The main reasons why France was able to obtain the Spanish throne can be attributed to the following points:
Geographical proximity: France and Spain are geographically close to each other, which has allowed the two countries to have more exchanges and interactions throughout history. During the European Middle Ages, France and Spain were often involved in wars and territorial disputes. This proximity provided an opportunity for France to play an important role in European politics and laid the groundwork for France's advantage in the struggle for the Spanish throne.
Political marriages: During the Middle Ages, political marriages between European countries were a common means of diplomacy. By marrying the Spanish crown, France could strengthen the ties between the two countries and gain influence over the Spanish throne. For example, Charles VII of France during the Valois dynasty brought France and Spain closer together by marrying a Spanish princess. This also gave France an advantage in the future struggle for the Spanish throne.
Religious factors: During the Middle Ages, religious beliefs were a very important factor in the political life of European countries. There were differences in religious beliefs between France and Spain, which provided an opportunity for France to compete for the Spanish throne. There was a contradiction between the Catholic denomination supported by France and the ** sect supported by Spain, and this contradiction provided a pretext for French intervention within Spain. France could use religion to incite opposition in Spain and support its own people to the Spanish throne.
Power and Profit: France's struggle for the Spanish throne was also driven by power and profit. On the one hand, by controlling the Spanish throne, France could expand its territory and influence and improve its position in European politics. On the other hand, Spain's resources and wealth are also attractive, and by controlling Spain, more wealth and resources can be obtained to meet the needs of France domestically.
In summary, France was able to obtain the Spanish throne for a number of reasons, including geographical proximity, political marriages, religious factors, and power and interests. These factors interacted to give France an advantage in the struggle for the Spanish throne and eventually achieved control over Spain. However, it should be noted that the development of history is complex and changeable, and various factors interact to determine the direction of history. Therefore, when analyzing historical events, it is necessary to comprehensively consider the influence of various factors in order to draw more comprehensive and accurate conclusions.
