On Nov. 1, German police arrested more than 200 people after violent clashes erupted in several cities following largely peaceful Generation Z demonstrations demanding better education funding and social policies.

The main daytime protests, organised by the Gen Z Regelt initiative in more than 30 cities, drew tens of thousands of young people demanding increased education funding, relief from rising living costs and opposition to plans to revive compulsory military service.
