Naruto was born in the leaf village shortly after the nine-tailed fox was sealed in him. But that's another story you'll have to find out for yourself. ;]
Soon after Naruto was born, the Nine-Tailed Demon Fox attacked Konoha. Minato rushed to the village's help, where he and Gamabunta faced off against the Nine-Tails, but the beast's power could not be matched. Recognizing that the Nine-Tails was being controlled by Madara Uchiha, Minato decided to defeat it and give Konoha the means to combat Madara if he should ever attack the village again. He used the Dead Demon Consuming Seal to seal the Nine-Tails into Naruto's body, hoping that Naruto would someday be able to make use of its power. The act cost Minato his life, and he died as the village's greatest hero.
