Question: About how many millions of people lived in the continent the first leg of Queen's mid 2000s tour with Electric's performer took place in year 1000?

full_context: Document 1: Middle Ages: The High Middle Ages was a period of tremendous expansion of population. The estimated population of Europe grew from 35 to 80 million between 1000 and 1347, although the exact causes remain unclear: improved agricultural techniques, the decline of slaveholding, a more clement climate and the lack of invasion have all been suggested. As much as 90 per cent of the European population remained rural peasants. Many were no longer settled in isolated farms but had gathered into small communities, usually known as manors or villages. These peasants were often subject to noble overlords and owed them rents and other services, in a system known as manorialism. There remained a few free peasants throughout this period and beyond, with more of them in the regions of Southern Europe than in the north. The practice of assarting, or bringing new lands into production by offering incentives to the peasants who settled them, also contributed to the expansion of population.
Document 2: Queen (band): In May 2011, Jane's Addiction vocalist Perry Farrell noted that Queen are currently scouting their once former and current live bassist Chris Chaney to join the band. Farrell stated: "I have to keep Chris away from Queen, who want him and they're not gonna get him unless we're not doing anything. Then they can have him." In the same month, Paul Rodgers stated he may tour with Queen again in the near future. At the 2011 Broadcast Music, Incorporated (BMI) Awards held in London on 4 October, Queen received the BMI Icon Award in recognition for their airplay success in the US. At the 2011 MTV Europe Music Awards on 6 November, Queen received the Global Icon Award, which Katy Perry presented to Brian May. Queen closed the awards ceremony, with Adam Lambert on vocals, performing "The Show Must Go On", "We Will Rock You" and "We Are the Champions". The collaboration garnered a positive response from both fans and critics, resulting in speculation about future projects together.
Document 3: Late Middle Ages: Around 1300, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it was before the calamities. Along with depopulation came social unrest and endemic warfare. France and England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict in the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was shattered by the Western Schism. Collectively these events are sometimes called the Crisis of the Late Middle Ages.
Document 4: Electric (Paul Rodgers album): Electric (fully as Paul Rodgers Electric according to Paul Rodgers official site) is a studio album by Paul Rodgers of Free and Bad Company fame. It was recorded in 1999 at Lartington Hall Studios near Barnard Castle in the North East of England. Electric was released in 2000 (the Japanese version of 1999 has a bonus track).
Document 5: The Hendrix Set: The Hendrix Set is a live EP by Paul Rodgers of Free and Bad Company fame. Released 2 November 1993, "The Hendrix Set" consists of covers of five of Jimi Hendrix's songs. It was recorded live at Bayfront Park in Miami, Florida on 4 July 1993.
Document 6: Queen (band): Brian May and Roger Taylor performed together at several award ceremonies and charity concerts, sharing vocals with various guest singers. During this time, they were billed as Queen + followed by the guest singer's name. In 1998, the duo appeared at Luciano Pavarotti's benefit concert with May performing "Too Much Love Will Kill You" with Pavarotti, later playing "Radio Ga Ga", "We Will Rock You", and "We Are the Champions" with Zucchero. They again attended and performed at Pavarotti's benefit concert in Modena, Italy in May 2003. Several of the guest singers recorded new versions of Queen's hits under the Queen + name, such as Robbie Williams providing vocals for "We Are the Champions" for the soundtrack of A Knight's Tale (2001).
Document 7: Cut Loose: Cut Loose is the 1983 debut solo album by Paul Rodgers (of Free and Bad Company fame). Unlike his other work, Paul Rodgers plays all the instruments on this album. It was recorded at his house in Kingstone.
