Bayeset I (approximately 1354-1403) was the Sultan of the Ottoman Empire, ruling from 1389 to 1402. He was the son of Murad I and a famous military commander, also known as "Lightning"; In 1389, he participated in the Battle of Kosovo with his father. After his father's assassination, he continued to lead the army in combat, annihilating the coalition forces of Serbia, Bulgaria and other countries, capturing and killing his commander, Duke Lazar, and conquering Serbia and Bulgaria. In 1395, Bayeset led his army to invade Hungary again. In 1396, he fought against the Hungarian and Polish armies commanded by King Sigismund of Hungary, as well as a crusade of 100000 British and French knights in Nicoburg, and achieved a complete victory. In this battle, he captured more than 10000 knights. Just as Bayette was preparing to continue his westward invasion of Europe, the powerful army of Timur from the East invaded Asia Minor, and Bayette led his army to the east. The Timur army had 140000 people, and Bayeset had 85000 people. The two sides engaged in a decisive battle in Ankara in 1402. Bayeset was defeated and captured, and later died in prison. Although Bayeset I was in a precarious state, he achieved numerous victories in major battles throughout his life and can also be called a famous general.

When his father, King Murad I, was still a prince, he met an irresistible Greek beauty. This beautiful woman, Gulchichek, who was selected from the female slaves in the prisoner of war camp and later honored as the "Night Rose", became his wife. In 1354, their descendant Bayeset was born. In 1381, this mixed race child was sent to Asia Minor as governor, and he had to digest the newly annexed territory for the empire. His work was so successful that his father assigned him a new and arduous task: to eliminate the powerful enemy country, the former suzerain, Karaman. In 1386, the two countries fought a decisive battle, and the young Prince Charming completely defeated Karaman and demoted his opponent to a vassal state. On the battlefield, he won the infamous reputation of "Thor's Hammer" for his brave and not reckless performance.

In the palace, he not only handled government affairs in an orderly manner but also invited famous writers for discussions. From then on, he became fascinated by the mystical study of the Sophian doctrine, until one day he married his beloved daughter, the water lotus Nilufer, to the head of the Sophian order.

Battle of Kosovo
In 1389, King Rajos II of Hungary, who had allied with Austria, rejected the Ottoman Empire's peace initiative and the first Kosovo Campaign, which determined the fate of the Balkans, erupted. His father Murad I was assassinated at the beginning of the campaign, and Bayeset was forced to ascend to the throne in the military due to his father's tragic death. He had to face what appeared to be an extremely unfavorable and rapidly changing situation, and was forced to make both genius and non genius decisions. At present, the fate of the nation, empire, and even history has suddenly shifted to his hands, and this young man's magnificent and outstanding explosive appearance has shaken the entire historical stage. The divided Balkans will never be the same again!
The young Bayeset Sultan quickly sorted out his retreating warriors, and this new leader deeply knew that his people never lacked courage and wisdom. They were just messed up because of the sudden death of their beloved Sultan. In the midst of the most intense battle, the coalition suddenly discovered that their opponents had regained their formation, and their fear and sadness had turned into burning anger. The Ottoman army, under the command of the new Sultan, had turned the initial failure into the beginning of a new conspiracy. The light cavalry, who came and went like a wind, began to consciously divide the alliances of different races. The coordination and unity among the various departments of the coalition began to be disrupted, and chaos spread everywhere. The victory at the beginning also tied the hands and feet of the coalition forces. Their continuous heavy cavalry assault began to lose cohesion, and the attack gradually declined. The huge number advantage of the Ottoman army also ensured the smooth implementation of the plot. Türkiye cavalry began to gather on the flank, and then accelerated with a huge arc... The cavalry assault that decided the victory began!
The horseshoe storm carried the lightning of death towards the flank of the coalition forces. The twisted battlefield began to envelop the still valiant coalition forces, some races began to waver, some races began to retreat, and some troops began to flee and scatter. By mid afternoon, the center of the coalition forces was completely packed into their pockets, and there was no doubt of victory or defeat. The Serbs at the center of the front line, led by their brave leader Duke Lazar, still bravely marched forward despite their backs. These resilient warriors fought tirelessly with infinite affection for the holy land of their nation, Kosovo, while some knights in the coalition, who sacrificed their lives for freedom and honor, still launched a desperate charge against the dense Ottoman infantry. After adjusting the positions of each unit, Bayeset tightened the noose of the encirclement, and the battle eventually evolved into a massacre

