After the Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. The village as a municipality was subscribed to the political district of Cieszyn and the legal district of Jablunkov (at least from 1880). According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the municipality grew from 1,013 in 1880 to 1,251 in 1910 with a majority being native Polish-speakers (between 96.7% and 99.7%) accompanied by Czech-speaking (at most 23 or 2.3% in 1880) and German-speaking people (at most 10 or 1% in 1880). In terms of religion in 1910 the majority were Protestants (78.4%), followed by Roman Catholics (21.6%).[5] The village was also traditionally inhabited by Cieszyn Vlachs, speaking Cieszyn Silesian dialect.
Until the rapid expansion of Třinec in the 20th century, it was a larger and more populous village than Třinec.
In 1946 Lyžbice were merged with the town of Třinec and became a place where in the 1950s the ruling Communist Party of Czechoslovakia began a large scale development in the style of socialist realism. Afterwards Lyžbice became a new downtown, overtaking the role from Staré Město (lit. Old Town).
