Grande Comore, Anjouan and Mohéli vote to become the independent nation of Comoros. Mayotte remains under French administration.

Grande Comore is an island in Comoros off the coast of Africa. It is the largest island in the Comoros nation. Most of its population is of the Comorian ethnic group. Its population as of 2006 is about 316,600. The island's capital is Moroni, which is also the national capital. The island is made up of two shield volcanoes, with Mount Karthala being the country's highest point at 2,361 m (7,746 ft) above sea level. According to the 2009 revision of the constitution of 2002, it is governed by an elected Governor, as are the other islands, with the federal government being much reduced in power. The name Ngazidja is sometimes seen in the now nonstandard form Njazidja.

Anjouan is an autonomous volcanic island in the Comoro Islands in the southwestern Indian Ocean, part of the Union of the Comoros. It is known in Shikomori as Ndzuani, Ndzuwani or Nzwani, and, until the early twentieth century when the name fell out of general use, in English as Johanna. Historically it was also called Hinzuan or Hanzoan.

Mohéli, also known as Mwali, is an autonomously-governed island that forms part of the Union of the Comoros. It is the smallest of the three major islands in the country. It is located in the Indian Ocean off the coast of Africa and it is the smallest of the four major Comoro Islands. Its capital and largest city is Fomboni.

An independence referendum was held in the Comoros on 22 December 1974. The overall result was a strong "yes" vote, with 94.57% of voters voting for independence and almost all the "no" votes being cast in Mayotte, where there was a majority for remaining under French control. In contrast, on Mohéli only five out of 6,059 votes were against independence. Voter turnout was 93.3%.
