88-555: In response to a sizable requirement for a common jet-propelled trainer to be adopted across the diverse nations of the Eastern Bloc , Aero decided to embark upon their own design project with a view to suitably satisfying this demand. On 5 April 1959, an initial prototype, designated as the XL-29 , performed its maiden flight . The L-29 was selected to become the standard trainer for the air forces of Warsaw Pact nations, for which it

176-531: A " sovietization " of Central Europe. In addition to reparations, Stalin pushed for "war booty", which would permit the Soviet Union to directly seize property from conquered nations without quantitative or qualitative limitation. A clause was added permitting this to occur with some limitations. At first, the Soviets concealed their role in other Eastern Bloc politics, with the transformation appearing as

264-688: A "loophole" through which Eastern Bloc citizens could still move west. The 3.5 million East Germans that had left by 1961, called Republikflucht , totaled approximately 20% of the entire East German population. In August 1961, East Germany erected a barbed-wire barrier that would eventually be expanded through construction into the Berlin Wall , effectively closing the loophole. With virtually non-existent conventional emigration, more than 75% of those emigrating from Eastern Bloc countries between 1950 and 1990 did so under bilateral agreements for "ethnic migration". About 10% were refugee migrants under

352-645: A Polish civilian biplane piloted by Dionizy Bielański, who had been attempting to defect to the West . The L-29 was supplanted in the inventory of many of its operators by the Aero L-39 Albatros . The L-29 which was commonly used alongside the newer L-39 for a time. The type was used extensively to conduct ground attack missions in the First Nagorno-Karabakh War by Azeri forces. At least 14 were shot down by Armenian air-defences, out of

440-610: A broader democratic basis in Poland. He stated that the new government's primary task would be to prepare elections. However, the 1946 Polish people's referendum (known as the "Three Times Yes" referendum) and the subsequent 1947 Polish parliamentary election did not meet democratic standards and were largely manipulated. The parties at Yalta further agreed that the countries of liberated Europe and former Axis satellites would be allowed to "create democratic institutions of their own choice", pursuant to "the right of all peoples to choose

528-577: A death sentence and execution. A number of other high ranking Bulgarian officials were also jailed. Stalin and Hungarian leader Mátyás Rákosi met in Moscow to orchestrate a show trial of Rákosi opponent László Rajk , who was thereafter executed. The preservation of the Soviet bloc relied on maintaining a sense of ideological unity that would entrench Moscow's influence in Eastern Europe as well as

616-419: A distance. In addition to emigration restrictions, civil society, defined as a domain of political action outside the party's state control, was not allowed to firmly take root, with the possible exception of Poland in the 1980s . While the institutional design of the communist systems were based on the rejection of rule of law, the legal infrastructure was not immune to change reflecting decaying ideology and

704-482: A large-scale party programs to train personnel who would meet political requirements. Former members of the middle-class were officially discriminated against, though the state's need for their skills and certain opportunities to re-invent themselves as good Communist citizens did allow many to nonetheless achieve success. Communist regimes in the Eastern Bloc viewed marginal groups of opposition intellectuals as

792-710: A late September 1947 meeting of all communist parties in Szklarska Poręba , Eastern Bloc communist parties were blamed for permitting even minor influence by non-communists in their respective countries during the run up to the Marshall Plan. In the former German capital Berlin, surrounded by Soviet-occupied Germany, Stalin instituted the Berlin Blockade on 24 June 1948, preventing food, materials and supplies from arriving in West Berlin . The blockade

880-762: A member of the Comecon or the Warsaw Pact. Parting with the USSR in 1948, Yugoslavia did not belong to the East, but it also did not belong to the West because of its socialist system and its status as a founding member of the Non-Aligned Movement . However, some sources consider Yugoslavia to be a member of the Eastern Bloc. Others consider Yugoslavia not to be a member after it broke with Soviet policy in

968-441: A mid-air collision between the two ejector seats. During their late life, many L-29s were resold onto private operators and have seen use in the civil sector. It has become common for various modifications to be carried out to convert the type for such use; these changes would commonly include the removal of military-orientated equipment (such as the gun sight ), the replacement of the metric altimeters with Western counterparts,

