The Polish–Soviet War (late autumn 1918 / 14 February 1919 – 18 March 1921) was fought primarily between the Second Polish Republic and the Russian Soviet Federative Socialist Republic in the aftermath of World War I and the Russian Revolution, on territories which were formerly held by the Russian Empire and the Austro-Hungarian Empire.
On 13 November 1918, after the collapse of the Central Powers and the Armistice of 11 November 1918, Vladimir Lenin's Russia annulled the Treaty of Brest-Litovsk (which it had signed with the Central Powers in March 1918) and started moving forces in the western direction to recover and secure the Ober Ost regions vacated by the German forces that the Russian state had lost under the treaty. Lenin saw the newly independent Poland (formed in October–November 1918) as the bridge which his Red Army would have to cross to assist other communist movements and to bring about more European revolutions.
At the same time, leading Polish politicians of different orientations pursued the general expectation of restoring the country's pre-1772 borders. Motivated by this idea, Polish Chief of State Józef Piłsudski (in office from 14 November 1918) began moving troops east.
In 1919, while the Soviet Red Army was still preoccupied with the Russian Civil War of 1917–1922, the Polish Army moved into territories regarded by many Poles as Polish "Kresy". That year, they took most of present-day Lithuania and Belarus. By July 1919, Polish forces had taken control of much of Eastern Galicia and had emerged victorious from the Polish–Ukrainian War of November 1918 to July 1919. In the eastern part of Ukraine bordering on Russia, Symon Petliura tried to defend the Ukrainian People's Republic, but as the Bolsheviks gained the upper hand in the Russian Civil War, they advanced westward towards the disputed Ukrainian lands and made Petliura's forces retreat. Reduced to a small amount of territory in the west, Petliura was compelled to seek an alliance with Piłsudski, officially concluded in April 1920.

The Soviet westward offensive of 1918–1919 was part of the campaign by Soviet Russia into areas abandoned by the Ober Ost garrisons that were being withdrawn to Germany following that country's defeat in World War I. The initially successful offensive against the Republic of Estonia ignited the Estonian War of Independence which ended with the Soviet recognition of Estonia. Similarly, the campaigns against the Republic of Latvia and Republic of Lithuania ultimately failed, resulting in the Latvian–Soviet Peace Treaty and Soviet–Lithuanian Peace Treaty respectively.
Brest, formerly Brest-Litovsk and Brest-on-the-Bug, is a city in Belarus at the border with Poland opposite the Polish city of Terespol, where the Bug and Mukhavets rivers meet, making it a border town. It serves as the administrative center of Brest Region and Brest District, though it is administratively separated from the district. As of 2023, it has a population of 342,461. Brest is a historical site for many cultures, as it hosted important historical events, such as the Union of Brest and Treaty of Brest-Litovsk.
The Ukrainian War of Independence was a military conflict involving many parties from 1917 to 1921 which saw the establishment and development of an independent Ukrainian republic, most of which was later absorbed into the Soviet Union as the Ukrainian Soviet Socialist Republic of 1922–1991. The war consisted of military conflicts between different governmental, political and military forces. Belligerents included Ukrainian nationalists, Ukrainian anarchists, the forces of Germany and Austria-Hungary, the White Russian Volunteer Army, and Second Polish Republic forces.
