History of Poland

Poland's written history begins with the reign of Mieszko I, who accepted Christianity for himself and his kingdom in AD 966. The Polish state reached its zenith under the Jagiellonian dynasty in the years following the union with Lithuania in 1386 and the subsequent defeat of the Teutonic Knights at Grunwald in 1410. The monarchy survived many upheavals but eventually went into decline, which ended with the third and final partition of Poland by Prussia, Russia, and Austria in 1795.

Independence for Poland was one of the 14 points enunciated by President Woodrow Wilson during World War I. Many Polish Americans enlisted in the military services to further this aim, and the United States worked at the postwar conference to ensure its implementation.

However, the Poles were largely responsible for achieving their own independence in 1918. Authoritarian rule predominated for most of the period before World War II. On August 23, 1939, Germany and the Soviet Union signed the Ribbentrop-Molotov nonaggression pact, which secretly provided for the dismemberment of Poland into Nazi and Soviet-controlled zones. On September 1, 1939, Hitler ordered his troops into Poland. On September 17, Soviet troops invaded and then occupied eastern Poland under the terms of this agreement. After Germany invaded the Soviet Union in June 1941, Poland was completely occupied by German troops.

The Poles formed an underground resistance movement and a government in exile, first in Paris and later in London, which was recognized by the Soviet Union. During World War II, 400,000 Poles fought under Soviet command, and 200,000 went into combat on Western fronts in units loyal to the Polish government in exile.

In April 1943, the Soviet Union broke relations with the Polish government in exile after the German military announced that they had discovered mass graves of murdered Polish army officers at Katyn, in the U.S.S.R. (The Soviets claimed that the Poles had insulted them by requesting that the Red Cross investigate these reports.) In July 1944, the Soviet Red Army entered Poland and established a communist-controlled "Polish Committee of National Liberation" at Lublin.

Resistance against the Nazis in Warsaw, including uprisings by Jews in the Warsaw ghetto and by the Polish underground, was brutally suppressed. As the Germans retreated in January 1945, they leveled the city.

During the war, about 6 million Poles were killed, and 2.5 million were deported to Germany for forced labor. More than 3 million Jews (all but about 100,000 of the Jewish population) were killed in Nazi death camps like those at Auschwitz, Treblinka, and Sobibor.

Following the Yalta Conference in February 1945, a Polish Provisional Government of National Unity was formed in June 1945; the U.S. recognized it the next month. Although the Yalta agreement called for free elections, those held in January 1947 were controlled by the Communist Party. The communists then established a regime entirely under their domination.