1056-561: A modification of Western " bourgeois democracy ". As a young communist was told in East Germany, "it's got to look democratic, but we must have everything in our control". Stalin felt that socioeconomic transformation was indispensable to establish Soviet control, reflecting the Marxist–Leninist view that material bases, the distribution of the means of production, shaped social and political relations. The Soviet Union also co-opted

1144-419: A potential threat because of the bases underlying Communist power therein. The suppression of dissidence and opposition was considered a central prerequisite to retain power, though the enormous expense at which the population in certain countries were kept under secret surveillance may not have been rational. Following a totalitarian initial phase, a post-totalitarian period followed the death of Stalin in which

1232-408: A public relations campaign against the western policy change and communists attempted to disrupt the elections of 1948 preceding large losses therein, while 300,000 Berliners demonstrated and urged the international airlift to continue. In May 1949, Stalin lifted the blockade, permitting the resumption of Western shipments to Berlin. After disagreements between Yugoslav leader Josip Broz Tito and

1320-510: A unified Soviet command structure. Beginning in 1964, Romania took a more independent course. While it did not repudiate either Comecon or the Warsaw Pact, it ceased to play a significant role in either. Nicolae Ceaușescu 's assumption of leadership one year later pushed Romania even further in the direction of separateness. Albania, which had become increasingly isolated under Stalinist leader Enver Hoxha following de-Stalinization , undergoing an Albanian–Soviet split in 1961, withdrew from

1408-564: A world of democracy and peace". While meeting with Stalin and Roosevelt in Tehran in 1943, Churchill stated that Britain was vitally interested in restoring Poland as a politically independent country. Britain did not press the matter for fear that it would become a source of inter-allied friction. In February 1945, at the conference at Yalta , Stalin demanded a Soviet sphere of political influence in Central Europe. Stalin eventually

1496-403: Is a jet-powered trainer aircraft, known for its straightforward and simplistic design and construction. In terms of its basic configuration, it used a mid-wing matched with a T-tail arrangement; the wings were unswept and accommodated air intakes for the engines within the wing roots . The undercarriage was reinforced and capable of withstanding considerable stresses. According to Fredriksen,

1584-543: Is replaced by a socialist encirclement". In 1939, the USSR entered into the Molotov–Ribbentrop Pact with Nazi Germany that contained a secret protocol that divided Romania, Poland, Latvia, Lithuania, Estonia and Finland into German and Soviet spheres of influence. Eastern Poland, Latvia, Estonia, Finland and Bessarabia in northern Romania were recognized as parts of the Soviet sphere of influence . Lithuania

1672-512: The 2008 South Ossetia war . On 18 January 2015, separatist forces in the War in Donbass claimed that they possessed an operational L-29. Data from Jane's All The World's Aircraft 1971–72 General characteristics Performance Armament Related development Aircraft of comparable role, configuration, and era Eastern Bloc The Eastern Bloc , also known as

1760-519: The Comecon ( East Germany , Poland , Czechoslovakia , Hungary , Romania , Bulgaria , and Albania ). In Asia , the Eastern Bloc comprised Mongolia , Vietnam , Laos , Kampuchea , North Korea , South Yemen , Syria , and China . In the Americas , the countries aligned with the Soviet Union included Cuba from 1961 and for limited periods Nicaragua and Grenada . The term Eastern Bloc

1848-538: The Comecon in accordance with Stalin's desire to enforce Soviet domination of the lesser states of Central Europe and to mollify some states that had expressed interest in the Marshall Plan , and which were now, increasingly, cut off from their traditional markets and suppliers in Western Europe. The Comecon's role became ambiguous because Stalin preferred more direct links with other party chiefs than

1936-792: The Communist Bloc ( Combloc ), the Socialist Bloc , and the Soviet Bloc , was the collective term for an unofficial coalition of communist states of Central and Eastern Europe , Asia , Africa , and Latin America that were aligned with the Soviet Union and existed during the Cold War (1947–1991). These states followed the ideology of Marxism–Leninism , in opposition to the capitalist Western Bloc . The Eastern Bloc

