History of Estonia between 1992 - 2017
By the beginning of the Gorbachev era, concern over the cultural survival of the Estonian people had reached a critical point. The ECP remained stable in the early perestroika years but waned in the late 1980s. Other political movements, groupings and parties moved to fill the power vacuum. The first and most important was the Estonian Popular Front, established in April 1988 with its own platform, leadership and broad constituency. The Greens and the dissident-led Estonian National Independence Party soon followed.
The Estonian Sovereignty Declaration was issued on November 16, 1988. By 1989 the political spectrum had widened, and new parties were formed and re-formed almost daily. The republic's Supreme Soviet transformed into an authentic regional lawmaking body. This relatively conservative legislature passed an early declaration of sovereignty; a law on economic independence (May 1989) confirmed by the Supreme Soviet of the Soviet Union that November; a language law making Estonian the official language (January 1989); and local and republic election laws stipulating residency requirements for voting and candidacy (August, November 1989).
In the March 18, 1990 elections for the 105-member Supreme Soviet all residents of Estonia were eligible to participate, including all Soviet-era immigrants from the U.S.S.R. and approximately 50,000 Soviet troops stationed there. The Popular Front coalition, composed of left and centrist parties and led by former Central Planning Committee official Edgar Savisaar, gained a parliamentary majority.
On May 8, 1990, the Supreme Council of the Republic of Estonia (renamed the previous day) changed the name to the Republic of Estonia. Through a strict, non-confrontational policy in pursuing independence, Estonia managed to avoid the violence which Latvia and Lithuania incurred in the bloody January 1991 crackdowns and in the border customs-post guard murders that summer. During the August coup in the U.S.S.R., Estonia was able to maintain constant operation and control of its telecommunications facilities, thereby offering the West a clear view into the latest coup developments and serving as a conduit for swift Western support and recognition of Estonia's "confirmation" of independence on August 20, 1991. August 20 remains a national holiday in Estonia because of this. Following Europe's lead, the United States formally reestablished diplomatic relations with Estonia on September 2, and the U.S.S.R. Supreme Soviet offered recognition on September 6.
On June 28, 1992, Estonian voters approved the constitutional assembly's draft constitution and implementation act, which established a parliamentary government with a president as chief of state and with a government headed by a prime minister. The Riigikogu, a unicameral legislative body, is the highest organ of state authority. It initiates and approves legislation sponsored by the prime minister. The prime minister has full responsibility and control over his cabinet.
On 14 September 2003, following negotiations that began in 1998, the citizens of Estonia were asked in a referendum whether or not they wished to join the European Union. With 64% of the electorate turning out the referendum passed with a 66.83% margin in favor, 33.17% against. Accession to the EU took place on 1 May of the following year. On 1 January 2011 Estonia adopted the Euro.
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
