Mendeleyevo, Kaliningrad Oblast

Mendeleyevo (Russian: Менделе́ево, German: Poggenpfuhl,[1] Lithuanian: Pogenfulis) is a rural locality (a settlement) in the Guryevsky District, Kaliningrad Oblast, Russia.

In 1454, King Casimir IV Jagiellon incorporated the region to the Kingdom of Poland upon the request of the anti-Teutonic Prussian Confederation.

[2] After the subsequent Thirteen Years' War (1454–1466), it became a part of Poland as a fief held by the Teutonic Knights.

On 30 April 1874 it became the seat of Amtsbezirk Poggenpfuhl within East Prussia.

[6] Poggenpfuhl was transferred to the Soviet Union in 1945 after World War II and subsequently renamed Mendeleyevo in 1946.
