By reading the book by Basset For God and Kaiser, the author seems to be pretty fond of the ruling of Maria Theresa. It is pointed out that Maria Theresa an influential Empress of the XVIII century. I was wondering two things: 1) whether if this is considered true in the western countries and 2) if there are Kings or Emperors of the same period, in the East, whose influence could be considered to be the same order of magnitude as Maria Theresa was to her Empire.

Since none of the Mughal Padishahs after Auragenzeb (died 1707) can be considered a really great Mughal I think that is pretty much the entire list of contemporary or near contemporary monarchs who might be compared to Maria Theresa, though specialists might possibly think of a few others.
Thus if you want to do a comparative ranking of Maria Theresa with contemporary monarchs these are her main competition.
