Alsace (French: Alsace [alzas]; Alsatian: Elsàss [ˈɛlsɑs]; German: Elsass, pre-1996: Elsaß, IPA: [ˈɛlzas]; Latin: Alsatia) is the fifth-smallest of the 27 regions of France in land area (8,280 km²), and the smallest in metropolitan France. It is also the seventh-most densely populated region in France and third most densely populated region in metropolitan France, with ca. 220 inhabitants per km² (total population in 2006: 1,815,488; 1 January 2008 estimate: 1,836,000). Alsace is located on France's eastern border and on the west bank of the upper Rhine adjacent to Germany and Switzerland. The political, economic and cultural capital as well as largest city of Alsace is Strasbourg. Because that city is the seat of dozens of international organizations and bodies, Alsace is politically one of the most important regions in the European Union.

The name "Alsace" can be traced back to the Old High German Ali-saz or Elisaz, meaning "foreign domain". An alternative explanation derives it from a Germanic Ell-sass, meaning "seated on the Ill", a river in Alsace. The region was historically part of the Holy Roman Empire. It was gradually annexed by France in the 17th century under kings Louis XIII and Louis XIV and made one of the provinces of France. Alsace is frequently mentioned in conjunction with Lorraine, because German possession of parts of these two régions (as the imperial province Alsace-Lorraine, 1871–1918) was contested in the 19th and 20th centuries, during which Alsace changed hands four times between France and Germany in 75 years.

Yusuf Islam (born Steven Demetre Georgiou, 21 July 1948), commonly known by his former stage name Cat Stevens, is an English singer-songwriter, multi-instrumentalist, educator, philanthropist, and prominent convert to Islam.

His early 1970s record albums Tea for the Tillerman and Teaser and the Firecat were both certified triple platinum in the United States by the RIAA. His 1972 album Catch Bull at Four sold half a million copies in the first two weeks of release alone and was Billboard's number-one LP for three consecutive weeks. He has also earned two ASCAP songwriting awards in consecutive years for "The First Cut Is the Deepest", which has been a hit single for four different artists.

Stevens converted to Islam in December 1977 and adopted the name Yusuf Islam the following year. In 1979, he auctioned all his guitars for charity and left his music career to devote himself to educational and philanthropic causes in the Muslim community. He has been given several awards for his work in promoting peace in the world, including the 2003 World Award, the 2004 Man for Peace Award, and the 2007 Mediterranean Prize for Peace. In 2006, he returned to pop music with his first album of new pop songs in 28 years, entitled An Other Cup. He now goes professionally by the single name Yusuf. His most recent album, Roadsinger, was released on 5 May 2009.
