Fall of Communism in the context of "Removal of Hungary's border fence with Austria"

The Bulgarian Army (Bulgarian: Българска армия, romanized: Bŭlgarska armiya), also called Bulgarian Armed Forces (Bulgarian: Български Въоръжени сили, romanized: Bŭlgarski Vŭorŭzheni Sili), is the military of Bulgaria. The commander-in-chief is the president of Bulgaria. The Ministry of Defense is responsible for political leadership, while overall military command is in the hands of the Defense Staff, headed by the Chief of the Defense. There are three main branches of the Bulgarian military, named literally the Land Forces, the Air Forces and the Naval Forces (the term "Bulgarian Army" refers to them encompassed all together).

Throughout history, the Army has played a major role in defending the country's sovereignty. Only several years after its inception in 1878, Bulgaria became a regional military power and was involved in several major wars – Serbo-Bulgarian War (1885), First Balkan War (1912–13), Second Balkan War (1913), First World War (1915–1918) and Second World War (1941–1945), during which the Army gained considerable combat experience. During the Cold War, the People's Republic of Bulgaria maintained one of the largest militaries in the Warsaw Pact, numbering an estimated 152,000 troops in 1988. Since the Fall of Communism, the political leadership has decided to pursue a pro-NATO policy, thus reducing military personnel and weaponry. Bulgaria joined the North Atlantic Treaty Organization on 29 March 2004.

Soviet dissidents were people who disagreed with certain features of Soviet ideology or with its entirety and who were willing to speak out against them. The term dissident was used in the Soviet Union (USSR) in the period from the mid-1960s until the Fall of Communism. It was used to refer to small groups of marginalized intellectuals whose challenges, from modest to radical to the Soviet regime, met protection and encouragement from correspondents, and typically criminal prosecution or other forms of silencing by the authorities. Following the etymology of the term, a dissident is considered to "sit apart" from the regime. As dissenters began self-identifying as dissidents, the term came to refer to an individual whose non-conformism was perceived to be for the good of a society. The most influential subset of the dissidents is known as the Soviet human rights movement.

Political opposition in the USSR was barely visible, and apart from rare exceptions, it had little consequence, primarily because it was instantly crushed with brute force. Instead, an important element of dissident activity in the Soviet Union was informing society (both inside the USSR and in foreign countries) about violation of laws and human rights and organizing in defense of those rights. Over time, the dissident movement created vivid awareness of Soviet Communist abuses.
