Těrlicko consists of three municipal parts (in brackets population according to the 2021 census):[2] The name could be derived from the so-called cierlice, which was a tool used to comb flax.

It lies in the historical region of Cieszyn Silesia, in the western part of the Moravian-Silesian Foothills.

[3] Těrlicko was first mentioned in the document of Pope Gregory IX issued for Benedictine abbey in Tyniec in 1229 as Cierlitzko.

The monks brought settlers to the area who were engaged in agriculture, especially flax growing and sheep farming.

[3] The village probably became a seat of a Catholic parish prior to the 16th century, and also a church in the hamlet of Kostelec was built.

They were taken from them (as two from around fifty buildings) in the region by a special commission and given back to the Roman Catholic Church on 24 March 1654.

According to the censuses conducted in 1880–1910 the population of Dolní Těrlicko grew from 454 in 1880 to 617 in 1910 with a majority being native Polish-speakers (between 97.2% and 99.1%) accompanied by a few German-speaking persons (at most or 2.5% in 1890).

In Horní Těrlicko the population dropped from 1452 in 1880 to 1390 in 1910 with a majority being native Polish-speakers (between 98.6% and 99.7%) accompanied by a few German-speakers (at most 10 or 0.7% in 1910) and Czech-speakers (at most 9 or 0.7% in 1910).

Following the Munich Agreement, in October 1938 together with the Trans-Olza region they were annexed by Poland, administratively adjoined to Cieszyn County of Silesian Voivodeship.

[16] Larisch's manor is a former aristocratic residence from the early 19th century, built in the Empire style.

Later it was fortified and equipped with a permanent guard, which took care of the safety of passengers on the road and collected tolls.

The monument is in the form of a life-size pilot, who holds a twig of victory and leans on the propeller of a plane.
