The Uzumaki Clan were distant blood relatives of the Senju Clan, descendants of Asura, and their members excelled at Sealing Jutsu.
Ashina Uzumaki was the clan head who led the Uzumaki Clan. Through his great strength, he founded the Land of Whirlpools and Uzushiogakure, becoming its leader.
Later, under his leadership, the clan joined Konohagakure and signed a treaty of friendship with the First, Hashirama Senju. To symbolize the two nations' generations-long friendship, the Konoha High Command had the Uzumaki Clan's emblem printed on Jonin uniforms. In this way, the two nations maintained a deep friendship and bond.
But other clans feared the Uzumaki Clan's Sealing Jutsu, and many nations and clans launched attacks on the Land of Whirlpools. The country was ultimately destroyed, and the survivors concealed their identities and scattered across the world.
Nagato Uzumaki's mother, Fuso, was among those who fled to the Land of Rain at the time. She concealed her identity and began living as an ordinary civilian.
Later, she started a family with a civilian from the Land of Rain and gave birth to Nagato Uzumaki.
Inside Konoha's Hospital Department, Nagato Uzumaki stood outside the delivery room of Kushina, the Nine-Tails Jinchuriki. He wore a black cloak embroidered with red clouds, and his long red hair fell over his shoulders.
Now, scattered among his long hair were patches of white strands. They were the result of his body's chakra being depleted.
Members of the Uzumaki Clan with pure bloodlines all had red hair. When their chakra was overdrawn, their hair turned white.
The Uzumaki possessed powerful life force, so most lived long lives and had far more chakra than ordinary people. This made them suitable as Tailed Beast Jinchuriki; even if a Tailed Beast was extracted, they wouldn't die immediately.
