Question: How many years had the Russian leader been in power when Russia recognized Baltic independence in September 1991? Passage 1:On 12 May 1990 the leaders of the Baltic republics signed a joint declaration known as the Baltic Entente. By mid-June the Soviets started negotiations with the Baltic republics on condition they agreed to freeze their declarations of independence. The Soviets had a bigger challenge elsewhere, in the form of the Russian Federal Republic proclaiming sovereignty in June. Simultaneously the Baltic republics also started to negotiate directly with the Russian Federal Republic. In Autumn 1990, they set up a customs border between the Baltic states, the Russian Federation and Belarus. After the failed negotiations the Soviets made a dramatic attempt to break the deadlock and sent troops to Lithuania and Latvia in January 1991. The attempts failed, dozens of civilians were killed, and the Soviet troops decided to retreat. In August 1991, the hard-line members of the Soviet government attempted to take control of the Soviet Union. One day after the coup on 21 August, the Estonians proclaimed independence. Shortly afterwards Soviet paratroops seized the Tallinn television tower. The Latvian parliament made similar a declaration at the same day. The coup failed but the Collapse of the Soviet Union became unavoidable. On 28 August, the European Community welcomed the restoration of the sovereignty and independence of the Baltic states. The Soviet Union recognised the Baltic independence on 6 September 1991. The Russian troops stayed for an additional three years, as Boris Yeltsin linked the issue of Russian minorities with troop withdrawals. Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993. On 26 July 1994 Russian troops withdrew from Estonia and on 31 August 1994, Russian troops withdrew from Latvia. The Russian Federation ended its military presence in Estonia after it relinquished control of the nuclear facilities in Paldiski on 26 September 1995 and in Latvia after Skrunda-1 suspended operations on 31 August 1998 and subsequently dismantled. The last Russian soldier left Skrunda-1 in October 1999, thus marking a symbolic end to the Russian military presence on the soil of the Baltic countries.
Passage 2:Nueces is Spanish for "nuts", and refers to the pecan trees that grew along the banks of the Nueces River, noted by Spanish explorer Alonso De Leon in 1689. It is unclear when the name was given to the bay; it was called San Miguel Arcangel by Spanish captain Joaquin de Orobio y Basterra in 1747, and an 1835 map of Texas identified it as Papelote or "wastepaper" Bay. It appears to have been first noted on a Spanish map in 1527 as the mouth of the Rio Escondido or hidden river, which is believed to be the Nueces. French explorer Rene Robert Cavelier, Sieur de La Salle sailed into the bay in 1685, mistakenly believing it was the Mississippi River. Spanish colonial governor Jose de Escandon planned a villa on the mouth of the Nueces River named Villa de Vedoya. Fifty families were sent the site in 1749, but failed to establish a settlement, due to a lack of sufficient supplies. Later that century, missionaries discussed the possibility of moving Nuestra Senora del Refugio Mission to the site, but decided against the idea due to conflict with the Lipan Apaches. Germans attempted to settle the same area, but were turned away by the French during the Pastry War in the 1830s. The next decade, a colony for freed slaves was proposed by abolitionist Benjamin Lundy, who had to cancel after the outbreak of the Texas Revolution.
Passage 3:In 2009 Fertita along with Jack White on drums, Alison Mosshart on lead vocals, and Jack Lawrence on bass formed The Dead Weather. The group originally only intended to record a 7-inch single but plans changed and the band wrote and recorded their debut album in fifteen days. The band's debut album Horehound was released July 14, 2009 and was followed by a supporting tour. In October 2009 lead vocalist Mosshart confirmed that a second album was "halfway done". Later, White revealed in an interview that the band is hoping to have 20 to 25 songs ready for their Australian tour in March 2010. It was later confirmed that the first single from the new album Sea of Cowards would be called "Die by the Drop" which was released March 30. The Sea of Cowards Tour began on March 19, 2010, is ended on August 3, 2010. It included 42 shows over four legs. On September 25, 2015, the Dead Weather released their third studio album Dodge and Burn.
