Siege of Vienna
And high treason

The Australian terrorist wrote on the gun that killed 49 unarmed Muslims in the mosque was Vienna 1683, and of course 90% of Muslims who read these words did not know what they mean, so let's read the topic of Vienna 1683 and why this Australian terrorist wrote it on his gun.

The Battle of Vienna took place on 20 Ramadan 1094 AH / 12 September 1683 AD, and after the Ottoman Empire besieged Vienna for two months, the battle broke the primacy of the Ottoman Empire in Europe, where the Polish, German and Austrian forces led by King John III Sobieski of Poland won the battle against the Ottoman army led by Grand Vizier Kara Mustafa, commander of the Ottoman forces.

Ottomans and Vienna
The conquest of Vienna was a long-held dream of the Ottoman sultans because of its strategic importance in controlling the trade and communication lines in the European heartland. Each time, the Ottomans were content to return from the walls of Vienna with money and perhaps new parts of Eastern or Central Europe under agreements with the Austrian Empire.
The first siege was in the time of Suleiman the Magnificent a century and a half earlier, after he penetrated into Europe after defeating the Hungarians in the terrible Battle of Mohács, and the armies of the Magnificent entered the capital of Hungary, Budapest, on 3 Dhul Hijjah 932 AH / 10 September 1526 AD, making (Hungary) another Ottoman state and establishing the absolute control of the Ottomans in central and eastern Europe.
In 1683 AD, the Turks besieged Vienna for the second time, but Graf Staremberg was able to repel the Turks in a battle on Mount Kallenberg, after which they recovered Budapest from the Ottoman Empire in 1686 AD after 145 years of Ottoman control over Budapest.

Before the battle
Germany was competing with the Ottomans in the regions of Hungary and Slovakia, and the idea of dealing a strong blow to Germany to stop it from interfering in the affairs of Hungary dominated the Ottoman Grand Vizier. Qara Mustafa Pasha was able to convince the Ottoman Sultan Mehmed IV and the Himayuni Diwan (Council of Ministers) to declare war on Germany. Grand Vizier Ahmed Pasha Kobrilli moved from Edirne, arrived in Hungary at the head of a large army, about one hundred and twenty thousand soldiers, equipped with guns and ammunition loaded on sixty thousand camels and ten thousand mules, and entered Slovakia Slovakia, beating all the military fortifications that were in his way, heading to the castle of Nohzel, which is located northwest of Budapest, about 110 km east of Vienna and about 80 km east of Bratislavia, which was fortified by the Germans, and made it very strong to become the strongest castles in Europe, and the Ottoman army began its siege on 13 Muharram 1074 AH / 17 August 1663 AD, and the Ottoman army began to besiege it on 13 Muharram 1074 AH / 17 August 1663 AD.
The Ottoman siege of the castle lasted 37 days, forcing the commander of the castle's garrison to request surrender, and the Grand Sadr agreed to this on the condition that the garrison evacuate the castle without weapons or ammunition. This campaign caused a tremendous rumble in Europe, and struck fear and panic in the hearts of its kings in general.
As a result of this great conquest, Ahmet Kobrilli advanced with his armies and conquered the provinces of Moravia (in Czechoslovakia) and Silesia in the centre of Europe.

War Council
Grand Vizier Kara Mustafa Pasha gathered his army's war council and announced that he would seize Vienna, and that he would dictate his terms to Germany in this city; because the seizure of Yang Qala, the key to Vienna, located 80 km east of Vienna on the west bank of the Rab River, could not subdue Germany and make it give up its hand in Hungary's affairs.
The decision of Kara Mustafa Pasha caused confusion and debate among the ministers. Minister Ibrahim Pasha objected to it, saying that Sultan Mehmed IV's desire was to capture Yang Qala and skirmish in Central Europe with the Ottoman thunderbolt battalions, and that the campaign against Vienna would probably be next year. He replied that it was difficult for an army to gather again with such density and strength, and that it was necessary to inflict a strong and fatal blow on the Germans, otherwise the war would be prolonged, especially since Germany had made peace with France and was safe on the western side. Especially since Germany made peace with France and became safe from the western side, and Emperor Leopold agreed with the Polish King Sobieski to restore the region of Badoglia, and Venice must be included in this agreement, and thus Russia and the rest of the European countries will join this Christian alliance alongside Germany, and this requires breaking it and shattering this newborn alliance in that year, otherwise the war will be prolonged for an unknown period of time.

