What was the first recorded maklokes in the history of the Jewish people. Was it the maklokes Beis Shammai and Beis Hillel about Smicha on Yom Tov?
Answer:
The first machlokes, to my knowledge, is the machlokes concerning semichah between Yosi ben Yo’ezer and Yose ben Yochanan, as cited in the Mishnah in Chagigah (2:2).