Document 8: Queen (band): On 15 August 2006, Brian May confirmed through his website and fan club that Queen + Paul Rodgers would begin producing their first studio album beginning in October, to be recorded at a "secret location". Queen + Paul Rodgers performed at the Nelson Mandela 90th Birthday Tribute held in Hyde Park, London on 27 June 2008, to commemorate Mandela's ninetieth birthday, and again promote awareness of the HIV/AIDS pandemic. The first Queen + Paul Rodgers album, titled The Cosmos Rocks, was released in Europe on 12 September 2008 and in the United States on 28 October 2008. Following the release of the album, the band again went on a tour through Europe, opening on Kharkiv's Freedom Square in front of 350,000 Ukrainian fans. The Kharkiv concert was later released on DVD. The tour then moved to Russia, and the band performed two sold-out shows at the Moscow Arena. Having completed the first leg of its extensive European tour, which saw the band play 15 sold-out dates across nine countries, the UK leg of the tour sold out within 90 minutes of going on sale and included three London dates, the first of which was The O2 on 13 October. The last leg of the tour took place in South America, and included a sold-out concert at the Estadio José Amalfitani, Buenos Aires.
Document 9: Late Middle Ages: Around 1300–1350 the Medieval Warm Period gave way to the Little Ice Age. The colder climate resulted in agricultural crises, the first of which is known as the Great Famine of 1315-1317. The demographic consequences of this famine, however, were not as severe as the plagues that occurred later in the century, particularly the Black Death. Estimates of the death rate caused by this epidemic range from one third to as much as sixty percent. By around 1420, the accumulated effect of recurring plagues and famines had reduced the population of Europe to perhaps no more than a third of what it was a century earlier. The effects of natural disasters were exacerbated by armed conflicts; this was particularly the case in France during the Hundred Years' War.
Document 10: Queen (band): At the end of 2004, May and Taylor announced that they would reunite and return to touring in 2005 with Paul Rodgers (founder and former lead singer of Free and Bad Company). Brian May's website also stated that Rodgers would be "featured with" Queen as "Queen + Paul Rodgers", not replacing Mercury. The retired John Deacon would not be participating. In November 2004, Queen were among the inaugural inductees into the UK Music Hall of Fame, and the award ceremony was the first event at which Rodgers joined May and Taylor as vocalist.
Document 11: Queen (band): Between 2005 and 2006, Queen + Paul Rodgers embarked on a world tour, which was the first time Queen toured since their last tour with Freddie Mercury in 1986. The band's drummer Roger Taylor commented; "We never thought we would tour again, Paul [Rodgers] came along by chance and we seemed to have a chemistry. Paul is just such a great singer. He's not trying to be Freddie." The first leg was in Europe, the second in Japan, and the third in the US in 2006. Queen received the inaugural VH1 Rock Honors at the Mandalay Bay Events Center in Las Vegas, Nevada, on 25 May 2006. The Foo Fighters paid homage to the band in performing "Tie Your Mother Down" to open the ceremony before being joined on stage by May, Taylor, and Paul Rodgers, who played a selection of Queen hits.
Document 12: Early Middle Ages: For almost a thousand years, Rome was the most politically important, richest and largest city in Europe. Around 100 CE, it had a population of about 450,000, and declined to a mere 20,000 during the Early Middle Ages, reducing the sprawling city to groups of inhabited buildings interspersed among large areas of ruins and vegetation.
Document 13: Middle Ages: Strong, royalty-based nation states rose throughout Europe in the Late Middle Ages, particularly in England, France, and the Christian kingdoms of the Iberian Peninsula: Aragon, Castile, and Portugal. The long conflicts of the period strengthened royal control over their kingdoms and were extremely hard on the peasantry. Kings profited from warfare that extended royal legislation and increased the lands they directly controlled. Paying for the wars required that methods of taxation become more effective and efficient, and the rate of taxation often increased. The requirement to obtain the consent of taxpayers allowed representative bodies such as the English Parliament and the French Estates General to gain power and authority.
Document 14: Live: The Loreley Tapes: Live: The Loreley Tapes... is a live album by Paul Rodgers of Free and Bad Company fame. It was recorded at the Rockpalast Open Air Festival, at Loreley, Germany on 8 July 1995 and released in 1996.