2024-673: The L-29A Akrobat . Another model, an armed reconnaissance version complete with multiple downwards-looking cameras installed in the rear cockpit position, referred to as the L-29R , was also under development; however, during 1965, the L-29R project was terminated. Optional armaments could be installed upon some models, consisting of either a detachable gun pod or a pod containing up to four unguided missiles , which could be set upon hardpoints underneath each wing. The Aero L-29 Delfín

2112-610: The Ogaden War in 1977. Although not Marxist–Leninist , leadership of Ba'athist Syria officially regarded the country as part of the Socialist Bloc and established a close economic, military alliance with the Soviet Union. Many states were accused by the Western Bloc of being in the Eastern Bloc when they were part of the Non-Aligned Movement . The most limited definition of the Eastern Bloc would only include

2200-646: The Soviets occupied the territories . In June 1941, Germany broke the Molotov-Ribbentrop pact by invading the Soviet Union . From the time of this invasion to 1944, the areas annexed by the Soviet Union were part of Germany's Ostland (except for the Moldavian SSR ). Thereafter, the Soviet Union began to push German forces westward through a series of battles on the Eastern Front . In

2288-681: The Warsaw Pact was formed partly in response to NATO 's inclusion of West Germany and partly because the Soviets needed an excuse to retain Red Army units in Hungary. For 35 years, the Pact perpetuated the Stalinist concept of Soviet national security based on imperial expansion and control over satellite regimes in Eastern Europe. This Soviet formalization of their security relationships in

2376-851: The 1948 Tito–Stalin split . In 1922, the Russian SFSR , the Ukrainian SSR , the Byelorussian SSR and the Transcaucasian SFSR approved the Treaty of Creation of the USSR and the Declaration of the Creation of the USSR, forming the Soviet Union . Soviet leader Joseph Stalin , who viewed the Soviet Union as a "socialist island", stated that the Soviet Union must see that "the present capitalist encirclement

2464-483: The Bloc were instructed to foster intra-leadership conflict and to transmit information against each other. This accompanied a continuous stream of accusations of "nationalistic deviations", "insufficient appreciation of the USSR's role", links with Tito and "espionage for Yugoslavia". This resulted in the persecution of many major party cadres, including those in East Germany. The first country to experience this approach

2552-573: The British Armstrong Siddeley Viper turbojet engine. From 10 September to 14 September 2008, a pair of L-29s took first and second place at the Reno Air Races . Both L-29s consistently posted laps at or above 500 miles per hour; former Astronaut Curt Brown took first place in "Viper," followed by Red Bull racer Mike Mangold in "Euroburner." Russia has claimed that it destroyed a pair of Georgian L-29s during

2640-434: The Comecon's indirect sophistication; it played no significant role in the 1950s in economic planning. Initially, the Comecon served as cover for the Soviet taking of materials and equipment from the rest of the Eastern Bloc, but the balance changed when the Soviets became net subsidizers of the rest of the Bloc by the 1970s via an exchange of low cost raw materials in return for shoddily manufactured finished goods. In 1955,

2728-484: The Delfín programme. The student pilot and their instructor were placed in a tandem seating layout underneath separate canopies , the instructor being placed in a slightly elevated position to better oversee the student. Both the student and instructor were provisioned with ejection seats ; these were intentionally interlinked to fire in a synchronised manner if either seat was deployed as to eliminate any possibility of

2816-500: The Eastern Bloc reflected Moscow's basic security policy principle that continued presence in East Central Europe was a foundation of its defense against the West. Through its institutional structures, the Pact also compensated in part for the absence of Joseph Stalin's personal leadership since his death in 1953. The Pact consolidated the other Bloc members' armies in which Soviet officers and security agents served under

2904-408: The Eastern Bloc, despite attempts by authorities to jam the airways. Under the state atheism of many Eastern Bloc nations, religion was actively suppressed. Since some of these states tied their ethnic heritage to their national churches, both the peoples and their churches were targeted by the Soviets. In 1949, the Soviet Union , Bulgaria, Czechoslovakia , Hungary, Poland, and Romania founded

