On what day did the country where Rigatta is from become part of the Soviet Union?
5 August 1940
Title: Germans
Passage: After World War II, eastern European countries such as the Soviet Union, Poland, Czechoslovakia, Hungary, Romania and Yugoslavia expelled the Germans from their territories. Many of those had inhabited these lands for centuries, developing a unique culture. Germans were also forced to leave the former eastern territories of Germany, which were annexed by Poland (Silesia, Pomerania, parts of Brandenburg and southern part of East Prussia) and the Soviet Union (northern part of East Prussia). Between 12 and 16,5 million ethnic Germans and German citizens were expelled westwards to allied-occupied Germany.
Title: Rodoljub Čolaković
Passage: After his release, Rodoljub Čolaković emigrated to the Soviet Union and later took part in the Spanish Civil War on the Republican side.
Title: Rigatta
Passage: Rigatta SIA is a licensed Latvian telecommunications company that provides telephony and network support services in the Baltic states and Frankfurt. Rigatta provides call-by-call, prepaid/postpaid, IP telephony, VoIP telephony, network and also the automatic dialer and network services.
Title: Armenia
Passage: Armenia was annexed by Bolshevist Russia and along with Georgia and Azerbaijan, it was incorporated into the Soviet Union as part of the Transcaucasian SFSR (TSFSR) on 4 March 1922. With this annexation, the Treaty of Alexandropol was superseded by the Turkish-Soviet Treaty of Kars. In the agreement, Turkey allowed the Soviet Union to assume control over Adjara with the port city of Batumi in return for sovereignty over the cities of Kars, Ardahan, and Iğdır, all of which were part of Russian Armenia.
Title: Sweden
Passage: On 27 October 1981, a Whiskey-class submarine (U 137) from the Soviet Union ran aground close to the naval base at Karlskrona in the southern part of the country. Research has never clearly established whether the submarine ended up on the shoals through a navigational mistake or if an enemy committed espionage against Swedish military potential. The incident triggered a diplomatic crisis between Sweden and the Soviet Union. Following the 1986 assassination of Olof Palme and with the end of the Cold War, Sweden has adopted a more traditional foreign policy approach. Nevertheless, the country remains active in peace keeping missions and maintains a considerable foreign aid budget.
Title: Latvian Soviet Socialist Republic
Passage: Following the Welles Declaration of July 23, 1940, the annexation of Latvia into the Soviet Union (USSR) on 5 August 1940 was not recognized as legitimate by the United States, the European Community, and recognition of it as the nominal fifteenth constituent republic of the USSR was withheld for five decades. Its territory was subsequently conquered by Nazi Germany in June -- July 1941, before being retaken by the Soviets in 1944 -- 1945. Nevertheless, Latvia continued to exist as a de jure independent country with a number of countries continued to recognize Latvian diplomats and consuls who still functioned in the name of their former governments.
Title: Kazakhstan
Passage: With an area of 2,700,000 square kilometres (1,000,000 sq mi) – equivalent in size to Western Europe – Kazakhstan is the ninth-largest country and largest landlocked country in the world. While it was part of the Soviet Union, Kazakhstan lost some of its territory to China's Xinjiang autonomous region and some to Uzbekistan's Karakalpakstan autonomous republic.
Title: Space Race
Passage: For its part, the Soviet Union harbored fears of invasion. Having suffered at least 27 million casualties during World War II after being invaded by Nazi Germany in 1941, the Soviet Union was wary of its former ally, the United States, which until late 1949 was the sole possessor of atomic weapons. The United States had used these weapons operationally during World War II, and it could use them again against the Soviet Union, laying waste its cities and military centers. Since the Americans had a much larger air force than the Soviet Union, and the United States maintained advance air bases near Soviet territory, in 1947 Stalin ordered the development of intercontinental ballistic missiles (ICBMs) in order to counter the perceived American threat.
Title: Partial Nuclear Test Ban Treaty
Passage: The PTBT was signed by the governments of the Soviet Union, United Kingdom, and United States in Moscow on 5 August 1963 before being opened for signature by other countries. The treaty formally went into effect on 10 October 1963. Since then, 123 other states have become party to the treaty. Ten states have signed but not ratified the treaty.
