Buda in the context of "Esztergom"

The siege of Vienna, in 1529, was the first attempt by the Ottoman Empire to capture the city of Vienna in the Archduchy of Austria, part of the Holy Roman Empire. Suleiman the Magnificent, sultan of the Ottomans, attacked the city with over 100,000 men, while the defenders, led by Niklas Graf Salm, numbered no more than 21,000. Nevertheless, Vienna was able to survive the siege, which ultimately lasted just over two weeks, from 27 September to 15 October 1529.

The siege came in the aftermath of the 1526 Battle of Mohács, which had resulted in the death of Louis II, King of Hungary, and the descent of the kingdom into civil war. Following Louis' death, rival factions within Hungary selected two successors: Archduke Ferdinand I of Austria, supported by the House of Habsburg, and John Zápolya. Zápolya would eventually seek aid from, and become a vassal of the Ottoman Empire, after Ferdinand began to take control of western Hungary, including the city of Buda.

Jadwiga (Polish: [jadˈviɡa] ; 1373 or 1374 – 17 July 1399), also known as Hedwig (from German, Hungarian: Hedvig), was the first female monarch of the Kingdom of Poland, as well its last hereditary ruler. She reigned from 16 October 1384 until her death. Born in Buda, she was the youngest daughter of Louis I of Hungary and Poland, and his wife, Elizabeth of Bosnia. Jadwiga was a member of the Capetian House of Anjou, and had forebears among the Polish Piasts.

In 1375, it was planned that when becoming old enough, Jadwiga would marry William of Austria and she lived in Vienna from 1378 to 1380. Louis I is often thought to have regarded her and William as his favoured successors in Hungary after the 1378 death of her eldest sister, Catherine, since the following year the Polish nobility had pledged their homage to Louis' second daughter, Mary, and Mary's fiancé, Sigismund of Luxembourg. However, Louis died, and in 1382, at her mother's insistence, Mary was crowned "King of Hungary". Sigismund of Luxembourg tried to take control of Poland, but the Polish nobility countered that they would be obedient to a daughter of Louis only if she settled in Poland. Queen Elizabeth then chose Jadwiga to reign in Poland but did not send her to Kraków to be crowned. During the interregnum, Siemowit IV, Duke of Masovia, became a candidate for the Polish throne. The nobility of Greater Poland favoured him and proposed that he marry Jadwiga. However, Lesser Poland's nobility opposed him, and they persuaded Elizabeth to send Jadwiga to Poland.

The Austro-Hungarian Compromise of 1867 (German: Ausgleich, Hungarian: Kiegyezés) established the dual monarchy of Austria-Hungary, which was a military and diplomatic alliance of two sovereign states. The Compromise only partially re-established the former pre-1848 sovereignty and status of the Kingdom of Hungary, being separate from, and no longer subject to, the Austrian Empire. The compromise put an end to the 18-year-long military dictatorship and absolutist rule over Hungary which Emperor Franz Joseph had instituted after the Hungarian Revolution of 1848. The territorial integrity of the Kingdom of Hungary was restored. The agreement also restored the old historic constitution of the Kingdom of Hungary.

Hungarian political leaders had two main goals during the negotiations. One was to regain the traditional status (both legal and political) of the Hungarian state, which had been lost after the Hungarian Revolution of 1848. The other was to restore the series of reform laws (the so-called April Laws) of the revolutionary parliament of 1848, which were based on the 12 points that established modern civil and political rights and economic and societal reforms in Hungary. The April Laws of the Hungarian revolutionary parliament (with the exception of the laws based on the 9th and 10th points) were restored by Franz Joseph.