2992-863: The Eastern European countries into its sphere of influence by making reference to some cultural commonalities. Moscow-trained cadres were put into crucial power positions to fulfill orders regarding sociopolitical transformation. Elimination of the bourgeoisie 's social and financial power by expropriation of landed and industrial property was accorded absolute priority. These measures were publicly billed as "reforms" rather than socioeconomic transformations. Except for initially in Czechoslovakia, activities by political parties had to adhere to "Bloc politics", with parties eventually having to accept membership in an "antifascist bloc" obliging them to act only by mutual "consensus". The bloc system permitted

3080-744: The Geneva Convention of 1951. Most Soviets allowed to leave during this time period were ethnic Jews permitted to emigrate to Israel after a series of embarrassing defections in 1970 caused the Soviets to open very limited ethnic emigrations. The fall of the Iron Curtain was accompanied by a massive rise in European East-West migration. Famous Eastern Bloc defectors included Joseph Stalin's daughter Svetlana Alliluyeva , who denounced Stalin after her 1967 defection. COMECON Too Many Requests If you report this error to

3168-611: The L-29 functioned as a relatively good ground-attack aircraft when deployed as such. It saw several uses in this active combat role, such as when a number of Egyptian L-29s were dispatched on attack missions against Israeli ground forces during the Yom Kippur War of 1973. The type was also used in anger during the Nigerian Civil War of the late 1960s. On 16 July 1975, a Czechoslovak Air Force L-29 reportedly shot down

3256-659: The L-29 was relatively underpowered, yet exhibited several favourable characteristics in its flight performance, such as its ease of handling. The primary flying controls are manually operated; both the flaps and airbrakes were actuated via hydraulic systems. Production aircraft were powered by the Czech-designed Motorlet M-701 turbojet engine, which was capable of generating up to 1,960lbf of thrust. Between 1961 and 1968, approximately 9,250 engines were completed; according to reports, no fewer than 5,000 of these engines were manufactured in support of

3344-720: The Polish rejection of the Plan with a huge 5-year trade agreement, including $ 450 million in credit, 200,000 tons of grain, heavy machinery and factories. In July 1947, Stalin ordered these countries to pull out of the Paris Conference on the European Recovery Programme, which has been described as "the moment of truth" in the post- World War II division of Europe. Thereafter, Stalin sought stronger control over other Eastern Bloc countries, abandoning

3432-670: The Soviet Union regarding Greece and Albania , a Tito–Stalin split occurred, followed by Yugoslavia being expelled from the Cominform in June 1948 and a brief failed Soviet putsch in Belgrade. The split created two separate communist forces in Europe. A vehement campaign against Titoism was immediately started in the Eastern Bloc, describing agents of both the West and Tito in all places as engaging in subversive activity. Stalin ordered

3520-478: The Soviet Union to exercise domestic control indirectly. Crucial departments such as those responsible for personnel, general police, secret police and youth were strictly Communist run. Moscow cadres distinguished "progressive forces" from "reactionary elements" and rendered both powerless. Such procedures were repeated until Communists had gained unlimited power and only politicians who were unconditionally supportive of Soviet policy remained. In June 1947, after

3608-483: The Soviet Union, where it was used as the standard trainer for the Soviet Air Force . Of the others, which included both armed and unarmed models, many aircraft were delivered to the various COMECON countries while others were exported to various overseas nations, including Egypt , Syria , Indonesia , Nigeria and Uganda . Reportedly, the L-29 has been used in active combat during several instances, perhaps

3696-511: The Soviets had refused to negotiate a potential lightening of restrictions on German development, the United States announced the Marshall Plan , a comprehensive program of American assistance to all European countries wanting to participate, including the Soviet Union and those of Eastern Europe. The Soviets rejected the Plan and took a hard-line position against the United States and non-communist European nations. However, Czechoslovakia

3784-462: The TS-11; however, all of the other Warsaw Pact countries decided to adopt the Delfín under the agreements of COMECON . During April 1963, full-scale production of the L-29 commenced; 3,600 aircraft were manufactured over a production run of 11 years. During its production life, several derivatives of the L-29 were developed, such as a dedicated, single-seat, aerobatic version, which was designated as

3872-504: The Warsaw Pact in 1968 following the Warsaw Pact invasion of Czechoslovakia . In 1917, Russia restricted emigration by instituting passport controls and forbidding the exit of belligerent nationals. In 1922, after the Treaty on the Creation of the USSR , both the Ukrainian SSR and the Russian SFSR issued general rules for travel that foreclosed virtually all departures, making legal emigration impossible. Border controls thereafter strengthened such that, by 1928, even illegal departure

