Some 90,000 took to the streets of Warsaw on Saturday to protest the anti-democratic measures of Poland’s ruling, far-right Law and Justice Party. The opposition party, Civic Platform, organized the protest to push back against the ruling party’s attempts to undermine independent Polish institutions.

On May 3, on the anniversary of the signing of Poland’s first constitution, President Andrzej Duda announced his intent to hold a new constitutional referendum, sparking concerns about creeping authoritarianism. The European Union will decide whether it should address these concerns later this month.
