"Ja, vi elsker dette landet" - 'Yes, We Love This Country') is the national anthem of Norway. Originally a patriotic song, it became commonly regarded as the de facto national anthem of Norway in the early 20th century after being used alongside "Sønner av Norge" since the 1860s. It was officially adopted in 2019.

The lyrics were written by Bjørnstjerne Bjørnson between 1859 and 1868, and the melody was written by his cousin Rikard Nordraak sometime during the winter of 1863 to 1864. It was first performed publicly on 17 May 1864 in connection with the 50th anniversary of the constitution. Usually, only the first and the last two verses are sung, with the first being by far the most common.

"Poland Is Not Yet Lost", also known as the "Dąbrowski Mazurka", and the "Song of the Polish Legions in Italy", is the national anthem of Poland.

The Star-Spangled Banner is the national anthem of the United States. To celebrate their victory over British forces during the War of 1812, U.S. soldiers raised a large American flag at Fort McHenry in Baltimore, Maryland, on September 14, 1814.