Europe's position
The Pope of Rome declared a crusade against the Ottomans, ordered King Sobieski of Poland to break his covenant with the Ottomans, and also ordered the German princes of Saxony and Bavaria, the closest princes of Europe, to head to Vienna as soon as possible, so the European armies from Poland, Germany and Austria gathered until their number reached 70,000,The Duke of Lorraine left the general command to King John III Sobieski of Poland, and their preparations were completed on Friday, 11 September, after they felt that the fall of Vienna was only a few days away; therefore, the Europeans crossed the Ottoman-controlled Dona Bridge by force, no matter the cost in losses, as it was not possible to deliver supplies to Vienna without crossing this bridge.

Betrayal
Qara Mustafa had placed a large Ottoman force led by Murad Krai, the Crimean governor, at the Dona Bridge, the only road leading to Vienna from the west, to prevent the advance of the Europeans, and Murad Krai was ordered to blow up the bridge if necessary.
Murad Krai committed a great betrayal of Islam and Muslims by allowing the Europeans to cross the bridge without a fight, because of his hatred and enmity towards Mustafa Pasha, Mustafa Pasha hated Murad Krai and treated him badly, while Murad believed that Mustafa Pasha's failure in Vienna would bring him down from power and the position of leadership, and it did not occur to this traitorous commander that the Ottoman loss before Vienna would change the course of world history, so Murad decided to remain a spectator of the European forces crossing the Douna Bridge to break the siege imposed on Vienna, without moving a finger. In addition, there were ministers and bekwats in the Ottoman army who did not want Kara Mustafa Pasha to be the conqueror of Vienna, before which Sultan Suleiman the Magnificent failed.

Armageddon
On Saturday, 20 Ramadan 1094 AH / 12 September 1683 AD, the two armies met in front of the walls of Vienna. The Europeans were rejoicing that they had crossed the Dona Bridge without spilling a single drop of blood, and the Ottoman army was in a state of shock seeing the Europeans in front of them after crossing the Dona Bridge, but Mustafa Pasha launched a counter-attack, with most of his troops, and parts of the Janissary elite to conquer the city. The Turkish commanders had intended to occupy Vienna before the arrival of John III Sobieski, but time ran out, as military engineers prepared another large and final explosion to provide access to the city, While the Turks hastily finished their work and closed the tunnel to make the explosion more effective, the Austrians discovered the cave in the afternoon, and one of them entered the tunnel and defused the explosion just in time.
Another great betrayal occurred on the part of Oğlu Ibrahim, commander of the right flank of the Ottoman army, as he withdrew from the fighting, and this withdrawal had the greatest impact on the defeat of the Ottomans. Qara Mustafa was able to withdraw in an orderly manner from the battlefield, and on the way back Qara Mustafa executed both Murad Krai and Oğlu Ibrahim, but this did not help him with Sultan Mehmet IV, who ordered him to be killed.
The Ottomans lost 15,000 men in the fighting, the Europeans lost nearly 4,000, the Ottoman army took 81,000 prisoners during the retreat, and the 59-day siege ended.

Results of the battle
The defeat of the Ottomans at the walls of Vienna was a turning point in Ottoman and European history. With its defeat at Vienna, the Ottoman state lost the dynamic of attack and expansion in Europe, and the defeat was a stopping point in the history of the Ottoman state. The armies of the Christian Coalition then moved to carve out parts of the Ottoman possessions in Europe over the following centuries.
