Western Belorussia or Western Belarus is a historical region of modern-day Belarus which belonged to the Second Polish Republic during the interwar period. For twenty years before the 1939 invasion of Poland, it was the northern part of the Polish Kresy macroregion. Following the end of World War II in Europe, most of Western Belorussia was ceded to the Soviet Union by the Allies, while some of it, including Białystok, was given to the Polish People's Republic. Until the dissolution of the Soviet Union in 1991, Western Belorussia formed the western part of the Byelorussian Soviet Socialist Republic (BSSR). Today, it constitutes the west of modern Belarus.

When the Second World War in Europe began, the territory which now forms the country of Belarus was divided between the Soviet Union and the Second Polish Republic. The borders of Soviet Belarus were greatly expanded in the Soviet invasion of Poland of 1939. In 1941, the country was occupied by Nazi Germany. Following the German military disasters at Stalingrad and Kursk, the collaborationist Belarusian Central Council (BCC) was formed by the Germans in order to raise local support for their anti-Soviet operations. The BCC in turn formed the twenty-thousand strong Belarusian Home Defence (BKA), active from 23 February 1944 to 28 April 1945. Assistance to collaborators was offered by the local Soviet administrative governments, and prewar public organizations including the former Soviet Belarusian Youth. The country was soon retaken by the Red Army in 1944. Devastated by the war, Belarus lost significant populations and economic resources. Many battles occurred in Belarusian territory. Belarusians also participated in the advance towards Berlin.
The Belarusian minority in Poland is composed of 47,000 people according to the Polish census of 2011. This number decreased in the last decades from over 300,000 due to an active process of assimilation. Most of them live in the Podlaskie Voivodeship.
Bialystok District was an administrative unit of Nazi Germany created during the World War II invasion of the Soviet Union. It was to the south-east of East Prussia, in present-day northeastern Poland as well as in smaller sections of adjacent present-day Belarus and Lithuania. It was sometimes also referred to by the designation South East Prussia along with the Regierungsbezirk Zichenau, although in contrast to the latter, it was not incorporated into, but merely attached to East Prussia.
Białystok Voivodeship was an administrative division and local government in Poland from 1944 to 1975, when its purview was separated into eastern Suwałki Voivodeship, Łomża Voivodeship and Białystok Voivodeship (1975–1998). Its capital city was Białystok. The establishment of Podlaskie Voivodeship in 1999 was essentially a reunion of the areas of Białystok Voivodeship (1945–1975).
The Border Agreement between Poland and the USSR of 16 August 1945 established the borders between the Union of Soviet Socialist Republics (USSR) and the Republic of Poland. It was signed by the Provisional Government of National Unity formed by the Polish communists. According to the treaty, Poland officially accepted the ceding its pre-war Eastern territory to the USSR (Kresy) which was decided earlier in Yalta already. Some of the territory along the Curzon line, established by Stalin during the course of the war, was returned to Poland. The treaty also recognised the division of the former German East Prussia and ultimately approved the finalised delimitation line between the Soviet Union and Poland: from the Baltic Sea, to the border tripoint with Czechoslovakia in the Carpathians. The agreement entered into force on 5 February 1946.
Elections to the People's Assemblies of Western Ukraine and Western Belorussia, which took place on October 22, 1939, were an attempt to legitimize the annexation of the Second Polish Republic's eastern territories by the Soviet Union following the September 17 Soviet invasion of Poland in accordance with the secret protocol of the Molotov–Ribbentrop Pact. Only one month after these lands were occupied by the Red Army, the Soviet secret police and military led by the Party officials staged the local elections in an atmosphere of state terror. The referendum was rigged. The ballot envelopes were numbered and often handed over already sealed. By design, the candidates were unknown to their constituencies which were brought to the voting stations by armed militias. The results were to become the official legitimization of the Soviet takeover of what is known today as the Western Belorussia and the Western Ukraine. Consequently, both Assemblies voted for incorporation of all formerly Polish voivodeships into the Soviet Union.
Throughout its early history, the area comprising the current day Podlaskie Voivodeship was inhabited by various tribes of different ethnic roots. In the 9th and 10th centuries, the area was likely inhabited by Lechitic tribes in the west and south, Baltic (Yotvingian) tribes in the north, and East Slavic tribes in the east. Between the 10th and 13th centuries, the area was mostly divided between Poland, Ruthenian principalities and the Yotvingians, and by the 14th century, it was divided between the Kingdom of Poland and the Grand Duchy of Lithuania. In 1569, after the Union of Lublin, most of the current voivodeship was reintegranted with the Kingdom of Poland.
On the basis of a secret clause of the Molotov–Ribbentrop Pact, the Soviet Union invaded Poland on September 17, 1939, capturing the eastern provinces of the Second Polish Republic. The eastern provinces of interwar Poland were inhabited by an ethnically mixed population, with ethnic Poles as well as Polish Jews dominant in the cities. These lands now form the backbone of modern Western Ukraine and Western Belarus.
The population exchange between Poland and Soviet Belarus at the end of World War II (1944–1947) was based on an agreement signed on 9 September 1944 by the Byelorussian SSR with the newly-formed Polish Committee of National Liberation (PKWN). It stipulated the resettlement of ethnic Belarusians from Poland to Belarus and of ethnic Poles and Jews who had Polish citizenship before September 17, 1939 from Belarus to Poland, in accordance with the resolutions of the Yalta and Tehran conferences and the plans about the new Belarus–Poland border. Similar agreements were signed with the Ukrainian SSR and the Lithuanian SSR ; the three documents are commonly known as the Republican Agreements.