Bayeset, who harbored the grudge of killing his father, issued a death order against the Serbian army. The flowers of the prominent Serbian nobility all withered in this battle, and the corpses of Serbian soldiers covered every corner of the battlefield. Blood stained the small river red... Afterwards, a large number of folk legends emerged around the Battle of Thrushcross, with folk artists singing the heroic deeds and tragic destinies of Serbian ancestors through the streets and alleys accompanied by the gusri qin. The organized resistance of various ethnic groups in the Balkan Peninsula comes to an end. Young Bayette walked from behind the scenes to the front desk and began his solo dance.
Serbia lost almost everything in the disastrous defeat in Kosovo, losing its land, people, autonomy, dignity, soldiers, lords, and the glorious kingdom and their beloved leader - the King Lassar, who did not claim to be king. Amidst a state of desolation, life continued, and Lazar's widow Marika was hastily elected as regent of the kingdom, while her son, 15-year-old Stephen Lazavich, ascended to the throne with tears in his eyes. When the remnants of the Serbian army were preparing to defend the border, the new king's edict was issued: the eldest daughter Maria married the Ottoman Empire in Sultan Bayeset, and Serbia would pledge allegiance to the Ottoman Empire while maintaining autonomy. Since then, Lazavic and Bayeset became like-minded comrades until their downfall in the Battle of Ankara.
Battle of Nicopolis
In 1391, Bayette led his army to besiege the capital of the Byzantine Empire, Constantinople. At the request of Byzantine Emperor John V, a new crusade was summoned and organized. The Holy Roman Emperor and King Sigismund of Hungary, after receiving assistance from the Western crusades, launched the Second Battle of Bulgaria in 1396. The Western Allied Forces crossed the Danube River, captured Widdin and Rahova, killed all the garrisoned Türkiye troops, and then marched towards Nicoburg, the largest city in Central Bulgaria. Then the slow pace of the Western coalition forces allowed the Turks enough time to respond. Bayeset ordered his troops stationed in Europe not to launch attacks without authorization until the arrival of the main force in Asia. He himself summoned the Asian army to cross the Dardanelles Strait and ultimately assembled all his forces in the military stronghold of Andreana. Then Bayeset led the army to approach Nicofort by force. When Sigismond's scout cavalry found the Turks, they were less than a day away from Nicofort.

After arriving at Nicoburg, Bayeset chose a defensive stance. He was very familiar with the terrain and chose a highland 4 miles south of Fort Nico, with valleys on both sides of the position that could hide the reserve forces. Bazizad set up three lines of defense in front of the main force: the first line was composed of miscellaneous light archers, and behind the archers were a large number of pointed wooden stakes, while behind the stakes were a large number of miscellaneous light infantry archers. Behind the defensive line were the main feudal cavalry of the Ottomans. And the Sipashi cavalry and the Serbian heavy cavalry are respectively hidden on the wings of the main cavalry as reserve teams. Bazizad's plan was to use the miscellaneous armies in front as bait to lure Western coalition cavalry to attack. When the opponent suffered losses in the melee and their order became chaotic, he would then use his main cavalry, who were on high alert, to launch a counterattack from three directions to determine the victory.
The Battle of Nicoburg came to an end in just one day, and the powerful main force of the Hungarian army dissipated after the war. The victory of the Ottoman side can be said to be reasonable. Bayeset demonstrated excellent command ability. Set up the battlefield, carefully set up three lines of defense in front of the main formation, and deploy two ambushes on the flank, all showing their cunning and cunning. It has been proven that although the combat effectiveness of French knights may have exceeded Bayette's expectations, it was ultimately the two ambushes that decided the outcome of the battle twice. As for the Western coalition, it was lackluster, and Sigismund's initial plan was also considered good, but it was not realized due to internal conflicts. Throughout the entire campaign, the Christian army only engaged in frontal attacks, and coupled with internal turmoil before the battle, failure was inevitable. The Battle of Nicolberg was the first act of the century long Türkiye Hungary War, and could have been the last act. Because the essence of the Hungarian army was almost completely destroyed in Nicoburg. If it were not for Bayeset's exceptional interest in Asian affairs, the prospects for Hungary and even the entire Christian Eastern Europe would be very bleak. However, Bayeset seemed more concerned with the Seljuk Turkic chieftains who conquered Asia Minor. And his eastward expansion ultimately brought disaster to himself.
On the second day after the end of the battle, as revenge for the Western coalition's massacre of Rahova and other Ottoman prisoners of war, Bayset ordered all prisoners to be killed, leaving only John of Burgundy and a small number of prominent nobles to exchange for ransom. Thousands of people were beheaded in front of these senior prisoners of war, who were forced to watch this bloody scene. After about 10000 people were slaughtered, Bayeset changed his mind and ordered the remaining numerous survivors to be sold as slaves. Bayeset built his beautiful new capital in Bursa to celebrate this victory.

