Ozyorsk (Ozërsk)
Ozyorsk (Озёрск, until 1938 Darkehmen; Darkiejmy; Darkiemis; from 1938 to 1946 Angerapp) is a town and the administrative center of Ozyorsky District in Kaliningrad Oblast, Russia, located on the Angrapa River near the border with the Polish Warmian-Masurian Voivodeship, 120 km southeast of Kaliningrad, the administrative center of the oblast. Population:

Before the arrival of the Teutonic Order, the river valley was here settled by the Nadruvians, as evidenced by traces of settlements and fortifications found in the area. Teutonic overlordship was established around 1388, but the town is mentioned for the first time in written sources in 1539 as Darkyem. In 1454, the region was incorporated by King Casimir IV Jagiellon to the Kingdom of Poland upon the request of the anti-Teutonic Prussian Confederation. After the subsequent Thirteen Years' War, since 1466, it formed part of Poland as a fief held by the Teutonic Order, and after 1525 it was located in Ducal Prussia, a vassal duchy of Poland. It was settled by Lithuanian, Polish and German colonists. A first church was built in 1615. From 1701, it formed part of the Kingdom of Prussia. The settlement remained a village until 1724, when it received city rights by Frederick William I of Prussia. Soon afterwards, the town plan was revised with a market square and a new grid plan. An influx of immigrants followed (in 1725, 103 of the 742 registered inhabitants came from Salzburg) and craft production of leather and cloth established in the town. In the 19th century the industry had to close due to competition from more efficient industries in western Germany.

Nine annual fairs were organized in the town in the late 19th century. Due to its location on the Angrapa River, a power station established in the watermill was already in 1880 able to produce electrical light for the town. The town was heavily damaged during fighting in World War I but rebuilt after garden city ideals following the war, with financial support from the city of Dresden.

From 1871 to 1945 the town was part of Germany, within which it was administratively located in the province of East Prussia. Two labour camps of the Reich Labour Service were operated in the town under Nazi Germany. It was captured by the 3rd Belorussian Front of the Red Army on 23 January 1945 in the course of the East Prussian offensive. After Germany's defeat in World War II, the town initially passed to Poland under its historic Polish name Darkiejmy, however, it was soon annexed by the Soviet Union. Its German populace was expelled in accordance to the Potsdam Agreement. It was renamed as Ozyorsk on 7 September 1946.

In 1970, the Department of Printed Circuits was established as a branch of the Radiotechnical Measuring Instruments Factory in Vilnius.

Flag of Russia
Russia (Россия,, ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering 17098246 km2, and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan.

The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE. The first East Slavic state, Kievan Rus', arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire. Rus' ultimately disintegrated, with the Grand Duchy of Moscow growing to become the Tsardom of Russia. By the early 18th century, Russia had vastly expanded through conquest, annexation, and the efforts of Russian explorers, developing into the Russian Empire, which remains the third-largest empire in history. However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and replaced by the Russian SFSR—the world's first constitutionally socialist state. Following the Russian Civil War, the Russian SFSR established the Soviet Union (with three other Soviet republics), within which it was the largest and principal constituent. At the expense of millions of lives, the Soviet Union underwent rapid industrialization in the 1930s, and later played a decisive role for the Allies of World War II by leading large-scale efforts on the Eastern Front. With the onset of the Cold War, it competed with the United States for global ideological influence; the Soviet era of the 20th century saw some of the most significant Russian technological achievements, including the first human-made satellite and the first human expedition into outer space.