3960-503: The Warsaw Pact states and the Mongolian People's Republic as former satellite states most dominated by the Soviet Union. Cuba 's defiance of complete Soviet control was noteworthy enough that Cuba was sometimes excluded as a satellite state altogether, as it sometimes intervened in other Third World countries even when the Soviet Union opposed this. Post-1991 usage of the term "Eastern Bloc" may be more limited in referring to

4048-407: The West and Tito. Despite the initial institutional design of communism implemented by Joseph Stalin in the Eastern Bloc, subsequent development varied across countries. In satellite states, after peace treaties were initially concluded, opposition was essentially liquidated, fundamental steps towards socialism were enforced, and Kremlin leaders sought to strengthen control therein. Right from

4136-789: The addition of alternative radio systems, and new ejection seats. It was also routine for several subsystems, such as the oxygen system, to be disabled rather than removed. In excess of 2,000 L-29 Delfins were ultimately supplied to the Soviet Air Force. Like the majority of Soviet-operated aircraft, it acquired its own NATO reporting name, "Maya." In the trainer role, the L-29 enabled air forces to adopt an "all-through" training regime using only jet-powered aircraft, entirely replacing earlier piston-engined types. The Delfín served in basic, intermediate and weapons training roles. For this latter mission, they were equipped with hardpoints to carry gunpods, bombs or rockets; according to Fredrikson,

4224-587: The aftermath of World War II on the Soviet-Finnish border , the parties signed another peace treaty ceding to the Soviet Union in 1944, followed by a Soviet annexation of roughly the same eastern Finnish territories as those of the prior interim peace treaty as part of the Karelo-Finnish Soviet Socialist Republic . From 1943 to 1945, several conferences regarding Post-War Europe occurred that, in part, addressed

4312-455: The beginning, Stalin directed systems that rejected Western institutional characteristics of market economies , capitalist parliamentary democracy (dubbed "bourgeois democracy" in Soviet parlance) and the rule of law subduing discretional intervention by the state. The resulting states aspired to total control of a political center backed by an extensive and active repressive apparatus, and a central role of Marxist–Leninist ideology. However,

4400-470: The conversion of the Cominform into an instrument to monitor and control the internal affairs of other Eastern Bloc parties. He also briefly considered converting the Cominform into an instrument for sentencing high-ranking deviators, but dropped the idea as impractical. Instead, a move to weaken communist party leaders through conflict was started. Soviet cadres in communist party and state positions in

4488-462: The core of the system, with their names becoming synonymous with raw power and the threat of violent retribution should an individual become active against the State. Several state police and secret police organizations enforced communist party rule, including the following: The press in the communist period was an organ of the state, completely reliant on and subservient to the communist party. Before

4576-594: The country's population who had accepted total obedience. Those who secured membership in this selective group received considerable rewards, such as access to special lower priced shops with a greater selection of high-quality domestic and/or foreign goods ( confections , alcohol , cigars , cameras , televisions , and the like), special schools, holiday facilities, homes, high-quality domestic and/or foreign-made furniture, works of art, pensions, permission to travel abroad, and official cars with distinct license plates so that police and others could identify these members from

4664-500: The development process, leading to the adoption of manual flight controls, large flaps , and the incorporation of perforated airbrakes positioned on the fuselage sides. Aerodynamically, the L-29 was intentionally designed to possess stable and docile flight characteristics; this decision contributed to an enviable safety record for the type. The sturdy L-29 was able to operate under austere conditions, including performing take-offs from grass, sand or unprepared fields . On 5 April 1959,

4752-482: The effort was headed by a pair of aerospace engineers, Z. Rublič and K. Tomáš. Their work was centered upon the desire to produce a single design that would be suitable both performing basic and advanced levels of the training regime, carrying pilots straight through to being prepared to operate frontline combat aircraft. The basic design concept was to produce a straightforward, easy-to-build and operate aircraft. Accordingly, both simplicity and ruggedness were stressed in

