The so-called Nooshi Dadgostar effect was also felt for the Young Left.
In a typical week, the union gets about 20 new members.
The week before and after the no-confidence vote, the number doubled, according to their figures.
- I think it is super good and positive that so many young people get involved in politics and know that it also shapes their lives.
It is not an adult issue with politics.
It affects everyone, says Ava Rudberg, union chairman of the Young Left.
Membership losses have stopped
Historically, the number of members in the political youth unions is small, even though the figures back in time are somewhat uncertain.
For decades, the number of members has plummeted from around 220,000 members in the mid-1970s to today's just over 30,000 members.
But now a trend break can be seen.
This is the opinion of political scientist Niklas Bolin, who runs a research project on the Swedish Political Youth Association at Mid Sweden University in Sundsvall.
- If you look back about 15 years, we see a small increase in the number of members.
It is a positive signal given that the youth unions lost very many members until the 80s, 90s and 2000s.
A turn that is at least a positive sign, says Niklas Bolin.
"Had many friends in Muf"
The moderate youth union MUF is the largest among the political unions in Sweden with just over 10,000 members.
Elin Landys Herre is 17 years old and grew up in Stockholm.
She joined just before the pandemic began.
- I have always been interested in politics since we talked about it in school and so on.
Then I had many friends and my big sister who were involved in the Moderate Youth Association, she says.
Adults remain
Niklas Bolin's research also shows that many members want to continue to get involved in the political parties after their youth.
Amanda Jemander joined the Young Left two and a half years ago.
- You do not join the Young Left to get a career or become a politician.
But I hope that I will always be involved in politics and be involved in a good way, she says.
