Question

What was the names of french legislators who sat in the center of the meeting hall, those who wanted reforms but not extreme or excessive.

There are radicals, conservatives, and I don't know what these people are called.
Question relates to the Late 1700s to early 1800s.

Answer 1

You might simply want the term "moderates". But for a full discussion see:
C.J. Mitchell's article "Political Divisions within the Legislative Assembly of 1791" in French Historical Studies (1984)