4840-725: The end of the Cold War: the People's Democratic Republic of Yemen (from 1967), the People's Republic of the Congo (from 1969), the People's Republic of Benin , the People's Republic of Angola and People's Republic of Mozambique from 1975, the People's Revolutionary Government of Grenada from 1979 to 1983, the Derg / People's Democratic Republic of Ethiopia from 1974, and the Somali Democratic Republic from 1969 until

4928-495: The form of government under which they will live". The parties also agreed to help those countries form interim governments "pledged to the earliest possible establishment through free elections" and "facilitate where necessary the holding of such elections". At the beginning of the July–August 1945 Potsdam Conference after Germany's unconditional surrender, Stalin repeated previous promises to Churchill that he would refrain from

5016-503: The former believing Soviet leader Stalin to be a "devil"-like tyrant leading a vile system. When warned of potential domination by a Stalin dictatorship over part of Europe, Roosevelt responded with a statement summarizing his rationale for relations with Stalin: "I just have a hunch that Stalin is not that kind of a man. ... I think that if I give him everything I possibly can and ask for nothing from him in return, noblesse oblige, he won't try to annex anything and will work with me for

5104-470: The future structure of the "Polish region". Soviet authorities immediately started a campaign of sovietization of the newly Soviet-annexed areas . Soviet authorities collectivized agriculture, and nationalized and redistributed private and state-owned Polish property. Initial Soviet occupations of the Baltic countries had occurred in mid-June 1940, when Soviet NKVD troops raided border posts in Lithuania , Estonia and Latvia , followed by

5192-418: The goal of developing a trainer aircraft that could be adopted and in widespread use throughout the national air forces of the Eastern Bloc countries. Around the same time, Czechoslovakia had also been independently developing its own requirements for a suitable jet successor to its then-current propeller-powered trainer aircraft. In response to these demands, Aero decided to develop its own aircraft design;

5280-419: The late 1980s, Eastern Bloc radio and television organizations were state-owned, while print media was usually owned by political organizations, mostly by the local communist party. Youth newspapers and magazines were owned by youth organizations affiliated with communist parties. The control of the media was exercised directly by the communist party itself, and by state censorship, which was also controlled by

5368-416: The liquidation of state administrations and replacement by Soviet cadres. Elections for parliament and other offices were held with single candidates listed and the official results fabricated, purporting pro-Soviet candidates' approval by 92.8 percent of the voters in Estonia, 97.6 percent in Latvia, and 99.2 percent in Lithuania. The fraudulently installed "people's assemblies" immediately declared each of

5456-404: The main rival submissions for the Warsaw Pact 's standardised trainer. Shortly after the completion of the fly-offs, it was announced that the L-29 had been selected as the winner; according to aviation author John C. Fredrikson, this outcome had been highly unexpected and surprising to several observers. Regardless of the result, Poland chose to continue to pursue the development and procurement of

5544-409: The most high-profile being the use of Nigerian aircraft during the Nigerian Civil War of the late 1960s and of Egyptian L-29s against Israeli tanks during the brief Yom Kippur War of 1973. In the late 1950s, the Soviet Air Force commenced the search for a suitable jet-powered replacement for its fleet of piston-engined trainers; over time, this requirement was progressively broadened towards

5632-446: The parties entered into an interim peace treaty granting the Soviet Union a portion of the eastern region of Karelia (10% of Finnish territory), and the Karelo-Finnish Soviet Socialist Republic was established by merging the ceded territories with the KASSR . After a June 1940 Soviet Ultimatum demanding Bessarabia, Bukovina , and the Hertsa region from Romania, the Soviets entered these areas, Romania caved to Soviet demands and

5720-525: The party. Media served as an important form of control over information and society. The dissemination and portrayal of knowledge were considered by authorities to be vital to communism's survival by stifling alternative concepts and critiques. Several state Communist Party newspapers were published, including: The Telegraph Agency of the Soviet Union (TASS) served as the central agency for collection and distribution of internal and international news for all Soviet newspapers, radio and television stations. It

5808-517: The potential Soviet annexation and control of countries in Central Europe. There were various Allied plans for state order in Central Europe for post-war. While Joseph Stalin tried to get as many states under Soviet control as possible, British Prime Minister Winston Churchill preferred a Central European Danube Confederation to counter these countries against Germany and Russia. Churchill's Soviet policy regarding Central Europe differed vastly from that of American President Franklin D. Roosevelt , with

