A Rebbe
There Always Was A Concept of a Rebbe For as long as Jews existed as a people, they always had a Rebbe. Starting with Moshe Rabeinu, who led the Yidden out of Mitzrayim to receive the Torah and throughout the 40 years that they travelled in the wilderness, through Yehoshua, who led the people in battle to conquer Eretz Yisroel, the Shoftim, the Nevi'im, and kings that followed until the destruction of the first Beis Hamikdash. During golus there was Daniel, Mordechai, Ezra, and Nechemiah. Once the Sanhedrin was established, there was the Nasi of the Sanhedrin, and in the diaspora, there was the Reish Galusa.
