Senju Clan

The Senju clan (千手一族, Senju Ichizoku) was a group of shinobi that were the strongest, feared and most respected clan above all other clans in the ninja world during the war-torn era before the founding of the hidden villages. Together with their rivals — and distant relatives through a common ancestor — the Uchiha clan, they are responsible for founding the first hidden village named Konohagakure and making the village into what it is today.

The Senju clan descended from the younger of the two sons of the Sage of the Six Paths who was born with the "body" of the Sage, inheriting his father's life force, physical energy, and believed that love was the key to bringing peace to the world. The Sage grew to favour the ideals of his younger son over those of his older son, who believed that power alone was the true key to finding peace. Therefore, on his deathbed it was the younger of the two brothers that the Sage chose to name as his successor. The elder brother, bitter and hateful at having being denied what he felt was rightfully his to inherit, attacked his younger sibling. The Uchiha clan would descend from the elder brother, resulting in the bitter centuries-long rivalry between the Senju and the Uchiha. While undisputed, the Senju's legendary rivalry with Uchiha clan was taken advantage of by countries that hire their services.

The Senju clan gained their fame in the era before the founding of the hidden villages. Where other clans focused on mastering one particular set of skills, the Senju were prodigious in all skills, from ninjutsu, to taijutsu, and genjutsu. Because of this, they were known as "the clan with a thousand skills" (「千の手を持つ一族」, "sen no te o motsu ichizoku"), which gave them their name "Senju" (千手; Literally meaning ""a thousand skills", "a thousand hands"").

The Senju and the Uchiha created a permanent settlement for shinobi within the country: Konohagakure. The first of its kind, the system along with the name inspired more countries to have their own hidden village per country, ending the Warring States Period

It is unknown if the Senju clan still exists due to the fact if anyone bears the last name "Senju" Their legacy however, lives on strongly in the hearts of the people of Konoha.
