The Myth of the Historical Christ

At what point would you say Christians held the majority of them held to the historicist view? I mean, I would probably say before the turn of the second century. It's very obvious that there was a switch to believing in this more historical Christ. And yet it seems just odd to me that once we get to the end of the first century and going forward, you don't have like this original sect of mythicist Christians promoting their views.
