1. Henry IV

The monarchy in France was made strong by:

1. Henry IV: Henry IV, also known as Henry the Great, was a French King who played a significant role in strengthening the monarchy. He was responsible for ending the French Wars of Religion by issuing the Edict of Nantes in 1598, which granted religious toleration to the Protestant Huguenots. This helped to unify the country under a single monarch and stabilize the government.

2. Philip II: Philip II, also known as Philip Augustus, was a medieval French King who ruled from 1180 to 1223. He significantly expanded the territory of France, reclaiming parts of Normandy, Touraine, and Anjou from English control. His military victories and political reforms helped to consolidate and strengthen the monarchy.

It is important to note that Otto the Great (2) was actually a German king, not a French king. As for Gregory (4), it depends on which Gregory you are referring to. Please provide more context so I can provide an accurate answer.
