Background: Kwon Bo-ah (Korean: gweonboa, born November 5, 1986), known professionally as BoA, is a South Korean singer, dancer, composer and actress active in South Korea and Japan. She is referred to as the Queen of Korean Pop. Born and raised in Gyeonggi-do, South Korea, she was discovered by SM Entertainment talent agents when she accompanied her older brother to a talent search.
Context: BoA's second Japanese studio album, Valenti (2003), became her best-selling album, with over 1,249,000 copies sold. In support of the album, BoA launched BoA 1st Live Tour Valenti, her first Japanese concert tour. Later that year, she released two Korean albums, Atlantis Princess and the mini-album Shine We Are!. The former was the fifth-best-selling South Korean record of the year with around 345,000 units sold; the latter sold around 58,000 units. Her third Japanese studio album, Love & Honesty (2004) was a musical "change in direction": it contained a rock-dance song ("Rock with You") and "harder" R&B. Though the album failed to match Valenti in sales, it topped the Oricon chart for two weeks and became RIAJ-certified triple-platinum. In support of the album, BoA held a tour, Live Concert Tour 2004: Love & Honesty. In contrast with 1st Live Tour, which "emphasized exotic Asian design", the Love & Honesty tour had an "outer-space, sci-fi" theme; among the props were a three-story-high space ship and the robot Asimo. The tour, which started in Saitama and ended in Yokohama, spanned nine performances and attracted approximately 105,000 attendants. Her first compilation album, Best of Soul (2005), however, sold over a million copies, making BoA the first non-Japanese Asian singer to have two million-selling albums in Japan. BoA reinvented her image on her fourth Korean album, My Name (2004); she left the "cute" and "youthful" style that had characterized previous years and presented herself as "sexy" and "sultry". The album was the beginning of a foray into the Chinese market and contained two songs sung in Mandarin Chinese. The sales of BoA's Korean albums began to decline: the album sold 191,000 units and became the eleventh-best-selling South Korean album of the year. In September 2004, BoA instigated controversy in Japan when she donated W50 million to a memorial project for Korean independence activist and nationalist An Jung-geun. Her fifth Korean album, Girls on Top (2005), continued her image change. The album portrayed the singer as more "mature and self-confident" and was a "declaration of war on male chauvinism"; the "bohemian" look of the cover photograph represented "freedom and depth", while music videos and album photographs that portrayed BoA in traditional Korean dress brought the "idea of Korean womanhood" into her music. The album also continued BoA's foray into the Chinese market and, like the previous album, contained Mandarin Chinese songs. The album sold less than the previous album; it was the fourteenth-best-selling record of the year in South Korea with 113,000 units sold.

Background: The Aztecs (), were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521, during the time in which a triple alliance of the Mexica, Texcoca and Tepaneca tribes established the Aztec empire. The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture is the culture of the people referred to as Aztecs, but since most ethnic groups of central Mexico in the postclassic period shared basic cultural traits, many of the traits that characterize Aztec culture cannot be said to be exclusive to the Aztecs. For the same reason, the notion of "Aztec civilization" is best understood as a particular horizon of a general Mesoamerican civilization.
Context: The Nahuatl words aztecatl [as'tekatl] (singular) and aztecah [as'teka?] (plural) mean "people from Aztlan", a mythological place for the Nahuatl-speaking culture of the time, and later adopted as the word to define the Mexica people. Often the term "Aztec" refers exclusively to the Mexica people of Tenochtitlan (now the location of Mexico City), situated on an island in Lake Texcoco, who referred to themselves as Mexihcah Tenochcah [me:'Si?ka? te'notSka?] or Colhuah Mexihcah ['ko:lwa? me:'Si?ka?]. Sometimes the term also includes the inhabitants of Tenochtitlan's two principal allied city-states, the Acolhuas of Texcoco and the Tepanecs of Tlacopan, who together with the Mexica formed the Aztec Triple Alliance that controlled what is often known as the "Aztec Empire". In other contexts, Aztec may refer to all the various city states and their peoples, who shared large parts of their ethnic history and cultural traits with the Mexica, Acolhua and Tepanecs, and who often also used the Nahuatl language as a lingua franca. In this meaning, it is possible to talk about an Aztec civilization including all the particular cultural patterns common for most of the peoples inhabiting central Mexico in the late postclassic period. When used to describe ethnic groups, the term "Aztec" refers to several Nahuatl-speaking peoples of central Mexico in the postclassic period of Mesoamerican chronology, especially the Mexica, the ethnic group that had a leading role in establishing the hegemonic empire based at Tenochtitlan. The term extends to further ethnic groups associated with the Aztec empire, such as the Acolhua, the Tepanec and others that were incorporated into the empire. In older usage the term was commonly used about modern Nahuatl-speaking ethnic groups, as Nahuatl was previously referred to as the "Aztec language". In recent usage, these ethnic groups are referred to as the Nahua peoples. Linguistically, the term "Aztecan" is still used about the branch of the Uto-Aztecan languages (also sometimes called the yuto-nahuan languages) that includes the Nahuatl language and its closest relatives Pochutec and Pipil. To the Aztecs themselves the word "aztec" was not an endonym for any particular ethnic group. Rather, it was an umbrella term used to refer to several ethnic groups, not all of them Nahuatl-speaking, that claimed heritage from the mythic place of origin, Aztlan. In the Nahuatl language "aztecatl" means "person from Aztlan". Alexander von Humboldt originated the modern usage of "Aztec" in 1810, as a collective term applied to all the people linked by trade, custom, religion, and language to the Mexica state and the Triple Alliance. In 1843, with the publication of the work of William H. Prescott, the term was adopted by most of the world, including 19th-century Mexican scholars who saw it as a way to distinguish present-day Mexicans from pre-conquest Mexicans. This usage has been the subject of debate in more recent years, but the term "Aztec" is still more common.
