After the conquest in Asia, the Ottoman country turned to Europe. The Ottoman state wanted to conquer the head of Christian Europe. To abolish Christianity in order for Christians to become Muslims. The Ottoman state set out to conquer Europe. The first countries to be attacked were actually Serbian lands.
A great empire that was one of the strongest in Europe while the Serbian empire was. That empire was divided into smaller territories, so each of these new territories was weaker individually than if they were all in one state. It was a great chance for the Ottoman state to embark on a campaign in Europe.
The Ottoman state used that chance. The Ottoman army was too strong, that army could easily conquer most of Europe very quickly. All European countries relied on the Serbian army, which was the only one that could stop the Ottoman army.
Prince Lazar Hrebeljanovic was the master of the strongest territory of the other territories of the Serbian Empire, which was divided into smaller states. Lazar knew that only a united Serbian army could stop the Ottoman superpower. That is why Lazar sent his couriers to other small territories, in order for the Serbian army to be reunited.
The Ottoman Sultan Murat sent an ultimatum to the Serbian prince Lazar, to surrender or Murat would conquer all Serbian territories. Lazar refused that ultimatum because he believed that the Serbian army was strong enough to stop, at least for a short time, the Ottoman conquest of Europe.
Sultan Murat gathered all his army and set out to face the Serbian prince Lazar. Lazar knew that, so he set out to gather the entire Serbian army. Vuk Brankovic also joined him in that, he was the master of the territory where the fight was supposed to take place. Lazar was joined by the Bosnian king Tvrtko, who sent only a part of his army, that part of the army was led by Duke Vlatko Vukovic.
The Serbian army went to meet the Ottoman army led by Sultan Murat with his sons Jagub and Bajazit. Both armies arrived on the field of Kosovo, and it was agreed that all armies would clash. The fight took place on June 28, 1389. The coincidence is that it is the date of the great Christian holiday "Vidovdan". It was on that holiday that the Serbian army set out to defend the head of Europe from the Ottomans.
The exact number of soldiers on both sides is unknown. But it is known that the Ottoman army had twice as many soldiers as the Serbian army. The Serbian army is divided into three groups. Croesus Lazarus was in the central group and led that group. On the left was a group led by Vuk Brankovic, while on the right was a part of the army led by Duke Vlatko Vukovic.
On the other hand, the Ottoman army was divided into three groups. Their central group was led by Murat himself, while the left group was led by his son Jakub, and the right group by his son Bajazit.
In Lazar's part of the army, there was also one of Lazar's best knights named Miloš Obilić, Miloš gathered a dozen of his fellow soldiers, the night before the battle, Miloš and his friends agreed that Miloš would kill Sultan Murat.
In the early morning hours of June 28, 1389, the battle began. At that moment, the whole of Europe prayed to God that the Serbian army would win and stop the further penetration of the Ottoman army into Europe.
After several hours of fighting, the Serbian army was seen pushing the Ottoman army back. But the Ottoman soldiers soon gathered and launched a fierce counterattack. The Ottoman army also received reinforcements. Seeing that, Milos decided that it was the right time to go with his comrades to the sultan himself to kill him. They came to the sultan, Milos pretended to surrender, surrendered his weapons and went to the sultan to kiss his boot. So he approached Murat, then Milos took out a hidden knife and killed Murat. Shortly afterwards, Murat's guards killed Miloš.
After the death of the sultan, a commotion began in the Ottoman army, there was no one to command the army. Murat's son Bajazit saw that and set out with his group of soldiers to retreat, he let his brother Jakub fight alone. Jacob was killed while Bayezid fled.
The Serbian army won with far fewer casualties than the Ottoman army, which had many more soldiers at the very beginning of the battle. Vuk Brankovic returned to his capital, and so did Vlatko Vukovic, who headed back to Bosnia. Prince Lazar remained on that battlefield because the Church was not far away, where he wanted to pray to her and thank God for the incredible victory.
All of Europe celebrated the victory of the Serbs, and bells rang in all cathedrals in honor of Serbian heroes. But this story is not over yet ... Bayazit, who escaped, sent his army back for the bodies of his father Murat and for his brother Jakub, in order to take them away and bury them. Bayazit's army, in search of Murat and Jakub, came across the church where Prince Lazar was praying. Bayezid's army broke into the church and killed Lazar, who did not have a weapon with him.
After that, the Serbian Church proclaimed Lazar a saint, as well as a martyr who managed to stop an army twice as strong as the one he had.
