Passage: The first archaeological investigation of the site was carried out in 1964. In that year, the site was noted during an archaeological survey of the region directed by Maurits N. van Loon of the Oriental Institute of the University of Chicago, and a small sounding was made. In 1965, a more extensive excavation was carried out, again under the direction of Van Loon. Between 1971 and 1974, work on the site was resumed by a team of the French Centre national de la recherche scientifique (CNRS) directed by Jacques Cauvin. All excavations were part of the larger international – and eventually UNESCO-coordinated – effort to investigate as many archaeological sites as possible in the area that would be flooded by Lake Assad, the reservoir of the Tabqa Dam, which was being built at that time. The filling of Lake Assad eventually led to the flooding of Mureybet in 1976. Although the site is now submerged and no longer accessible, the material that has been retrieved during the excavations continues to generate new research. This material is currently stored at the National Museum of Aleppo and the Institute de Préhistoire Orientale in Jalès-Berrias in France.

Passage: Mieszko I, Duke of Cieszyn, the first ruler of the duchy, died in 1315 and afterwards his sons divided its land into two parts alongside Biała River: diminished Duchy of Teschen to west and Duchy of Oświęcim to east. In the middle of the 15th century Duchy of Oświęcim was bought into the Crown of the Kingdom of Poland and so the river constituted henceforth the border between Polish and the Bohemian Crown (since 1526 part of the Habsburg Monarchy). Upon the First Partition of Poland in 1772 the river ceased to be a state border and continued as a regional border between Austrian Silesia to the west and Galicia to the east. After World War I and the 1919 Polish–Czechoslovak War it separated the Polish part of Cieszyn Silesia in the Autonomous Silesian Voivodeship from Lesser Polish Kraków Voivodeship.
