why did catherine de medici agree for her daughter, margaret, to marry henry of navarre?

Question

i need the political and religious details.

Answer 1

Henry's marriage was believed by most to be an effort to bring religious peace to the kingdom.

Marguerite was made to marry Henry de Bourbon (later Henry de Navarre and eventually Henry IV), the son of the Protestant Jeanne d'Albret, Queen of Navarre, a marriage that was designed to reunite family ties and create harmony between the Catholics and Huguenots. Although Henry's mother, Jeanne d'Albret, Queen of Navarre, opposed the marriage, many of her nobles supported it, and the marriage was arranged. Jeanne d'Albret died before the marriage was concluded.
