Siege of Vienna (1529) in the context of "Archduchy of Austria"

Suleiman I (Ottoman Turkish: سلیمان اول, romanized: Süleymân-ı Evvel; Modern Turkish: I. Süleyman, IPA: [biɾinˈdʒi sylejˈman]; 6 November 1494 – 6 September 1566), commonly known as Suleiman the Magnificent in the Western world and as Suleiman the Lawgiver (قانونی سلطان سلیمان, Ḳânûnî Sulṭân Süleymân) in his own realm, was the Ottoman sultan between 1520 and his death in 1566. Under his administration, the Ottoman Empire ruled over at least 25 million people.

After succeeding his father Selim I on 30 September 1520, Suleiman began his reign by launching military campaigns against the Christian powers of Central and Eastern Europe and the Mediterranean; Belgrade fell to him in 1521 and Rhodes in 1522–1523, and at Mohács in 1526, Suleiman broke the strength of the Kingdom of Hungary. Hungary was subsequently divided, with much of it incorporated directly into the empire. However, his defeat at the siege of Vienna in 1529 checked advances further into Europe.

Pavle Bakić (Serbian Cyrillic: Павле Бакић, Hungarian: Bakics Pál; c. 1484 – 9 October 1537) was the last titular Despot of Serbia. He was one of the most notable military commanders among Serbian nobility in the Kingdom of Hungary, and fought against the Ottoman Empire in several battles, most notably at the Battle of Mohács (1526) and the Battle of Vienna (1529). He fell at the Battle of Gorjani (1537).

Nicholas, Count of Salm (1459 – Salmhof, Marchegg, Lower Austria, 4 May 1530) was a German soldier and an Imperial senior military commander (German: Feldherr). His greatest achievement was the defence of Vienna during the first siege by the Ottoman Empire in 1529.

The Landsknechte (singular: Landsknecht, pronounced [ˈlantsknɛçt]), also rendered as Landsknechts or Lansquenets, were German mercenaries used in pike and shot formations during the early modern period. Consisting predominantly of pikemen and supporting foot soldiers, their front line was formed by Doppelsöldner ("double-pay men") renowned for their use of Zweihänder and arquebus. They formed the bulk of the Holy Roman Empire's Imperial Army from the late 15th century to the early 17th century, fighting in the Habsburg-Valois wars, the Habsburg-Ottoman wars, and the European wars of religion.

Although prone to mutiny if unpaid and divided within their ranks between Catholics and Lutherans, the Landsknechte were well-armed and experienced warriors, recruitable in large numbers throughout Germany and Austria by the Holy Roman Emperor. This guaranteed both quantity and quality to the Imperial military for a century and a half. At their peak during the reign of Charles V of Habsburg, and under the leadership of notable captains such as Georg von Frundsberg and Nicholas of Salm, the Imperial Landsknechts obtained important successes such as the capture of the French King Francis I at the Battle of Pavia in 1525 and the resistance against the Ottoman Turks led by Suleiman the Magnificent at the Siege of Vienna in 1529, while also being responsible for the Sack of Rome in 1527.

The Augsburg Confession (German: Augsburger Bekenntnis), also known as the Augustan Confession or the Augustana from its Latin name, Confessio Augustana, is the primary confession of faith of the Lutheran Church and one of the most important documents of the Protestant Reformation. The Augsburg Confession was written in both German and Latin and was presented by a number of German rulers and free-cities at the Diet of Augsburg on 25 June 1530.

The Holy Roman Emperor, Charles V, had called on the Princes and Free Territories in Germany to explain their religious convictions in an attempt to restore religious and political unity in the Holy Roman Empire and rally support against the Ottoman invasion in the 16th-century Siege of Vienna. It is the fourth document contained in the Lutheran Book of Concord.

The Battle of Alexander at Issus (German: Alexanderschlacht) is a 1529 oil painting by the German artist Albrecht Altdorfer (c. 1480–1538), a pioneer of landscape art and a founding member of the Danube school. The painting portrays the 333 BC Battle of Issus, in which Alexander the Great secured a decisive victory over Darius III of Persia and gained crucial leverage in his campaign against the Persian Empire. The painting is widely regarded as Altdorfer's masterpiece, and is one of the most famous examples of the type of Renaissance landscape painting known as the world landscape, which here reaches an unprecedented grandeur.

Duke William IV of Bavaria commissioned The Battle of Alexander at Issus in 1528 as part of a set of historical pieces that was to hang in his Munich residence. Modern commentators suggest that the painting, through its abundant use of anachronism, was intended to liken Alexander's heroic victory at Issus to the contemporary European conflict with the Ottoman Empire. In particular, the defeat of Suleiman the Magnificent at the siege of Vienna may have been an inspiration for Altdorfer. A religious undercurrent is detectable, especially in the extraordinary sky; this was probably inspired by the prophecies of Daniel and contemporary concern within the Church about an impending apocalypse. The Battle of Alexander at Issus and four others that were part of William's initial set are in the Alte Pinakothek art museum in Munich.
