More like an idealized ruler that people hoped would appear to save them.

I don't think that the original was ever called a messiah.

The most important things to this Servant's identity:

Confusion with Genghis Khan geographically, although that came after more of the world between the near east and the far east was explored by Europeans. Originally, he was thought to be from India, but people kept moving where they thought he was when they didn't find him in one place.

"Three Wise Men" connection. There's something in this Servant's original legend about them.

The fact that a group of Europeans eighty years before Genghis Khan really needed some outside help in order to keep their hold on a holy city, but, this hero wasn't real despite what people thought (there was a trigger to give this hero a name in the public consciousness [the name was probably derived from a 1st century figure who some think might've authored the Book of Revelation], and people believed in it enough that a very important figure tried to send a missive... to a nonexistent person).
