Nagari Sakti (Sacred land) is the national anthem of Kertosono. It has been the national anthem since Kertic unification in 1901. The song was chosen in a contest held to select the new nation's anthem, and was presented by KRT Sosrodiharjo Kromodibroto on the 18th of July 1901. The song marked the birth of pan-Kertic identity and sense of belonging, and is seen as a firm solidifier of a single state for the Kertic peoples, rather than be split into a large number of smaller states, often competing with one another instead of cooperating. The anthem was first published in Warta Kawula on the 3rd of October 1901, announcing the winner of the contest.
The anthem is notoriously challenging to sing, owing to its very wide vocal range, complex and winding melody, and its dated vocabulary. Its heavy use of literary and archaic terms renders the anthem unintelligible for most common people unaware of the literary Kertic language, and is a source of dispute and argument in Kertosono.
Devoting oneself towards the miraculous state with a long life building and constructing In the middle of our place of strife Kertosono the heroic towards the exalted and examplified God May you be safe and be hindered from any troubles Kertosono the beloved in our hearts In noble times the soliders of the eternal battlefield Always tedious in real work at the sunrise of the smiling sun as it shines bright The love story of the role-model warrior The state-devotees are fighting with their mgiht towards the nation while the native land greets happily At haste, become a warrior for your country ready to bear the duties of Kertosono A noble, rich, and well-laden country, the palace of will at His helm The splendid times guides the wanderer towards the imperial gates of heaven The two forms of love of God towards all of his creations Await us, your fighters, always devoting themselves towards the miraculous state and country of Kertosono Always faithful in devotion with full love and may happiness descend on all the peoples A symbol of miraculous divotion towards the country, and devoting to god through Kertosono!
