Poland country profile
A nation with a proud cultural heritage, Poland can trace its roots back over 1,000 years. Positioned at the centre of Europe, it has known turbulent and violent times.
There have been periods of independence as well as periods of domination by other countries. Several million people, half of them Jews, died in the Second World War.
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 conservative Law and Justice party government in December 2017, replacing Beata Szydlo, who moved to the post of deputy prime minister.
Law and Justice leader Jaroslaw Kaczynski dropped Mrs Szydlo in what Polish political analysts see as a move to repair the country's poor relations with the European Union, and prepare the party for a series of elections.
The Western-educated economist Mr Morawiecki has a more polished manner than his predecessor, but shares her strong support for Mr Kaczynski's moves to limit the power of the judiciary, promote a conservative Catholic social agenda, and oppose European Union demands to accept 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.
