For these reasons, Rome's relationship with the Javanese Yuan and Ming dynasties was actually quite delicate.

On the one hand, the Khan's court was not satisfied with the restrictive policies of the Ming Dynasty, as this would undoubtedly create obstacles to trade and affect revenues. On the other hand, Javanese Yuan is actually not a good guy either. They are essentially a group of second-class dealers, and they really let these people control the waters of the South Seas, and in the future, they will buy any oriental goods, whether they are resold goods in the Ming Dynasty or spices, silk, and porcelain produced in the South Seas, they will definitely have to increase in price together.

But the Purple Horde was too far from the East, by sea, either to Syria and then to shore; Either to Egypt and then to the Red Sea. In short, there is no way to directly reach the Indian Ocean and participate directly in trade. Later in the reign of Basil Yerigo, the Khan's court began to turn some of its attention to the south, trying to find a breakthrough at sea.

At this time, the Mamluk dynasty of Egypt was mired in frequent civil strife and Timur was rapidly rising in the east.

The decline of the Mamluks was actually expected. Although the country was once militarily strong, its political system was too rough.

During this period, the core of the Mamluk dynasty was the Kipchak slaves. These men were trafficked from the South Russian steppes and carefully selected and trained to become personal soldiers of the Sultan and other officers of all ranks.

Although nominally called a slave, every qualified Mamluk warrior was given a fief, which was actually a kind of knight of the fief. Officers, depending on their rank, were allowed to have different numbers of Mamluks, and the Sultan himself held the most elite and largest branch within the dynasty.

However, the politics of the Mamluk dynasty were very unstable. Whenever a new sultan ascended the throne, the former henchmen and slaves were purged. Of course, these people are not reconciled and will fight back with all their might. More than 100 years later, the Mamluks, who have been suffering from long-term internal friction, no longer have the sharpness they had back then.

The rise of the Purple Horde also inadvertently dealt a blow to the Mamluk dynasty.

During the reign of Alexios Mirgan, the Khanate began to expand eastward along the northern shore of the Black Sea, eventually triggering an all-out war between the Purple Horde and the Green Horde and the White Horde within the Golden Horde. The fragmented Golden Horde could not withstand the Purple Horde's army, and they were either annexed or fled.

No one expected that this achievement would not be a good thing for the Purple Horde. It caused the balance of the armies of the southern and northern armies of the Khanate, which led to the assassination of Alexios, and the first civil war known as the "Civil War".

And they are far more than those affected.

The Mamluk dynasty, in order to maintain its rule, basically did not accept locals at the top, and only recruited Kipchak slave soldiers. However, after the end of the Purple Horde's war against the steppe, the Khan's court worked to restore order, and a large number of steppe people were pacified and co-opted, resulting in a significant reduction in the Kipchak slave trade. As a result, the Kipchak Mamluks, whose status had already begun to waver, were challenged by the Caucasian Mamluks, and the internal instability of the regime became more and more unstable.

At this time, the rise of Timur in the East gave the Purple Horde a better chance.

Timur was originally the small leader of the Western Chagatai Khanate, with few people and little strength, and almost no sense of existence. In the civil war between the Eastern and Western Chagatai Khanates, it was able to rise by relying on the efforts of the left and right.

Although it was called the "Timurid Empire" by some, because of his embarrassing background, Timur did not even have a prestigious title. Since he was not a member of the Golden Family, the Mongol and Turkic tribes of Central Asia did not recognize him as a khan, so Timur could only use the title of emir all year round.

Later, Timur defeated another great warlord, Khusin, and took over the princess of Western Chagatai from him, and since then he has called himself "Gulegan".

This word means "son-in-law" in Mongolian. At that time, Genghis Khan recruited a group of men from other clans through his relatives and incorporated them into his subordinates, so it became one of the titles that had a little bit of contact with the Golden Family. In this way, Gu Liegan became Timur's most famous name, so much so that in the history books of the Ming Dynasty, he was directly called "Timur the horse".

Later, Timur's agent, the White Horde, was lost and turned against the water, relying on the Golden Horde's hometown, and frequently plundered Timur's old nest - the Central Asian River region. In order to solve this scourge, Timur himself led a large army on an expedition, while looking for allies everywhere to contain the lost forces of Tokhtamysh.

It just so happened that the Purple Horde was also at war with the steppe tribes at this time, and the two sides hit it off. Timur set out from the river, went north into the steppe, and marched from east to west; The famous general of the Purple Horde, Taishi Tokhtok Maimaitinicus, led an army from the Crimea and attacked the Don and Volga river valleys in the hinterland of the Golden Horde.

Timur's army was large and in fact a Persianized composite army. Therefore, Tokhtamysh planned to use the traditional tactics of the steppe, to consume them as much as possible during the movement, and then choose the opportunity to attack. However, the crossing of the Sea of Azov by Maimaitinikus's army directly threatened the rear base of Tokhtamysh.

The remaining Golden Horde nobles were unable to break through the Purple Horde camp for a long time, and were even defeated in the counterattack of the other party. This deprived the White Horde army of the strategic space to turn around, lost patience and lost its patience, and was forced to fight a decisive battle with Timur's army in advance, and was finally defeated.

This war allowed the two countries to establish good relations. The Purple Horde discovered the serious lack of legitimacy of Timur's reign - until now, Timur's theoretical legitimacy actually came from his wife of the Western Chagatai and the puppet Khan's father-in-law.

The country is so big, and it is really unreasonable to have a title of son-in-law. So the Purple Horde took the initiative to suggest that there was a wealth of information on its side, and the hometown of the Chagatai Khanate had been war-torn for a long time, and many records may have been lost. They could send professionals to examine Timur's genealogy to see if he was a member of the Golden Family.

A group of scholars set out from Constantinople with great fanfare, and with the cooperation of the Timurid regime, they made a propaganda all the way to Samarkand.

The old scholars brought a lot of archives of the Golden Horde, which is said to be the Batu era, and after some research according to the local documents in Central Asia, it turned out that Timur's family was also a member of the Golden Family that had been lost for many years. In terms of seniority, he is still the uncle of Purple Horde. Therefore, everyone immediately persuaded him to come in and suggested that the imperial uncle of Timur sit on felt and call Khan in order to correct his name. The Timurid regime finally became the "Timurid Khanate" in name only.

Timur was very interested in this, and sent a large amount of gold and silver treasures to the purple horde as a thank you gift, and also sent his fourth son Shaharu to lead a return visit. However, it was not long before the two sides enjoyed victory before news came that Tokhtamysh had made a comeback.

Tokhtamysh was also a generation of heroes, quite prestigious in the steppe, and after the defeat, he still had many followers, and soon drove out the puppet nobles supported by Timur, and reoccupied the old capital of the Golden Horde, Belgosare.

Tokhtamysh also learned his lesson this time and learned from the experience of the enemy's victory. He sent people to contact the Ottomans, the overlord of Asia Minor, and the Mamluk dynasty entrenched in Egypt, to unite and make trouble for Timur.

Timur was forced to contact the Purple Horde again to send troops, preparing to preemptively deal with the culprit Tokhtamysh, and then transfer the army south to sweep away the other enemies.
