A native of the planet Korugar in space sector 1417 (as the Guardians designate space), Sinestro's dedication to preserving order originally manifested in his previous career, an anthropologist specializing in reconstructions of ruins of long-dead civilizations. One day while he was on one such site, a Green Lantern named Prohl Gosgotha crashlanded into the site, injured and apparently dying. He quickly gave his ring to Sinestro, just in time for Sinestro, who barely even understood what the ring could do, to defend himself from the Lantern's pursuer, a yellow-clad Weaponer of Qward. However, Sinestro had to destroy the very ruins he had spent loving care restoring, to crush the Qwardian. Afterward, Gosgotha turned out to still be alive, and asked for his ring back to keep him alive long enough to get help. Sinestro, knowing this would mean not being a Green Lantern himself, instead allowed him to die and took over his post, the Guardians unaware of his actions. In Green Lantern #45 we see for the first time his wife in a flashback and that it is, in fact, the sister of Abin Sur.
His desire for order did well by him in the Corps, and initially led him to be considered one of the greatest Green Lanterns. As the years passed, he became more and more fixated upon not simply protecting his sector, but on preserving order in the society of his home planet no matter the cost. Eventually he concluded that the best way to accomplish this was to conquer Korugar, and to rule the planet as a dictator.
When Hal Jordan joined the Green Lantern Corps, Sinestro was assigned to be his instructor. Jordan was horrified at his new mentor's totalitarian methods, though Sinestro maintained that his iron-fisted rule was necessary to protect his people from alien forces. During his training, Jordan helped Sinestro repel an attempted invasion of Korugar by the alien warlords known as the Khunds. When Jordan called for help from the other Green Lanterns, Sinestro's dictatorship was exposed and he was forced to appear before the Guardians for punishment. Katma Tui, the leader of a Korugarian resistance movement who felt that Sinestro's "protection" kept her people from growing as a society through contact with other alien races, was recruited as his replacement in the Corps. Though Katma Tui eventually grew into one of the most respected Green Lanterns, she and the rest of Korugar initially resisted her appointment to the Corps; due to Sinestro's actions, Korugar had come to consider the symbol of the Green Lantern Corps an emblem of terror and oppression.
For using the power of the Green Lantern to instill fear rather than combat it, the Guardians banished Sinestro to the antimatter universe—a counterpart to the "real" universe made up of "negative matter." Sinestro ended up on the Antimatter world of Qward, that universe's counterpart of the Guardians' homeworld Oa, which was ruled by a race of warriors and scientists known as the Weaponers of Qward, who bore a fierce hatred of the Guardians and all Green Lanterns. By exiling Sinestro to a world ruled by evil beings who specifically hated him as a Green Lantern, the Guardians hoped to humble him. Their attempt at punishment would be a major miscalculation, however. Sinestro believed himself to have been wronged by his former masters, and now hated them just as much as the Weaponers did. Through their mutual hatred of the Guardians, Sinestro and the Weaponers became allies, with the Weaponers offering to help Sinestro gain revenge on the Guardians and the Corps.
Creating a yellow power ring for Sinestro to use, the Weaponers sent him back to the "positive matter" universe to seek his revenge. Sinestro quickly became the Green Lantern Corps' most powerful nemesis, partially due to a weakness in their power rings that prevented them from directly affecting the color yellow.
