Switzerland (German: die Schweiz[ˈʃvaɪts]; French: Suisse [sɥis(ə)]; Italian: Svizzera [ˈzvit͡sːɛra]; Romansh: Svizra [ˈʒviːtsrɐ] or [ˈʒviːtsʁːɐ]), in its full name the Swiss Confederation (Latin: Confoederatio Helvetica, hence its abbreviation CH), is a federal republic consisting of 26 cantons, with Bern as the seat of the federal authorities. The country is situated in western Europe, where it is bordered by Germany to the north, France to the west, Italy to the south, and Austria and Liechtenstein to the east.

Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km² (15,940 sq mi). While the Alps occupy the greater part of the territory, the Swiss population of approximately 8 million people is concentrated mostly on the Plateau, where the largest cities are to be found. Among them are the two global cities and economic centres of Zurich and Geneva.

The Swiss Confederation has a long history of armed neutrality—it has not been in a state of war internationally since 1815—and did not join the United Nations until 2002. It pursues, however, an active foreign policy and is frequently involved in peace-building processes around the world. Switzerland is also the birthplace of the Red Cross and home to a large number of international organizations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association and is part of the Schengen Area – although it is notably not a member of the European Union, nor the European Economic Area.

"Cortez the Killer" is a song by Neil Young from his 1975 album, Zuma. It was recorded with Young's band Crazy Horse and ranked #39 on Guitar World's 100 Greatest Guitar Solos and #321 on Rolling Stone's list of the 500 Greatest Songs of All Time.

Young has stated in concert that he wrote the song while studying history in high school in Winnipeg. The song was banned in Spain under Francisco Franco, according to Young's notes for the album Decade. Young's claim is dubious, since Franco was on his death bed on Nov. 10, 1975, the date the song was released. However, this would not necessarily have affected the nature of how the Spanish Censors would have viewed such a song. Franco died on Nov. 20, 1975 after a long illness during which he was incapacitated.

The song is about Hernán Cortez, a conquistador who conquered Mexico for Spain in the 16th century. "Cortez the Killer" also makes reference to the Aztec ruler Moctezuma II and other events that occurred in the Spanish conquest of the New World.

Neil Percival Young,OC,OM (born November 12, 1945) is a Canadian singer-songwriter who is widely regarded as one of the most influential musicians of his generation.

Young began performing as a solo artist in Canada in 1960, before moving to California in 1966, where he co-founded the band Buffalo Springfield along with Stephen Stills and Richie Furay, and later joined Crosby, Stills & Nash as a fourth member in 1969. He forged a successful and acclaimed solo career, releasing his first album in 1968; his career has since spanned over 40 years and 34 studio albums, with a continual and uncompromising exploration of musical styles. The Rock and Roll Hall of Fame website describes Young as "one of rock and roll’s greatest songwriters and performers". He has been inducted into the Hall of Fame twice: first as a solo artist in 1995, and second as a member of Buffalo Springfield in 1997.

Young's work is characterized by his distinctive guitar work, deeply personal lyrics and signature alto or high tenor singing voice. Although he accompanies himself on several different instruments, including piano and harmonica, his idiosyncratic electric and clawhammer acoustic guitar playing are the defining characteristics of a varyingly ragged and melodic sound. While Young has experimented with differing music styles, including swing and electronic music throughout a varied career, his best known work usually falls into two primary styles: acoustic (folk and country rock) and electric (amplified hard rock, very often in collaboration with the band Crazy Horse). Young has also adopted elements from newer styles such as alternative rock and grunge. His influence on the latter caused some to dub him the "Godfather of Grunge".
