Although he was a little puzzled by the unusual behavior of his third daughter, Maria, Ferdinand II and the Council of the Kingdom of Castile, after consultation, agreed to marry the third princess, Maria, to King Manuel I of Portugal as his heir.

Because, if Manuel I married another princess of another country as his stepfamily, then Miguel, the only son of Princess Isabella, who was only 6 years old, was likely to be killed by his stepmother. Instead of this, it is better to marry Princess Mary as a continuation. If my sister is a stepmother, she won't hurt Prince Miguel, right?

But they were all wrong, in fact, after knowing that she could replace her sister as Queen of Portugal, Princess Maria had already murdered her sister's only son, Prince Miguel. Of course, the premise is that she can leave the boy first. It wouldn't be worth it if he couldn't keep the boy and kill Miguel. After all, the stepmother killed his ex-wife's child, and it is impossible for the father to be unclear at all. If she hadn't given birth to a boy, she would have killed Miguel and made the Portuguese royal family extinct, and maybe Manuel I would have killed her.

Moreover, Princess Mary is also a person with brains. She believes that before starting, she must show her "loving" side and take good care of Prince Miguel...... Until his own son is born, Miguel, who is a stumbling block, can move away......

In fact, Princess Maria attacked Miguel very early in history. Although he married into Portugal in October 1500. Prince Miguel was finished in August, but since Princess Isabella's death in 1498, Princess Maria has long been the prospective queen of the Kingdom of Portugal, and the two sides have already begun to make relevant preparations. The reason why the wedding was postponed until October 1500 was due to hostility and disputes between the two countries. The main thing is the issue of Indian interests, and the two countries are very unhappy. Therefore, the wedding was postponed.

But in fact, Princess Maria has long been regarded as the prospective queen of Portugal, and has already put her hand into the Portuguese royal palace. She bribed the ladies of the palace who had been married by her former sister, and asked them to "die young" of the young Prince Miguel before her wedding began. In this way, when the prince dies and marries himself, no one will suspect that he did it......

So, Princess Maria is not a good stubble. Moreover, after seeing that his second sister Juani's son Charles V was about to inherit the two great empires of HRE and Spain, he immediately tried his best to marry his daughter Isabella and become the queen of the empire.

In fact, Charles V's marriage suffered a big loss. The Austrian family of the Habsburgs originally planned for Charles V to marry Princess Anne of the Kingdom of Bohemia. Because, when Maximilian I was fighting for Hungary with Vladislas II, he had a pact that once the Kingdom of Bohemia was extinct, the Kingdom of Bohemia and Hungary, including the regions of Silesia and Moravia under the control of the Kingdom of Bohemia, would be inherited by the Habsburgs.

In order to realize the dream of annexing the kingdoms of Bohemia, Hungary, Silesia and Moravia, the Austrian family of the Habsburgs supported the marriage of Charles V and Anne of Bohemia. Although Vladislas II had an only son, Lajosh, he was not in good health. The members of the Habsburg family in Austria were looking forward to the early death or extinction of Lajos II. In this way, the Habsburg possessions could be extended to the neighboring kingdoms of Bohemia, Hungary, Silesia, and Moravia.

It's just that, because of pressure from the Spanish royal family, Charles V married Princess Isabella, the daughter of Princess Maria. Then, Charles V's younger brother, Ferdinand, married Anne of Bohemia......

This laid the foundation for the dissolution of the alliance between the HRE and the Spanish Empire – Lajos II was indeed dead, and the kingdoms of Bohemia, Hungary, Silesia, and Moravia were all part of the Habsburgs. However, it was Ferdinand, not Charles V......

The problem then arises, Charles V wants his son Philip II to inherit both the HRE and the Spanish Empire. However, after inheriting the kingdoms of Bohemia, Hungary, Silesia, and Moravia, Charles V's younger brother Ferdinand was emboldened to compete for the throne of the Holy Roman Empire.

Moreover, because he was afraid that Philip II, the son of Charles V, would have both HRE and Spain, he would suppress the German vassal states like his father. So, the Seven Electors chose Ferdinand as Emperor of the HRE and King of Germany. Even though Charles V was willing to give up the real power of the German king and only let Philip II have the title of emperor, the seven electors refused to agree. In this way, the union of Shinra and Spain, which had beaten France and captured the king of France, had to be dissolved because of a marriage that had been chosen wrong......

