Katyn massacre in the context of "Lavrentiy Beria"

Lech Aleksander Kaczyński (Polish: [ˈlɛx alɛkˈsandɛr kaˈt͡ʂɨj̃skʲi] ; 18 June 1949 – 10 April 2010) was a Polish politician who served as the city mayor of Warsaw from 2002 until 2005, and as President of Poland from 2005 until his death in 2010 in a plane crash in the vicinity of the Russian city of Smolensk. The aircraft carrying him and senior Polish officials had crashed while they were travelling to attend ceremonies marking the 70th anniversary of the Katyn massacre. Prior to his tenure as president, Kaczyński served as President of the Supreme Audit Office from 1992 to 1995 and later Minister of Justice and Public Prosecutor General in Jerzy Buzek's cabinet from 2000 until his dismissal in July 2001.

Born in Warsaw, he starred in a 1962 Polish film, The Two Who Stole the Moon, with his identical twin brother Jarosław. Kaczyński was a graduate of law and administration of Warsaw University. In 1980, he was awarded his Ph.D. by Gdańsk University. In 1990, he completed his habilitation in labour and employment law. He later assumed professorial positions at Gdańsk University and Cardinal Stefan Wyszyński University in Warsaw.

The Vinnytsia massacre was the mass execution of between 9,000 and 11,000 people in the Ukrainian town of Vinnytsia by the Soviet secret police NKVD during the Great Purge in 1937–1938, which Nazi Germany discovered during its occupation of Ukraine in 1943. The investigation of the site first conducted by the international Katyn Commission coincided with the discovery of a similar mass murder site of Polish prisoners of war in Katyn. Among the 679 dead identified by the Germans in 1943, there were also a certain number of Russians and 28 Poles (according to the latest data, the number of Poles killed by the NKVD in the city could amount to over 3,000). Nazi propaganda invoked mention of the massacre to illustrate communist terror by the Soviet Union.

On 10 April 2010, a Tupolev Tu-154 aircraft operating Polish Air Force Flight PLF 101 crashed near the Russian city of Smolensk, killing all 96 people on board. Among the victims were the president of Poland, Lech Kaczyński, and his wife, Maria; the former president of Poland-in-exile, Ryszard Kaczorowski; the chief of the Polish General Staff and other senior Polish military officers; the president of the National Bank of Poland; Polish government officials; 18 members of the Polish parliament; senior members of the Polish clergy; and relatives of victims of the Katyn massacre. The group was arriving from Warsaw to attend an event commemorating the 70th anniversary of the massacre, which took place not far from Smolensk.

The pilots were attempting to land at Smolensk North Airport — a former military airbase — in fog, with visibility reduced to about 400 metres (about 400 yards). The aircraft descended far below the normal approach path until it struck trees, rolled, inverted and crashed into the ground, coming to rest in a wooded area a short distance from the runway.

Enigma is a 2001 espionage thriller film directed by Michael Apted from a screenplay by Tom Stoppard. The script was adapted from the 1995 novel Enigma by Robert Harris, about the Enigma codebreakers of Bletchley Park in the Second World War.

Although the story is highly fictionalised, the process of encrypting German messages during World War II and decrypting them with the Enigma is discussed in detail, and the historical event of the Katyn massacre is highlighted. It was the last film scored by John Barry.

The Katyn Commission or the International Katyn Commission was a committee formed in April 1943 under request by Germany to investigate the Katyn massacre of some 22,000 Polish nationals during the Soviet occupation of Eastern Poland, mostly prisoners of war from the invasion of Poland including Polish Army officers, intelligentsia, civil servants, priests, police officers and numerous other professionals. Their bodies were discovered in a series of large mass graves in the forest near Smolensk in Russia following Operation Barbarossa.

An international commission of experts in anatomy and forensic pathology were brought in from 11 countries in Europe, predominantly from Nazi Germany's allied or occupied states. The Commission concluded that the Soviet Union had been responsible for the massacre. Consequently, the German government made extensive reference to the massacre in its own propaganda in an attempt to drive a political wedge between the Allies of World War II. The severing of relations between the Polish government-in-exile and the Soviet Union was a direct result of Polish support for the investigation.

The Smolensk air disaster, included Polish Air Force Flight 101 in 2010 killing all 96 people on board. The Polish delegation was heading to Katyn to attend a ceremony marking the 70th anniversary of the Katyn massacre, in which the Soviet NKVD killed about 22,000 Polish military officers.

Among those killed in the crash of Flight 101 were Polish President Lech Kaczyński, his wife Maria Kaczyńska, former President-in-exile Ryszard Kaczorowski, Poland's highest-ranking military officers, lawmakers, heads of the Polish National Bank and other central institutions, presidential aides, bishops and priests of various denominations, relatives of those killed in the Katyn massacre, as well as officers of the presidential security detail and crew members.
