Angus Mengsk

Angus Mengsk was a famous political figure in the Koprulu Sector and father of Arcturus Mengsk. He was originally from Korhal IV.

Korhal was one of the oldest Terran Confederacy colonies and a world of affluence. Its people, however, resented their affiliation with the corrupt Confederate senators.

Tensions arose between the colonists and the Confederates as the citizens began to revolt against the local Confederate militia. The Confederates imposed martial law, but the revolt refused to die out.

Leader of the Rebellion
Korhalian Senator Angus Mengsk became a leader of the Korhalian revolt, issuing fiery statements declaring that the Confederacy no longer held any claim over the world of Korhal.

The revolt was successful enough to drive the Confederates from the planet, as the Confederacy decided on a new tactic. Three ghost assassins killed him and most of his family in the capital city, Styrling, and his head was never found. This did much to weaken the revolt.

Legacies
The murder of Angus Mengsk murder prompted his son, Arcturus, to follow a path of vengeance against the Terran Confederacy.

Angus Mengsk's friend, the Umojan diplomat Ailin Pasteur, would assist Arcturus Mengsk in becoming the next leader of the Korhalian Rebellion.

The most important ghost of the trio was Sarah Kerrigan, whom Arcturus Mengsk tracked down, originally intending to kill her in revenge for the death of his father. However, after retrieving the then-amnesiac Kerrigan from an experiment involving xenomorphs, he decided she would be more useful as a follower.

Mengsk murdered another one of the ghosts (who was wounded and amnesiac at the time), prompting Kerrigan's ire. Mengsk then admitted that she had killed his father, but he forgave her, saying she gave him hope. Kerrigan became extremely loyal to Mengsk as a result.