If it had not been for the operation of Princess Maria, who sent her daughter to be empress, and had followed the advice of the Habsburg family of Austria to marry Charles V to Anne of Bohemia, then the great alliance between the HRE and Spain would have continued to exist, and Germany would have been able to achieve de facto unity. After all, Spain's gold and silver gains in the Americas are not for fun.

After the dissolution of the union between the HRE and Spain, the Habsburgs of the HRE were in a difficult situation, while the Spanish Habsburgs continued to dominate until the defeat of the "Eighty Years' War" and the "Thirty Years' War", when they began to decline. It can be seen from this that whether a country is strong or not is not only related to the combat effectiveness of the armed forces, but also to its financial strength.

At the beginning, Spain had money, but the population was insufficient and the resources of soldiers were limited. Although the German region was poor, it had plenty of soldiers. Moreover, the Germans have a martial tradition and have good combat effectiveness. The result of the alliance between the two was that Charles V had beaten France out of the air, forcing France to form an alliance with pagan Turkey in order to distract the HRE.

Had it not been for Charles V's bad luck to coincide with the Reformation Wars and expended a great deal of effort against Protestantism, he might have completely unified the German vassal states.

In fact, the reason for the emergence of the Reformation cannot but mention a wise man - Frederick III, Elector of Saxony, who was the one who calculated Marin.

Frederick III sheltered Martin. Luther, who supported him in the Reformation, was actually trying to muddy the waters of Edland. As long as the German region was in trouble over religious matters, Charles V would not have the energy to clean up the vassal states.

In fact, he did succeed in drawing Germany into a long and bitter war of religion. Moreover, although Frederick III supported Martin Luther, he hid it too well and was not punished.

It's a pity that his successor is not angry, too upright, and exposed. Then, after the defeat of the Wars of Religion, the title of Elector of Saxony fell to George's side, allowing Moritz, the descendant of the stupid George, to take advantage of it, and Saxony was reunited......

In fact, Marin had been hesitant to marry his son Caesar and Princess Anne of the Kingdom of Bohemia. Because, his son and Princess Anne are about the same age.

Moreover, he has a good relationship with the brothers of the Jagiellonian Dynasty. Although his title is a little lower, as long as Prince Sigmunt is used well, it is not impossible to marry Vladislas II of Bohemia.

And if Rajos II had died in battle, as he had done in history, then the kingdoms of Bohemia, Hungary, Silesia, and Moravia would have belonged to his sons......

However, Marin thought about it, and the butterfly effect brought about by his own crossing, Lajos II might not die in battle. In that case, Caesar married Anne of Bohemia for nothing.

Therefore, Marin finally gave up his plan to marry the Kingdom of Bohemia. Because, that one is full of uncertainty. And the marriage with Edward, as long as you can defeat Henry VII, is stable. Because, the French gave Edward's wife Anna birth control pills......

In the case that Edward only had one daughter, Margaret, as long as Edward seized England and married Margaret, it was equivalent to gaining English ......

Which is more cost-effective in the UK or Bohemia, Hungary, etc.? Marin, of course, chose the United Kingdom. Don't look at the Kingdom of Bohemia, the Kingdom of Hungary, plus Silesia and Moravia, which are larger in area and more populous than England. However, Hungary is a pit......

Hungary is located on the border with Ottoman Turkey, and inheriting Hungary is equivalent to inheriting the war with Ottoman Turkey. Charles V's failure to reach Paris had something to do with the fact that Turkey was putting too much pressure on the Hungarian border.

The Balkans have long been a powder keg, a constant war. Moreover, these areas are not close to the sea and cannot develop maritime trade. Therefore, looking at the large territory and large population, it is actually not as affordable as the United Kingdom. After all, Britain is suitable for the development of great navigation, and it is rich in coal and iron, which is much more promising than those four regions......

After much thought, Marin gave up his plan to marry Caesar and Anne of Bohemia. It's a pity that he doesn't have a second legal heir (Robert is an illegitimate child). Otherwise, there must be a way to marry Anne of Bohemia. After all, those four countries were too large, and with Austria, it would become the Austro-Hungarian Empire......
