Border Agreement Between Poland and The USSR of 16 August 1945 - Aftermath

Aftermath

Although the treaty finalised the 1939 line, with the 1944/45 adjustments, the border would receive a few more alterations. On 15th of May 1948, the raion of Medyka was transferred from the Drohobych Oblast of Ukraine to the Republic of Poland. And finally a 1951 Polish–Soviet territorial exchange, saw Poland return its pre-1939 territory of Ustrzyki Dolne raion from the Drohobych Oblast, and instead it passed the USSR part of the Lublin Voivodship, with the cities of Belz, Uhniv, Chervonohrad and Varyazh, (all of which after the Nazi & Soviet Axis invasion of Poland in September 1939 became a part of Poland occupied by the USSR and was allocated to Ukraine in 1939 until 1941 when the Nazis invaded the Soviet Union. It was occupied again in 1944-1945 after the Soviet advance to Berlin). The border between Poland and Belarus, and Poland and Ukraine has remained the same since.
