"Udzima wa ya Masiwa" (Comorian for "The Union of the Great Islands") is the national anthem of Comoros. Adopted upon independence in 1978, it was written by Said Hachim Sidi Abderemane who also composed the music, along with Kamildine Abdallah.
Mayotte (claimed by the Comoros, but under French administration) is also mentioned in the song.
