The Workers' and Peasants' Red Army, often shortened to the Red Army, was the army and air force of the Russian Soviet Federative Socialist Republic and, after 1922, the Union of Soviet Socialist Republics. The army was established in January 1918. The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Starting in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in 1991.

The Red Army provided the largest land force in the Allied victory in the European theatre of World War II, and its invasion of Manchuria assisted the unconditional surrender of Imperial Japan. During operations on the Eastern Front, it accounted for 7580% of casualties the Wehrmacht and Waffen-SS suffered during the war and ultimately captured the Nazi German capital, Berlin.

Kraków (Polish: [ˈkrakuf] (listen)), also known in English as Cracow, is the second-largest and one of the oldest cities in Poland. Situated on the Vistula River in Lesser Poland Voivodeship, the city dates back to the seventh century. Kraków was the official capital of Poland until 1596 and has traditionally been one of the leading centres of Polish academic, economic, cultural and artistic life. Cited as one of Europe's most beautiful cities, its Old Town with Wawel Royal Castle was declared the first UNESCO World Heritage Site in the world.

The city has grown from a Stone Age settlement to Poland's second-most-important city. It began as a hamlet on Wawel Hill and was reported as a busy trading centre of Central Europe in 965. With the establishment of new universities and cultural venues at the emergence of the Second Polish Republic in 1918 and throughout the 20th century, Kraków reaffirmed its role as a major national academic and artistic centre. The city has a population of about 780,000, with approximately 8 million additional people living within a 100 km (62 mi) radius of its main square.After the invasion of Poland by Nazi Germany at the start of World War II, the newly defined Distrikt Krakau (Kraków District) became the capital of Germany's General Government. The Jewish population of the city was forced into a walled zone known as the Kraków Ghetto, from where they were sent to Nazi extermination camps such as the nearby Auschwitz, and Nazi concentration camps like Płaszów. However, the city was spared from destruction and major bombing.

In 1978, Karol Wojtyła, archbishop of Kraków, was elevated to the papacy as Pope John Paul II—the first non-Italian pope in 455 years. Also that year, UNESCO approved Kraków's entire Old Town and historic centre as its first World Heritage Site alongside Quito. Kraków is classified as a global city with the ranking of "high sufficiency" by the Globalization and World Cities Research Network. Its extensive cultural heritage across the epochs of Gothic, Renaissance and Baroque architecture includes Wawel Cathedral and Wawel Royal Castle on the banks of the Vistula, St. Mary's Basilica, Saints Peter and Paul Church and the largest medieval market square in Europe, Rynek Główny. Kraków is home to Jagiellonian University, one of the oldest universities in the world and traditionally Poland's most reputable institution of higher learning.

In 2000, Kraków was named European Capital of Culture. In 2013, Kraków was officially approved as a UNESCO City of Literature. The city hosted World Youth Day in July 2016.
