(CNN)When the Czech Republic's 200 newly-elected deputies gathered for the inaugural session of its new parliament on Monday, there wasn't a single Communist party member there -- for the first time in 76 years.
Communists have now left the Czech parliament, more than three decades after the Velvet Revolution
The Communist Party of Bohemia and Moravia (KSCM), the direct successor of the totalitarian Communist Party of Czechoslovakia, has dropped out of the lower house of the Czech parliament after failing to gain any seats in last month's election. The party lost its last seat in the upper house, the Senate, in 2018.
The final departure of the Communists from the top levels of Czech politics marks a hugely symbolic moment for many survivors of the totalitarian regime, especially after the outgoing government of Prime Minister Andrej Babis breached a long-standing taboo and relied on the votes of the Communists in the parliament to secure a majority in 2018, giving them indirect access to power.
While the party has attempted to re-brand itself as a modern and democratic leftist group in recent years, it never fully removed its association with the acts of its totalitarian predecessor.
Marek Benda -- of the Civic Democratic Party and the country's longest serving Member of Parliament -- said he never expected the Communists to stay in parliament for so long after the revolution.
"We thought that they would still have some voters, but that these would gradually disappear ... but they were doing quite well for much longer," Benda said.
Jan Rovny, an associate professor at Sciences Po in Paris, said the decline of the party is down mostly to the "demographic replacement of its elder voters, nostalgic for communist regime certainties."
But, writing in a policy blog, Rovny said the rise of populist parties like Babis' ANO and the far-right SPD have also contributed to the Communists' downfall.
"From its heyday at the helm of the authoritarian regime, the KSCM has been reduced to a radical left protest party in the post-1989 democracy," he wrote. "The recent rise of cultural themes, centering on fears of migration advanced by the SPD and increasingly by ANO, has changed the substance of protest politics. The party's core districts in the post-industrial northern regions have shifted allegiance."
KSCM's leadership resigned following the party's election defeat. Jiri Dolejs, a member of the KSCM board, told CNN that the party's demise reflects a wider downfall of the left in Europe, pointing to other groups that have suffered losses, such as Germany's Die Linke.
"The left has been competing with populists, migration and health crises have pushed away the traditional competition between the left and the right," he said.
Vojtech Filip, the outgoing former KSCM leader, told Halo Noviny, a Czech leftist newspaper closely tied to the party: "It is a great disappointment. The [election] debacle of the KSCM means that for the first time in modern history, the Communist Party will not be part of parliamentary democracy in the Czech Republic. The communists now face the task of doing everything in their power to regain prominence,"
The group's newly-installed leader, Katerina Konecna, said her priority would be working to gain more support among younger people. According to the party's official newspaper, the average age of KSCM members is now 75.
Benda was one of the student leaders of the 1989 revolution and entered parliament shortly after the fall of the communist regime.
