After the 2015 parliamentary elections in Poland, the parties that moved to the opposition declared themselves the “total opposition” and adopted the “Street and Abroad” strategy, the aim of which was to organise anti-government protests in the country and to use foreign fora, including above all EU mechanisms, to fight the new right-wing government, criticise its actions and eventually remove it from power. The aim of this presentation is to assess the effectiveness of the strategy adopted by the Polish opposition after 7 years of right-wing rule. The subject of particular interest is, on the one hand, the evaluation of the effectiveness of the “Street” strategy on the example of mass protests concerning courts, abortion and the media. On the other hand, the “Foreign”strategy was analysed through the impact of the European Parliament's resolution on social mobilisation, electoral preferences and the level of support for the ruling party.
