The 21 demands of MKS (Polish: 21 postulatów MKS) was a list of demands issued on 17 August 1980 by the Interfactory Strike Committee (Międzyzakładowy Komitet Strajkowy, MKS) in Poland. The first demand was the right to create independent trade unions. Other demands called the government to respect the constitutional rights and freedoms, dismantling the privileges for Polish United Workers' Party members, and taking actions to improve the economic conditions of Polish citizens. The demands eventually led to the Gdańsk Agreement and creation of Solidarity.
