The first written mention of Třinec is from 1444, but the village was probably founded already in the second half of the 14th century.[5] Politically, the village then belonged to theDuchy of Teschen, afee of theKingdom of Bohemia, which after 1526 became part of theHabsburg monarchy. In 1770, the village had about 200 inhabitants and was completely agricultural.[5]
The area was rich iniron ore deposits and had sufficient water energy and a high supply of wood, which were the main reasons to establish aniron works there. The iron mill began operation in 1839, becoming the largest in the entireCieszyn Silesia, and became a major milestone in the history of the village, which reoriented itself to industry. After the construction of theKošice–Bohumín Railway line in 1871, rapid development of the town took place.[6]
After therevolutions of 1848 in the Austrian Empire, a modernmunicipal division was introduced in the re-establishedAustrian Silesia. The village as a municipality was added to thepolitical andlegal district ofCieszyn. According to censuses conducted in 1880–1910, the population of the municipality grew from 1,792 in 1880 to 3,849 in 1910, with a majority being native Polish speakers (growing from 51.4% in 1880 to 96.6% in 1900 and 96% in 1910), accompanied by a German-speaking minority (at most 32.5% in 1880, then dropping to 12.2% in 1900, and up to 24.3% in 1910) and Czech speakers (peaking in 1890 at 17.4%, then dropping to 6.7% in 1910). In terms of religion, in 1910 the majority wereRoman Catholics (63.2%), followed byProtestants (34.5%), andJews (1.9%).[7] The village was also traditionally inhabited byCieszyn Vlachs, speaking theCieszyn Silesian dialect.
In 1946, the villages ofLyžbice,Dolní Líštná, andKonská were joined to Třinec. In 1956–1977, a large housing estate was built in Lyžbice, and it became the most populated town part of Třinec.[10] Afterwards, Lyžbice became a newdowntown, taking the place ofStaré Město (lit. "old town").
TheTřinec Iron and Steel Works company is one of the largest employers in the Czech Republic. Including smaller production plants outside Třinec, the company employs 7,000 people (as of 2021).[15]
