Solotvyno was first mentioned . The former town was burned down by the
Tatars in 1241. In 1910, the town had a population of 2,330, the majority of whom were Hungarian. In 1920, with the collapse of the
Austro-Hungarian empire, the town was divided in two, with the northern part of the right bank of the Tisza river becoming a part of the newly formed Czechoslovakia. The southern part became
Sighet in
Romania. In March 1939 the area was
invaded and annexed by
Hungary. Almost the entire Jewish population was murdered in
the Holocaust. In April 1944, Hungarian authorities established a ghetto in the Solotvino as part of the wider
ghettoization of the region, confining Jews in overcrowded, unsanitary conditions that led to rampant starvation and disease. On 25 May 1944, the remaining Jews of Solotvino were deported on a single train carrying 3,317 people to Auschwitz, where the majority were murdered in gas chambers on arrival. After
World War II, Solotvino with the rest of
Carpathian Ukraine became part of Ukraine in the
Soviet Union. Under Soviet rule, Solotvyno's salt works were nationalized and integrated into the state-run Ukrsolprom, with extraction peaking at 451,000 tonnes per year in the 1970s, representing around 10% of Ukraine's total salt production.
Speleotherapy, pioneered in Solotvyno during Soviet times, saw the 1968 founding of an experimental allergological hospital in Mine No. 8, with Mine No. 9’s underground chambers officially opened in 1976 to treat asthma and other respiratory diseases as a sanctioned USSR medical therapy. According to the 2001 Ukrainian Census, the majority of the population in the city is Romanian. In 2001, 56.97% of the 8,956 inhabitants spoke
Romanian as their native language, while 14.54% spoke Ukrainian, 24.3%
Hungarian, and 3.18% Russian. Until 26 January 2024, Solotvyno was designated
urban-type settlement. On this day, a new law entered into force which abolished this status, and Solotvyno became a rural settlement. == Geography ==
