Igboland (Standard ), also known as Southeastern Nigeria, is the indigenous homeland of the Igbo people. It is a non-governmental cultural and common linguistic region in southern Nigeria. Geographically, it is divided by the lower Niger River into two unequal sections – an eastern (which is the larger of the two) and a western section. It is characterised by the diverse Igbo culture and the equally diverse Igbo language.
Politically, Igboland is divided into several southern Nigerian states. Culturally, it is divided into several subgroupings, including the Anioma, Ngwa, Edda Egbebu, Ezaa, Ibeku, Ohuhu, Omuma and the Ekpeye. William Balfour Baikie remarked that "in Igbo[land] each person hails, as a sailor would say, from the particular district where he was born, but when away from home all are Igbos. And yet considerable differences exist between different parts of this extensive country, and the dialects spoken also vary greatly."
