In "Naruto", who is Naruto's father? Why did he die?

It was the Fourth Hokage Namikaze Minato, who had memories before Jiraiya's death. Naruto's mother's name was Uzumaki Kina, and Naruto's name came from a story originally written by Jiraiya. The name of the protagonist (not Intimate Paradise), Yondaime chose this name because he liked the character of the protagonist very much. The nine tails released to seal Uchiha Madara died.
