"" (Comorian for "The Union of the Islands") is the national anthem of the Comoros. Adopted in 1978, it was written by Said Hachim Sidi Abderemane, who also composed the music with Kamildine Abdallah.
The spelling of the title is subject to inconsistency. In the 1978 Constitution, it was written ""; in 1992, "Udzima Wa Masiwa"; and in 2001, "". Currently, with the revisions of 2009 and 2013, it is written: "Umodja Wa Massiwa".
The anthem replaced a previous anthem titled "" ("Liberty"), also known as "" ("Four Comorian Islands"), adopted in 1976 under the Ali Soilih administration following a competition won by writer and musician Abou Chihabi. It was used until 1978, when a coup by Ahmed Abdallah and Bob Denard took place.
Mayotte, while claimed by the Comoros but under French administration, is also mentioned in the song.