5896-413: The power of the local Communist elites. The port city of Trieste was a particular focus after the Second World War. Until the break between Tito and Stalin, the Western powers and the Eastern bloc faced each other uncompromisingly. The neutral buffer state Free Territory of Trieste , founded in 1947 with the United Nations, was split up and dissolved in 1954 and 1975, also because of the détente between

5984-401: The primary method of Communist rule shifted from mass terror to selective repression, along with ideological and sociopolitical strategies of legitimation and the securing of loyalty. Juries were replaced by a tribunal of professional judges and two lay assessors that were dependable party actors. The police deterred and contained opposition to party directives. The political police served as

6072-417: The prior appearance of democratic institutions. When it appeared that, in spite of heavy pressure, non-communist parties might receive in excess of 40% of the vote in the August 1947 Hungarian elections , repressions were instituted to liquidate any independent political forces. In that same month, annihilation of the opposition in Bulgaria began on the basis of continuing instructions by Soviet cadres. At

6160-425: The prototype XL-29 conducted its maiden flight , powered by a British Bristol Siddeley Viper turbojet engine. The second prototype, which flew shortly thereafter, was instead powered by the Czech-designed M701 engine. The M-701 engine was used in all subsequent aircraft. During 1961, a small pre-production batch of L-29s were evaluated against the Polish PZL TS-11 Iskra and the Russian Yakovlev Yak-30 ,

6248-479: The sharp 1953 increase was fear of potential further Sovietization with the increasingly paranoid actions of Joseph Stalin in late 1952 and early 1953. 226,000 had fled in just the first six months of 1953. With the closing of the Inner German border officially in 1952, the Berlin city sector borders remained considerably more accessible than the rest of the border because of their administration by all four occupying powers. Accordingly, it effectively comprised

6336-399: The states forming the Warsaw Pact (1955–1991) and Mongolia (1924–1991), which are no longer communist states. Sometimes they are more generally referred to as "the countries of Eastern Europe under communism", excluding Mongolia, but including Yugoslavia and Albania which had both split with the Soviet Union by the 1960s. Even though Yugoslavia was a socialist country, it was not

6424-413: The substitution of autonomous law. Initially, communist parties were small in all countries except Czechoslovakia, such that there existed an acute shortage of politically "trustworthy" persons for administration, police, and other professions. Thus, "politically unreliable" non-communists initially had to fill such roles. Those not obedient to communist authorities were ousted, while Moscow cadres started

6512-499: The three corresponding countries to be "Soviet Socialist Republics" and requested their "admission into Stalin 's Soviet Union". This formally resulted in the Soviet Union's annexation of Lithuania, Latvia, and Estonia in August 1940. The international community condemned this annexation of the three Baltic countries and deemed it illegal. In 1939, the Soviet Union unsuccessfully attempted an invasion of Finland , subsequent to which

6600-692: The total inventory of 18 L-29s; the Azeri Air Force lost large amounts of its air force due to anti aircraft fire. On 2 October 2007, an unmodified L-29 was used for the world's first jet flight powered solely by 100 per cent biodiesel fuel. Pilots Carol Sugars and Douglas Rodante flew their Delphin Jet from Stead Airport , Reno, Nevada to Leesburg International Airport , Leesburg, Florida in order to promote environmentally friendly fuels in aviation. The L-29, much like its L-39 successor, has found use in air racing, some of which have been re-engined with

6688-442: The vestiges of democratic institutions were never entirely destroyed, resulting in the façade of Western style institutions such as parliaments, which effectively just rubber-stamped decisions made by rulers, and constitutions, to which adherence by authorities was limited or non-existent. Parliaments were still elected, but their meetings occurred only a few days per year, only to legitimize politburo decisions, and so little attention

6776-477: Was Albania , where leader Enver Hoxha immediately changed course from favoring Yugoslavia to opposing it. In Poland , leader Władysław Gomułka , who had previously made pro-Yugoslav statements, was deposed as party secretary-general in early September 1948 and subsequently jailed. In Bulgaria , when it appeared that Traicho Kostov, who was not a Moscow cadre, was next in line for leadership, in June 1949, Stalin ordered Kostov's arrest, followed soon thereafter by

