November 3, 1918 — After World War I, the Second Polish Republic was established as an independent state. Among other historically Polish lands, the republic incorporated Russia’s former Grodno District. As a result, Berezna and the surrounding region came under Polish administration once again as part of the new Polesie District in the Kresy (Borderlands) region of Poland. Berezna’s neighboring town, Antopol, appears nearly at the center of this 1920 map showing Poland’s eastern borders (wschodnie granice).
