In 1724 Johann Sebastian Bach composed the church cantata Meine Seel erhebt den Herren, BWV 10, as part of his second cantata cycle.  Taken from Martin Luther's German translation of the Magnificat canticle ("Meine Seele erhebt den Herren"), the title translates as "My soul magnifies the Lord".  Also known as Bach's "German Magnificat", the work follows his chorale cantata format. "Den Pobedy" (Russian: День Победы , English: Victory Day ) ranks among the most popular in the large corpus of Russian songs, devoting to Second World War.  The song refers to the Victory Day (9 May) celebration and differs from most of these by its cheerful intonations of a marching song and by the fact that it was composed some thirty years after the war.  In the words of Vladimir Shainsky, a veteran composer, "the song seemed to have turned back the time.  Although written three decades after the war, it now seems that it was this song that helped us to gain the victory". The Hendrik J. and Wilhelmina H. Van Den Berg Cottage is an historic building located in Pella, Iowa, United States.  During the 1840s and the 1850s immigrants moved to Iowa from the Netherlands to escape religious persecution.

It exemplifies the first generation of houses built in Pella and exhibits architectural influences of the Netherlands.  It is one of only a few such structures that still remain in the town.  The house was listed on the National Register of Historic Places in 2003.

An asylum seeker (also rarely called an asylee) is a person who flees his or her home country, 'spontaneously' enters another country and applies for asylum, i.e. the right to international protection, in this other country.  An asylum seeker may be a refugee, a displaced person or a migrant, such as an economic migrant.  A person becomes an asylum seeker by making a formal application for the right to remain in another country and keeps that status until the application has been concluded.  The relevant immigration authorities of the country of asylum determine whether the asylum seeker will be granted protection and becomes an officially recognised refugee or whether asylum is refused and the person becomes an illegal immigrant who has to leave the country again and may even be deported.  The asylum seeker may be recognised as a refugee and given refugee status if the person's circumstances fall into the definition of "refugee" according to the Vladimir Yakovlevich Shainsky (Russian: Владимир Яковлевич Шаинский ; born 12 December 1925) is a Soviet and Russian composer.

Aus den Bergen ("From the Mountains"), opus 292, is the name of a waltz composed by Johann Strauss II.  The work was first performed in Pavlovsk on October 2nd 1864, under the title "In den Bergen".  The composition was dedicated to the music critic Eduard Hanslick.  Critics commented on Strauss' waltz that "after a long time a new waltz from Johann Strauss has appeared, which is distinguished by noble and graceful character, and further distinguished by extraordinarily masterful instrumentation."  The first Viennese performance of the waltz was in the Volksgarten as part of a benefit concert commemorating Strauss' twentieth anniversary of his debut as a composer.