After winning the Battle of Nicoburg, John Hilterberg, who later became a famous traveler, joined the command of Suleiman, the son of Bayeset, and became a warrior of the Ottoman Empire.
The siege of Constantinople continued until 1401. For a period of time, Byzantine emperors even had to flee Constantinople. But fortunately, the Mongols saved the Byzantine Empire. Because in 1402, the Battle of Ankara broke out.
Battle of Ancyra
Bayeset's expansion in the East angered the even stronger Timurid Empire, as the former sheltered the latter's enemies and invaded its sphere of influence in Armenia. In the spring of 1402, Timur mobilized about 80000 troops to attack the Türkiye Empire, including musketeers and war elephants. The main assault force was cavalry. The next several cities are near Ankara, the capital of Türkiye. He encountered a 70000 strong army of Bayeset on standby.
On July 28, 1402, the Battle of Ankara officially began. Timur saw that the Türkiye Army had occupied the land. Although he had the advantage in military strength, he was not sure to go straight to the pocket. He is not a Western knight who can only fight head-on, so he decided to use higher mobility than Türkiye's army to bypass the Turkish army's defense line and turn its back from the south to lure the Turkish army to the plain for a decisive battle. His army simply ignored Türkiye's army and left. This surprised Bayeset and he immediately left camp to closely track him. Timur proudly played a trick, retreated slightly, set up a defense line and waited for the arrival of Türkiye's main force.
Bayeset's army rushed to the Ankara battlefield through forced force, but before they could rest, they hastily engaged in battle, concentrating all 70000 people in the center and launching an attack on the Timur army. The heavy cavalry on both wings of the Timur army came crashing in waves, continuously attacking the flank of the Turkish army, crushing the left wing of the Turkish army and beginning to encircle in a roundabout manner. For a moment, iron cavalry fluttered on the battlefield, roaring like thunder. The smoke of firearms fired from both sides ignited, and two countries, both skilled in cavalry, personally commanded by their respective monarchs, engaged in a decisive battle!

In the face of Timur's relentless pressure on the cavalry, nearly 20000 people of the Tatar army guarding the right wing of the Turkish army were called down and mutinied by his old masters under Timur's tent. Later, nearly 20000 people of Anatolia troops and some of Türkiye's pro guards refused to surrender. The morale of the Turkish army plummeted, and nearly 40000 troops were lost at a time. They had to rely on 30000 troops to resist Timur's forces of more than 100000. The geographical advantage was lost, and there was no chance of victory. Finally, the Turkish army collapsed for thousands of miles. At dusk, Sultan Bayeset was captured, and the thunder god's war drums rang out.
Timur just wanted to restore his vassal territory, and did not weaken the Ottoman Empire too much. He distributed the old territory of Türkiye equally to the four sons of Baysett, as for Baysett himself. Some reports at the time pointed out that Timur detained Bayeset in prison as a trophy of war. Similarly, there are many stories about Bayeset's imprisonment, including one that describes Timur using Bayeset as a footstool, and another article that further describes Timur asking Bayeset's Serbian wife to dance naked in front of his courtiers. However, these records are considered untrue. Timur's courtiers wrote that Bayezid received excellent care, and he even mourned Bayezid's death. Similarly, the history of Timur and other rulers also proves that Timur kept his promise, stating that he would work to restore Bayezid to the Ottoman throne. In 1403, Bayezid passed away, and some literature suggests that Bayezid committed suicide by ramming into an iron rod in a cage.
