he graduated in 2361 as the first Klingon to join the Federation Starfleet.
By 2364, Worf, ranking Lieutenant Junior Grade, was serving on the USS Enterprise-D as a Junior Security Tactical Officer under the command of Captain Jean-Luc Picard. Upon the death of Lieutenant Tasha Yar, he was promoted to Chief Tactical Officer and Chief of Security. In 2366, he became involved with K'Ehleyr, a Human-Klingon emissary who became the mother of his child, Alexander. She was later murdered by Duras, and Worf took his life in vengeance.
Later in that year, Worf's life was thrown into turmoil when the Klingon Empire announced that Mogh had betrayed the Klingon colony at Khitomer and given the Romulans information to destroy it. Chancellor K'Mpec had approved this finding on the assumption that no one would challenge it, but Worf and his brother Kurn appeared before the Klingon High Council to protest. Worf discovered that it was indeed Duras who had committed treason, but the Empire feared his powerful house and did not wish to condemn him. Worf agreed to accept discommendation to preserve the Empire.
This left Worf without any real place in Klingon society, but when the Klingon Civil War erupted in 2367, he resigned from Starfleet and fought on the side of Gowron against the forces of the Duras family. With the help of Captain Jean-Luc Picard, Worf and other Gowron supporters revealed Romulan assistance to the Duras cause. This collapsed support for Duras, and Gowron won the chancellorship. He then restored the honor of the House of Mogh for their help in the war. Worf returned to Starfleet without incident.
In 2371, Worf was promoted to Lieutenant Commander and later reassigned to Deep Space Nine as strategic Operations Officer. He again became a player in galactic politics as the Federation tried to avert war between the Klingon Empire and the Cardassian Union. Worf was their best link to Gowron, but his efforts were unsuccessful. The Klingons broke the Khitomer accords and attacked both the Cardassians and the Federation. Worf again received discommendation, but remained loyal to the Federation. He remained an integral part of Deep Space 9 and a valued asset against both the Klingons and later in the Dominion War.
By 2373, Worf was married to Jadzia Dax and had participated in the battle at Sector 001 against the [[Borg]. He also fought the [[Borg] temporal incursion into 2063. Amidst all this, he was also a veteran of the Dominion War, and had been adopted into the House of Martok. He was captured by the Breen with Ezri Dax in mid-2375, and was freed by Legate Damar as part of his resistance to the Dominion.
In the later stages of the war, he became disillusioned with the leadership of Gowron, citing his faulty battle planning and poor strategies. Worf challenged Gowron to combat and killed him; by right he was acclaimed the new Chancellor of the Klingon High Council. However, Worf stepped aside and nominated Martok to the position. After the war, Martok asked that Worf be appointed Ambassador to the Klingon Empire (the measure was amusingly vengeful).
Worf (appears to have) left that position to rejoin his old crewmates on the USS Enterprise-E as Tactical Officer and probably Chief of Security in 2379!
