History

The town arose through a merger of two villages, Hájniky and Rybáre, in 1959 and was given the name "Sliač". However, both original settlements are much older. The Gothic church in Hájniky was mentioned for the first time in 1263 (when the territory belonged to the Kingdom of Hungary) and there is archaeological evidence of Slavic settlers living in the area since the 6th century. Some evidence also indicates that the history of the settlement stretches to 2000 B.C. Before the establishment of independent Czechoslovakia in 1918, Sliač was part of Zólyom County within the Kingdom of Hungary. From 1939 to 1945, it was part of the Slovak Republic. Sliač Airport, formerly known as Letisko Tri Duby ("Three-Oaks Airport") due to the name of the area it was located in, played a key strategic role during the Slovak National Uprising.

Note on population

The difference between the population numbers above and in the census (here and below) is that the population numbers above are mostly made up of permanent residents, etc.; and the census should indicate the place where people actually mainly live. For example, a student is a citizen of a village because he has permanent residence there (he lived there as a child and has parents), but most of the time he studies at a university in the city.
