Following the Second World War, most breweries were nationalized by the Communist Government of the Polish People's Republic. After the collapse of communism and return to capitalism, the market economy returned, international beer companies moved in and a period of consolidation followed. Three companies now control 80% of the Polish beer market (according to data at the end of 2014). At the end of 2013, there were 97 breweries in Poland, including microbreweries and contracted breweries. The most popular Polish beers are Żywiec, Okocim, Tyskie, and Zubr.