6864-589: Was added in a second secret protocol in September 1939. The Soviet Union had invaded the portions of eastern Poland assigned to it by the Molotov–Ribbentrop Pact two weeks after the German invasion of western Poland, followed by co-ordination with German forces in Poland. During the Occupation of East Poland by the Soviet Union , the Soviets liquidated the Polish state, and a German-Soviet meeting addressed

6952-634: Was caused, in part, by early local elections of October 1946 in which the Socialist Unity Party of Germany (SED) was rejected in favor of the Social Democratic Party, which had gained two and a half times more votes than the SED. The United States, Britain, France, Canada, Australia, New Zealand and several other countries began a massive "Berlin airlift", supplying West Berlin with food and other supplies. The Soviets mounted

7040-421: Was convinced by Churchill and Roosevelt not to dismember Germany. Stalin stated that the Soviet Union would keep the territory of eastern Poland they had already taken via invasion in 1939 with some exceptions , and wanted a pro-Soviet Polish government in power in what would remain of Poland. After resistance by Churchill and Roosevelt, Stalin promised a re-organization of the current pro-Soviet government on

7128-493: Was delivered from the 1960s onwards. During the early 1970s, the type was succeeded in the principal trainer role by another Aero-built aircraft, the L-39 Albatros , heavily contributing to a decline in demand for the earlier L-29 and the end of its production during 1974. During the course of the programme, in excess of 3,000 L-29 Delfín trainers were produced. Of these, around 2,000 were reported to have been delivered to

7216-521: Was eager to accept the US aid; the Polish government had a similar attitude, and this was of great concern to the Soviets. In one of the clearest signs of Soviet control over the region up to that point, the Czechoslovakian foreign minister, Jan Masaryk , was summoned to Moscow and berated by Stalin for considering joining the Marshall Plan. Polish Prime minister Józef Cyrankiewicz was rewarded for

7304-523: Was effectively halted in the early 1950s, with the Soviet approach to controlling national movement emulated by most of the rest of the Eastern Bloc. However, in East Germany , taking advantage of the Inner German border between occupied zones, hundreds of thousands fled to West Germany, with figures totaling 197,000 in 1950, 165,000 in 1951, 182,000 in 1952 and 331,000 in 1953. One reason for

7392-444: Was effectively impossible. This later included internal passport controls , which when combined with individual city Propiska ("place of residence") permits, and internal freedom of movement restrictions often called the 101st kilometre , greatly restricted mobility within even small areas of the Soviet Union. After the creation of the Eastern Bloc, emigration out of the newly occupied countries, except under limited circumstances,

7480-582: Was frequently infiltrated by Soviet intelligence and security agencies, such as the NKVD and GRU . TASS had affiliates in 14 Soviet republics, including the Lithuanian SSR , Latvian SSR , Estonian SSR , Moldavian SSR . Ukrainian SSR and Byelorussian SSR . Western countries invested heavily in powerful transmitters which enabled services such as the BBC , VOA and Radio Free Europe (RFE) to be heard in

7568-541: Was often called the " Second World ", whereas the term " First World " referred to the Western Bloc and " Third World " referred to the non-aligned countries that were mainly in Africa, Asia, and Latin America but notably also included former pre-1948 Soviet ally Yugoslavia , which was located in Europe. In Western Europe , the term Eastern Bloc generally referred to the USSR and Central and Eastern European countries in

7656-608: Was often used interchangeably with the term Second World . This broadest usage of the term would include not only Maoist China and Cambodia , but also short-lived Soviet satellites such as the Second East Turkestan Republic (1944–1949), the People's Republic of Azerbaijan (1945–1946) and the Republic of Mahabad (1946), as well as the Marxist–Leninist states straddling the Second and Third Worlds before

7744-460: Was paid to them that some of those serving were actually dead, and officials would openly state that they would seat members who had lost elections. The first or General Secretary of the central committee in each communist party was the most powerful figure in each regime. The party over which the politburo held sway was not a mass party but, conforming with Leninist tradition, a smaller selective party of between three and fourteen percent of
