I found the easiest way to get this achievement is to play as Austria and get 7 of the HRE reforms, which should leave the entire HRE as your vassals (without any of them using up a diplomatic relations slot). Using this to your advantage, conquer from all the nations that surround you and never get the last reform until you get this achievement.
