More and more people like to go to Europe to play, mainly in pursuit of discounted luxury goods there and feel the strong historical background. The history and culture of Europe are mainly reflected in three aspects: there are many churches, museums and castles.

Whenever the tour guide tells you that this manor or castle belongs to nobles and kings such as Henry IV and Louis xi, you will always be at a loss. Even if I remember at that time, returning to another city would confuse two contemporaries with the same name and surname. What a big head! Why did Europeans have so many duplicate names in feudal times? Sometimes even "generations" are the same.

In medieval Europe, names were named according to the date of naming, and godparents were named according to the list of saints. Louis, Peter, John, Philip, Charlie, James, etc. They are all common names used by Christians, and each name has a different meaning. For example, Charlie Charlie is a nickname for Charles, which comes from a Germanic name and means a manly warrior.

For another example, Jacob comes from the Hebrew word "Jacob", which means God bless his followers. Many disciples of Jesus are called "James". John John also comes from Hebrew, which means that God is merciful. So most Europeans have Christian saints after their names, and they all have the meaning of religious blessing. Facing the present situation that China people love to take foreign names, it is best to know the meaning before taking them.

There are many cases of duplicate names. In addition, in order to reflect the family inheritance, each European royal family can only choose the name of its ancestor when naming, and then explain the first generation. Apart from boasting about one's origins, it is really difficult because there are only a few common surnames (for example, the name of the French Bourbon monarch is between Louis and Philip).

"Which generation" is mainly marked in aristocratic genealogy and historical documents, which means "the first person to use this name under this title", such as Charles Louis Napolé on Bonaparte, which means "the third king named Napoleon in French history".

But "which generation" does not necessarily represent several generations, but only the order of inheritance. Charles Louis Napolé on Bonaparte is not the grandson of Napoleon I, but his nephew. Just because he used the name Napoleon as emperor, and the first two people used the name Napoleon as emperor (Napoleon himself and his son Napoleon II), he was Charles Louis Napolé on Bonaparte.
