Protests begin in Poland against the PiS government.

On June 4, 2023, a series of planned anti-government marches took place in several areas of Poland, with the main one being held in the capital city of Warsaw. The protests were additionally motivated by the passing of the bill commonly referred to as "Lex Tusk", which critics argued would disrupt the constitutional separation of powers by giving the ruling party of PiS excessive judicial oversight. The Polish opposition in the national Parliament, as well as numerous foreign commentators, considered the law's approval an extension of the perceived constitutional crisis under the presidency of Andrzej Duda and the government headed by Prime Minister Mateusz Morawiecki.
