He is inlove with Elena Gilbert.
As the bad boy of the show, he goes by this motto: "If you're gonna be bad, be bad with a purpose. Otherwise, you're just not worth forgiving."
Damon was born to Giuseppe Salvatore and an unnamed mother on June 28th, 1840 in the small town of Mystic Falls, Virginia. His younger brother Stefan Salvatore is six years younger than him, and the two were very close. He joined the Confederate Army at some point, coming back when he was on leave to spend time at the Salvatore Estate. It is unclear when Damon first met Katherine Pierce, but he left the Confederacy and returned to Mystic Falls to spend more time with her. His father disapproved of what he considered Damon's poor sense of duty.
It is uncertain how or when Damon found out that Katherine was a vampire, but unlike Stefan he did not fear or reject her, and willingly drank her blood. She once demonstrated to him one of her tricks for securing victims: lying in the middle of a road to stop any travelers that may come to pass. Though he showed an initial hesitance, Damon even kissed her while a victim's blood still stained her lips.
Damon wanted to give up his human life and spend an eternity with Katherine, and he begged Stefan to keep the secret from their father, who was a member of the Town Council and a vampire-hater. When Stefan inadvertently revealed that Katherine was a vampire, she was taken away by the townspeople. Their father was furious and scolded Damon for trying to conceal her secret and protect her. Damon was furious with Stefan, but Stefan agreed to work with him to rescue her. In the midst of their daring plan, they were both shot and killed by Giuseppe, who was ashamed of his sons for sympathizing with and loving a vampire. They both died with Katherine's blood in their systems, but Damon awakened first and witnessed the burning of Fell's Church, where the townspeople had imprisoned the vampires, including Katherine. Damon awakens after dying.When Stefan awoke the next morning, Damon told him that Katherine's death meant his reason for living was gone, and he wouldn't complete his transition into a vampire. Later that day, when Stefan returned after being unable to resist feeding on his own father, and inadvertently completing the transition, he forced Damon to drink from a young woman's neck, causing Damon to also complete his transition. He promised Stefan an eternity of misery, not for making him turn but for the fact that Katherine had turned Stefan as well, instead of just Damon. At some point Damon received a daylight ring fromEmily Bennett. She told Damon that she had spared the vampires in the church, which Damon kept secret from Stefan until 145 years later, when he would be able to free Katherine from the church.
Damon and Stefan in 1912Damon saw Stefan in 1912 for the first time since they transitioned; both had returned to Mystic Falls for their nephew's funeral. After an initial hesitance, Damon agreed to have a drink with Stefan and catch up. When he was feeding on a human alone, the vampire Sage found him and commented on his lack of enjoyment for the feed. Damon seemed content to feed just enough to survive, but Sage encouraged him to enjoy it, to take pleasure in being a vampire. Once he was persuaded, he tried to get Stefan to enjoy the feed, and talked him into feeding on human blood again. Stefan fed so hard on his victim that he tore her head off, shocking both brothers. Furious with Damon for making him drink human blood, he ran off and Damon did not pursue him.

At Lexi's insistence, Stefan sought to make peace with his brother before shipping out to the North African front of the war. After an initial hesitance, Damon seemed happy to reunite with his brother after thirty years apart, and the two spent the evening talking. Damon even suggested he might join Stefan and leave for war with him, but Lexi made it clear she did not approve of the idea. Her concerns seemed warranted especially after Charlotte brought a bleeding victim to the bar where they were talking and Stefan started to lose it at the sight and smell of human blood. Later, Damon was all ready to ship out with Stefan when Lexi talked him out of it, citing his profligate lifestyle and how Damon's behavior would not be good for Stefan's rehabilitation. Realizing she might be right, Damon decided not to go, and he left the train station without explaining to Stefan.
