islandsNgazidja

Ngazidja, also known as Grande Comore, is the largest island of the Comoros archipelago in the Indian Ocean. It lies off the eastern coast of Africa, near Madagascar and Mozambique, and forms the central core of the Union of the Comoros. The island is of volcanic origin and features a rugged interior with Mount Karthala, one of Africa's largest active volcanoes, which has erupted repeatedly in recent decades. The coastal zone is more densely populated and hosts Moroni, the national capital, located on the eastern coast.

Administratively, Ngazidja forms the Ngazidja Province within the Union of the Comoros. The population is concentrated along the coast, and Ngazidja is the most populous island in the archipelago.

Economy relies on agriculture, including vanilla, cloves, ylang-ylang, and coconuts, as well as fishing and small-scale commerce. Tourism exists but remains limited, with interest in volcanic landscapes and beaches.

Ethnic groups include Comorian communities, and the main religion is Islam. Shikomor (Comorian) is widely spoken, with French and Arabic used in administration and education. The island has a history of sultanates before becoming part of the French Comoros, attaining independence in 1975 along with the other islands.

Transportation features include the international airport near Moroni, Prince Said Ibrahim International Airport (Hahaya), and a port at Moroni.
