The Eurovision Song Contest 2004 was the 49th edition of the Eurovision Song Contest. It took place in Istanbul, Turkey, following the country's victory at the 2003 contest with the song "Everyway That I Can" by Sertab Erener. Organised by the European Broadcasting Union (EBU) and host broadcaster Turkish Radio and Television Corporation (TRT), the contest was held at the Abdi İpekçi Arena, and, for the first time, consisted of a semi-final on 12 May, and a final on 15 May 2004. The two live shows were presented by Turkish actors Korhan Abay and Meltem Cumbul. It was the first time that Turkey had hosted the contest, 29 years after the country made its debut, and was also the first time since the 1998 contest in Birmingham that it was not hosted in the host country's capital city. This was the only edition of the contest that was hosted in a city other than the host nation's capital in the 21st century, until Germany picked Düsseldorf as the host city for the 2011 edition. Thirty-six countries participated in the contest, beating the record of twenty-six in the previous edition. Albania, Andorra, Belarus and Serbia and Montenegro took part for the first time this year. The old relegation system was replaced with a semi-final format. This was done in order to accommodate the increasing number of countries who wished to participate. The new format allowed all countries to participate every year, rather than being forced to sit out per the relegation rules, which had been the standard since 1994. Because of this, Denmark, Finland, Lithuania, Macedonia, Monaco and Switzerland all returned to the contest, Monaco not having competed since 1979. The winner was Ukraine with the song "Wild Dances", performed by Ruslana who wrote it with her husband Oleksandr Ksenofontov. This was Ukraine's first victory in the contest, only one year after the country made its debut in 2003. Serbia and Montenegro, Greece, Turkey and Cyprus rounded out the top five. Due the expansion of the contest, this year was the first time in which a non-winning entry scored over 200 points. Prior to this contest, only the winning entries in 1994 and 1997 had passed this mark. In this contest, the top 3 songs all got over 200 points. An official CD was released and, for the first time, the entire contest was released on DVD which included the semi-final and the grand final.

The siege of Constantinople in 626 by the Sassanid Persians and Avars, aided by large numbers of allied Slavs, ended in a strategic victory for the Byzantines. The failure of the siege saved the empire from collapse, and, combined with other victories achieved by Emperor Heraclius (r. 610–641) the previous year and in 627, enabled Byzantium to regain its territories and end the destructive Roman–Persian Wars by enforcing a treaty with borders status quo c. 590.

The siege of Constantinople of 1411 occurred during the Ottoman Interregnum, or Ottoman Civil War, (20 July 1402 – 5 July 1413), when chaos reigned in the Ottoman Empire following the defeat of Sultan Bayezid I by the Central Asian warlord Timur. Although Mehmed Çelebi was confirmed as sultan by Timur after the Battle of Ankara, his brothers İsa Çelebi, Musa Çelebi, Süleyman Çelebi, and later, Mustafa Çelebi, refused to recognize his authority, each claiming the throne for himself. A civil war was the result. The Interregnum lasted until the Battle of Camurlu on 5 July 1413, when Mehmed Çelebi emerged as victor in the strife, crowned himself sultan Mehmed I, and restored peace to the empire.

The siege of Constantinople in 1394–1402 was a long blockade of the capital of the Byzantine Empire by the Ottoman Sultan Bayezid I. Already in 1391, the rapid Ottoman conquests in the Balkans had cut off the city from its hinterland. After constructing the fortress of Anadoluhisarı to control the Bosporus strait, from 1394 on, Bayezid tried to starve the city into submission by blockading it both by land and, less effectively, by sea. The Crusade of Nicopolis was launched to relieve the city, but it was decisively defeated by the Ottomans. In 1399, a French expeditionary force under Marshal de Boucicaut arrived, but was unable to achieve much. The situation became so dire that in December 1399 the Byzantine emperor, Manuel II Palaiologos, left the city to tour the courts of Western Europe in a desperate attempt to secure military aid. The emperor was welcomed with honours, but secured no definite pledges of support. Constantinople was saved when Bayezid had to confront the invasion of Timur in 1402. Bayezid's defeat in the Battle of Ankara in 1402, and the Ottoman civil war that followed, even allowed the Byzantines to regain some lost territories, in the Treaty of Gallipoli.
