La Marcha de los Entrelazados ("the March of the Intertwined" in Impelanzan), also known as Marcha de la Liberación (March of Liberation) is, since December 23rd 1920, the official anthem of The Cooperative Commonwealth of New Leganés, Oblivion Islands and Shoneria. It was originally conceived as a poem by the popular Shonerian poet Federico del Arco, who was involved in the 1920 Cukish Revolution, and it soon caught the attention of the composer Perelio, who managed to create a musical arrangement for the poem and gave it the name of Marcha de los Entrelazados.
After that, it started to spread among the democratic revolts and it ended being the de facto anthem of the revolutionaries. Federico del Arco and Perelio were considered "public enemies" by the deputation of Shoneria and, later, by the Commonwealth Government and were arrested. The trial was made public in the now called Freedom Square, Privetia Taurillien, but it didn't take place as the revolutionary crowd invaded the square, singing the Marcha, and killed the whole jury. Its popularity reached all the Commonwealth and it was played in almost every revolt, until the war ended and the revolution succeeded.
It was then included in the new constitution as the official national anthem and it was played in the Senate by the singer Nádina Falemádi and an orchestra made of flutes, ocarinas and bagpipes after the new Commonwealth Government signed the constitutional text, in presence of both Federico del Arco and Perelio.
