Szeged in the context of Diocese of Szeged–Csanád

The Treaty of Edirne and the Peace of Szeged were two halves of a peace treaty between Sultan Murad II of the Ottoman Empire and King Vladislaus of the Kingdom of Hungary. Despot Đurađ Branković of the Serbian Despotate was a party to the proceedings. The treaty brought an end to the Christian crusade against the Ottomans with significant gains. Within a month Vladislaus abjured his oath at the urging of the papacy and the crusade continued. On 10 November 1444 it ended in disaster at the Battle of Varna where the crusaders were wiped out and Vladislaus killed.

The treaty was started in Edirne with discussions between Murad and Vladislaus' ambassador. Within a few days, it was sent to Szeged with Murad's ambassador, to be finalized and ratified by Vladislaus. Once it arrived, complications caused the negotiations to continue for several more days, and oaths were eventually given in Várad. The ratification took place on 15 August 1444 in Várad.

The Banat Swabians are an ethnic German population in the former Kingdom of Hungary in Central-Southeast Europe, part of the Danube Swabians and Germans of Romania. They emigrated in the 18th century to what was then the Austrian Empire's Banat of Temeswar province, a province which had been left sparsely populated by the wars with the Ottoman Empire. At the end of World War I in 1918, the Swabian minority worked together with the Hungarians and Jews to establish an independent multi-ethnic Banat Republic; however, the province was divided by the Treaty of Versailles of 1919, and the Treaty of Trianon of 1920. The greater part was annexed by Romania, a smaller part by the Kingdom of Serbs, Croats and Slovenes (since 1929 Yugoslavia) and a small region around Szeged remained part of Hungary.

Following World War II most Banat Swabians were expelled to the West by the Soviet Union and its subsidiaries, and after 1990 and the fall of the Soviet Union and its republics many of those remaining left for economic and emotional reasons.

The Tisza, Tysa or Tisa (see below) is one of the major rivers of Central and Eastern Europe. It was once called "the most Hungarian river" because it flowed entirely within the territory of the Kingdom of Hungary. Today, it crosses several national borders.

The Tisza begins near Rakhiv in Ukraine, at the confluence of the White Tisza and Black Tisza, which is at coordinates 48°4′29″N 24°14′40″E / 48.07472°N 24.24444°E / 48.07472; 24.24444 (the former springs in the Chornohora mountains; the latter in the Gorgany range). From there, the Tisza flows west, roughly following Ukraine's borders with Romania and Hungary, then briefly forming the border between Slovakia and Hungary, before entering into Hungary, and finally into Serbia. The Tisza enters Hungary at Tiszabecs, traversing the country from north to south. A few kilometers south of the Hungarian city of Szeged, it enters Serbia. Finally, it joins the Danube near the village of Stari Slankamen in Vojvodina, Serbia.

The Mureș (Romanian: [ˈmureʃ]) or Maros (Hungarian: [ˈmɒroʃ]; German: Mieresch, Serbian: Мориш / Moriš) is a 789-kilometre-long (490 mi) river in Eastern Europe. Its drainage basin covers an area of 30,332 km (11,711 sq mi). It originates in the Hășmașu Mare Range in the Eastern Carpathian Mountains, Romania, rising close to the headwaters of the river Olt, and joins the Tisza at Szeged in southeastern Hungary. In Romania, its length is 761 km (473 mi) and its basin size is 27,890 km (10,770 sq mi).

The Mureș River flows through the Romanian counties Harghita, Mureș, Alba, Hunedoara, Arad and Timiș, and the Hungarian county Csongrád. The largest cities on the Mureș/Maros are Târgu Mureș, Alba Iulia, Deva and Arad in Romania as well as Makó and Szeged in Hungary.
