Western Belarus in the context of "Lithuanian Soviet Socialist Republic"

Belarus, officially the Republic of Belarus, is a landlocked country in Eastern Europe. It is bordered by Russia to the east and northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Belarus spans an area of 207,600 square kilometres (80,200 sq mi) with a population of 9.1 million. The country has a hemiboreal climate and is administratively divided into six regions. Minsk is the capital and largest city; it is administered separately as a city with special status.

For most of the medieval period, the lands of modern-day Belarus was ruled by independent city-states such as the Principality of Polotsk. Around 1300 these lands came fully under the Grand Duchy of Lithuania and subsequently by the Polish–Lithuanian Commonwealth; this period lasted for 500 years until the 1792-1795 partitions of Poland-Lithuania placed Belarus within the Russian Empire for the first time. In the aftermath of the Russian Revolution in 1917, different states arose competing for legitimacy amid the Civil War, ultimately ending in the rise of the Byelorussian SSR, which became a founding constituent republic of the Soviet Union in 1922. After the Polish-Soviet War (1918–1921), Belarus lost almost half of its territory to Poland. Much of the borders of Belarus took their modern shape in 1939, when some lands of the Second Polish Republic were reintegrated into it after the Soviet invasion of Poland, and were finalized after World War II. During World War II, military operations devastated Belarus, which lost about a quarter of its population and half of its economic resources. In 1945, the Byelorussian SSR became a founding member of the United Nations, along with the Soviet Union. The republic was home to a widespread and diverse anti-Nazi insurgent movement which dominated politics until well into the 1970s, overseeing Belarus's transformation from an agrarian to an industrial economy.

Eastern Borderlands (Polish: Kresy Wschodnie), often simply Borderlands (Polish: Kresy, Polish pronunciation: [ˈkrɛsɨ]) was a historical region of the eastern part of the Second Polish Republic. The term was coined during the interwar period (1918–1939). Largely agricultural and extensively multi-ethnic with a Polish minority, it amounted to nearly half of the territory of interwar Poland. Historically situated in the eastern Polish–Lithuanian Commonwealth, following the 18th-century foreign partitions it was divided between the Empires of Russia and Austria-Hungary, and ceded to Poland in 1921 after the Treaty of Riga. As a result of the post-World War II border changes, all of the territory was ceded to the Soviet Union, and today the area of Kresy is divided between Western Ukraine, Western Belarus, and south-eastern Lithuania.

The region gave rise to the Kresy myth, a collection of nostalgic views about the area. After the fall of Communism in Europe and dissolution of the Soviet Union a major economic conflict emerged about the real estate lost by Poland with the loss of Kresy.

The Bielski partisans were a unit of Polish Jewish partisans who rescued Jews from extermination and fought the German occupiers and their collaborators around Novogrudok and Lida in German-occupied Poland (now western Belarus). The partisan unit was named after the Bielskis, a family of Polish Jews who organized and led the community.

The Bielski partisans spent more than two years living in the forest. By the end of the war they numbered as many as 1,236 members, most of whom were non-combatants, including children and the elderly. The Bielski partisans are seen by many Jews as heroes for having led as many refugees as they did away from the perils of war and the Holocaust. However, as their relations with the non-Jewish population were strained and occasionally violent, their wartime record has been the subject of some controversy in Poland.

The Lublin–Brest Offensive (Russian: Люблин‐Брестская наступательная операция, romanized: Lyublin-Brestskaya nastupatel'naya operatsiya, 18 July – 2 August 1944) was a part of the Operation Bagration strategic offensive by the Soviet Red Army to clear the Nazi German forces from the regions of Eastern Poland and Western Belarus. The offensive was executed by the left (southern) wing of the 1st Belorussian Front and took place during July 1944; it was opposed by the German Army Group North Ukraine and Army Group Centre.

The operation was accompanied by several other offensives, particularly the Lvov–Sandomierz Offensive of the 1st Ukrainian Front in the south; both offensives launched weeks after the start of the successful Operation Bagration to the north which cleared German forces from most of Belarus.
