"italic=no|Udzima wa ya Masiwa" (also written "italic=no|Ouzima wa Massiwa",[1] Comorian for "The Union of the Great Islands"; also known as "italic=no|Umodja wa Massiwa",[2] sometimes written "italic=no|Masiwa"[3]) is the national anthem of the Comoros. Adopted in 1978,[4] it was written by Said Hachim Sidi Abderemane, who also composed the music with Kamildine Abdallah.[5]
Mayotte (claimed by the Comoros but under French administration) is also mentioned in the song.
The anthem replaced a previous anthem titled "italic=no|[[Ungwana]]" ("Liberty"), also known as "italic=no|Comor Masiwa Mane" ("Four Comorian Islands"),[6] adopted in 1976 under the Ali Soilih administration following a competition won by writer and musician Abou Chihabi.[7] It was used until 1978, when a coup by Ahmed Abdallah and Bob Denard took place.
