Poland country profile

Poland can trace its roots back over 1,000 years. Positioned at the centre of Europe, there have been periods of independence as well as periods of domination by other countries.

Several million people, half of them Jews, died in World War Two.

A new era began when Poland became an EU member in May 2004, five years after joining Nato and 15 years after the end of communist rule.

It was the birthplace of the former Soviet bloc's first officially recognised independent mass political movement when strikes at the Gdansk shipyard in August 1980 led to agreement with the authorities on the establishment of the Solidarity trade union.

President: Andrzej Duda

Andrzej Duda of the conservative, Eurosceptic Law and Justice Party, scored a surprise win in the 2015 election, beating the incumbent Bronislaw Komorowski of the centrist Civic Platform in the closest presidential contest in Poland's history.

Born in 1972 and a law lecturer by profession, Mr Duda has been active in conservative politics since the early 2000s, rising to work in the Presidential Chancellery under Lech Kaczynski in 2008-2010.

Prime Minister: Mateusz Morawiecki

Finance Minister Morawiecki took over as head of the Law and Justice party government in December 2017, replacing Beata Szydlo, who moved to the post of deputy prime minister.

In the 2019 general election, the Law and Justice party retained its majority in the Sejm, the lower house, but lost its majority in the Senate, the upper house.

The Western-educated economist Mr Morawiecki has a more polished manner than his predecessor, but also supports a conservative Catholic social agenda, and opposes European Union demands over accepting Muslim refugees.

Poland's broadcasting market is the largest in Eastern and Central Europe. TV is the leading medium.

Many non-state media are owned by foreign companies.

Critics cried foul when the newly-elected conservative Law and Justice government introduced a bill in 2015 to allow ministers to appoint the heads of the public broadcasters TVP and Polish Radio.

Facebook is the leading social network.
