Hong Kong’s biggest pro-democracy party voted Sunday to dissolve after more than 30 years of activism, marking the end of an era of the Chinese semiautonomous city ‘s once-diverse political landscape.

Democratic Party chairperson Lo Kin-hei said the political environment was “one important point” among the factors they considered, and about 97% of members’ ballots were in support of its liquidation. He said it is the best way forward for its members.

Party veterans had earlier told The Associated Press that some members were warned of consequences if the party didn’t shut down.
