What did hugh capet and his heirs accomplish in france?

Hugh Capet and his heirs strengthened the monarchy in France.

Explanation:

Hugh Capet was king of France from 987 to 996. He was born into a powerful, noble family of which two members already held the French throne during the 800-900s. He inherited his father's land and became the most powerful nobleman of his time.

Between 978 and 986 Hugo succeeded in maintaining his dominant power over the weak Carolingian king Lothar through alliances with the German emperors Otto II and Otto III. Already in 985 Hugh ruled the kingdom as if he were king. Lothar and his son died in 987 and the Archbishop of Reims convinced a group of noblemen to choose Hugh Capet as the new king. He was crowned on July 3, 987 in Noyon, Picardy and became the ancestor of the Capetian lineage.  

The dynasty's strength was its good relationship with the Catholic Church. The king influenced the choice of bishops and the benefits of administering church property. For the Church, he was the support and guarantor of order in the state.

His reign supposed the feudalization of the currency. The weakness of royal power led many bishops, lords and abbeys to mint their own coins, and the practice of weighing coins to check their value was extended.
