Spock was born in Shi'Kahr on Vulcan at the Science Academy to a human mother and a Vulcan father on November 12, 2231. His mother was a teacher named Amanda and his father was an Ambassador to the Federation named Sarek. When Spock began school at the age of four, the taunting began. The other children would tease him and attack him because of his human side. Spock was always getting into fights with the other boys. When he was seven, he came home after a fight and was scolded by his father. Sarek told him that he would be very dissapointed if he did not pass the kahs wan, a test of maturity that all Vulcan children must do. So, Spock set out on his own a month before he was suppossed to, to take the test. A le matya, a large cat-like creature with poisonious teeth and claws, attacked him but I-Chaya, hi pet sehlat was there and defended him. Spock's cousin Selek (who turned out to be the older Spock) also helped and Spock was returned home safely. A month later, he passed his kahs wan. Not long after that, Spock was bonded to another seven year old named T'Pring. Later, when he experienced the pon farr and returned to Vulcan to marry her, she choose the kunut kali fee, in which she choose Captain James Tiberious Kirk to fight Spock for her. Spock won, after thinking that he killed Kirk and handed T'Pring over to her lover, Stonn. Kirk was not dead though, it had just appeared that he was.
When Spock was eight-teen, he signed up for Star Fleet against his fathers wishes. Sarek had wanted him to go to the Science Academy, and he was outraged that Spock had applied for Star Fleet behind his back. Sarek declared Spock vrekesht, or disowned him. This caused them to not speak as father and son for eight-teen years. Sarek knew he had been to harsh with Spock but he was to stubborn to admit it.
Spock graduated from the Academy when he was 19 years old. Five years later, he was transfered to the USS Enterprise as Captain Christopher Pike's second officer. After 10 years, the command of the Enterprise was transfered to Captain James T. Kirk. Spock served with Kirk for the next 37 years.
Sometime in the 24th century, Ambassador Sarek handed over the title of Ambassador to Spock. He accepted it. In 2366, at the age 202, Sarek died. Spock was on Romulus at the time and Captain Jean-Luc Picard, of the USS Enterprise D, disguised as a Romulan, went to Romulus and informed Spock of his father's death. Spock had been trying to reunite the Romulans and the Vulcans. He had hoped that they could become a single race again. As far as anyone knows, he still resides on Romulus now.