John Sigismund Zápolya or Szapolyai (Hungarian: Szapolyai János Zsigmond; 7 July 1540 – 14 March 1571) was King of Hungary as John II from 1540 to 1551 and from 1556 to 1570, and the first Prince of Transylvania, from 1570 to his death. He was the only son of John I, King of Hungary, and Isabella of Poland. John I ruled parts of the Kingdom of Hungary with the support of the Ottoman Sultan Suleiman; the remaining areas were ruled by Ferdinand I of Habsburg, who also ruled Austria and Bohemia. The two kings concluded a peace treaty in 1538 acknowledging Ferdinand's right to reunite Hungary after John I's death, though shortly after John Sigismund's birth, and on his deathbed, John I bequeathed his realm to his son. The late king's staunchest supporters elected the infant John Sigismund king, but he was not crowned with the Holy Crown of Hungary.

Suleiman invaded Hungary under the pretext of protecting John Sigismund from Ferdinand. Buda, the capital of Hungary, fell to the Ottomans without opposition in 1541, but Suleiman allowed the dowager queen, Isabella, to retain the territory east of the river Tisza on John Sigismund's behalf. Isabella and John Sigismund moved to Lippa (now Lipova in Romania). Before long, they took up residence in Gyulafehérvár in Transylvania (Alba Iulia in Romania). John Sigismund's realm was administered by his father's treasurer, George Martinuzzi, who sought to reunite Hungary under the rule of Ferdinand. Martinuzzi forced Isabella to renounce her son's realm in exchange for two Silesian duchies and 140,000 florins in 1551. John Sigismund and his mother settled in Poland, but she continued to negotiate for John Sigismund's restoration with Ferdinand's enemies.

Line 1 (Officially: Millennium Underground Railway, Metro 1 or M1) is the oldest line of the Budapest Metro, built from 1894 to 1896. It is known locally as "the small underground" ("a kisföldalatti"), while the M2, M3 and M4 are called "metró". It was the first electrified underground on the European mainland, and the world's second oldest electrified underground after the London Underground. It was finished by April 1896 and was inaugurated by the emperor of Austria-Hungary, Franz Joseph on 3 May 1896.

Line 1 runs northeast from the city center on the Pest side under Andrássy út to the Városliget, or City Park. Like Line 3, it does not serve Buda. Its daily ridership is estimated at 80,000.

Budin Eyalet (also known as Province of Budin/Buda or Pashalik of Budin/Buda, Ottoman Turkish: ایالت بودین, romanized: Eyālet-i Budin) was an administrative territorial entity of the Ottoman Empire in Central Europe and the Balkans. It was formed on the territories that Ottoman Empire conquered from the medieval Kingdom of Hungary and Serbian Despotate. The capital of the Budin Province was Budin (Hungarian: Buda).

Population of the province was ethnically and religiously diverse and included Hungarians, Croats, Serbs, Slovaks, Muslims of various ethnic origins (living mainly in the cities) and others (Jews, Romani, etc.). The city of Buda itself became majority Muslim during the seventeenth century, largely through the immigration of Balkan Muslims.

The siege of Buda (4 May – 21 August 1541) ended with the capture of the city of Buda, the historical capital of the Kingdom of Hungary, by the Ottoman Empire, leading to about 150 years of Ottoman rule in parts of Hungary. The siege, part of the Little War in Hungary, was one of the most important Ottoman victories over the Habsburg monarchy during Ottoman–Habsburg wars (16th to 18th century) in Hungary and the Balkans.

Hans Krell (c. 1490 – 1565 or 1586), also Krehl ou Kreil, was a German painter of the Renaissance, mainly known as a portrait painter. He is thought to have been born in Crailsheim or Ansbach, and died in Leipzig.

Hans Krell started his career as court painter of George the Pious, Margrave of Brandenburg-Ansbach in Ansbach. He then entered into the service of King Louis II of Hungary in Prague and Buda, where he was employed as court portraitist in the years 1522–1526. He is later recorded in Leipzig (from 1531) and in Freiberg in Saxony (since 1534). Krell was known as the Fürstenmaler (Painter of Princes) in service of the German Princes – Albrecht of Brandenburg-Ansbach, Duke in Prussia, Hedwig Jagiellon, Electress of Brandenburg and the Elector Augustus of Saxony. His paintings of Saxon princes in the ceremonial hall and the council chamber of the Old Town Hall in Leipzig were continually being completed.
