Final answer:
The information provided does not identify any major achievements for 'Frances de Sales' specifically. Instead, various historic figures connected to France are noted, such as Francis I's role in exploration, Napoleon's educational reforms, and the spread of Catholicism in New France and beyond. The question may be mistaken or require clarification to provide a factual answer.
Step-by-step explanation:
The major achievement of Frances de Sales is a matter that could refer to different historical figures who bear the name Frances or Francis, relating to various contributions in French history. However, as the name is not connected to a specific historical figure in the provided information, it is not possible to identify any individual achievements for 'Frances de Sales'. Instead, let's explore Francis I of France, whose achievements in the early 16th century are notable. He sponsored voyages by Giovanni da Verrazzano and Jacques Cartier to the New World, aiding France in overseas exploration and maintaining France's Catholic identity by signing the Concordat of Bologna.
Another significant figure, Napoleon Bonaparte, contributed to the French educational system by inventing the lycée, which is still an integral part of French secondary education. This achievement was part of Napoleon's broader reforms to establish an efficient and powerful state. Moreover, during his reign, he signed a Concordat with the Pope, which restored the Catholic Church's position in France but maintained religious tolerance for minorities.
Catholicism's influence can also be seen in New France (Canada), where the French aimed to convert native populations and even attempted to canonize a Native American convert, Kateri Tekakwitha, who was eventually declared a saint in 2012. The legacy of Catholic missions in the colonization of the New World is marked by figures such as Bartolome de las Casas, who advocated for the natives' dignity and rights.
Lastly, the arts in France also have a rich history, with the 13th century giving rise to notable illuminations that influenced the public image of Louis IX, leading to his eventual sainthood. France's cultural and historical achievements are wide-ranging and continue to resonate today.
