Before Gaara's birth, his father ordered Chiyo to seal the One-Tailed Shukaku within him, in hopes that Gaara would become the ultimate weapon for Sunagakure. Because a sacrifice was needed, Gaara's mother, Karura, was used. Before she died, Karura cursed Sunagakure, hoping Gaara would avenge her death. Gaara was trained by his father, but raised mainly by his maternal uncle, Yashamaru. Because of the power of Shukaku, the villagers of Suna hated and feared Gaara, seeing him only for the monster sealed within him.
