Tivland (Nigeria)

"Tiv are an ethno-linguistic group or ethnic nation in West Africa. They constitute approximately 2.5% of Nigeria's total population, and number over 5.6 million individuals throughout Nigeria and Cameroon. The Tiv's traditional language is spoken by over 6 million people in Nigeria, with a few speakers in Cameroon. Most of the language's Nigerian speakers are found in Benue State of Nigeria. The language is also widely spoken in the Nigerian States of Plateau, Taraba, Nasarawa as well as the FCT Abuja.

It is part of the Southern Bantoid Tivoid family, a branch of Benue-Congo and ultimately of the Niger-Congo phylum. The Tiv are also known as the Mitshi, Munchi, or Munshi. They depend on agricultural produce for commerce and life." (wiki)¹

James B.Minahan, in Encyclopedia of the Stateless Nations -Ethnic and National Groups Around the World - volume IV describes their flag as follows:

The Tiv national flag, the flag of the national movement, is a green field bearing twelve narrow black and white horizontal stripes across the center.

That flag appears to be incorporated into the logo of the Tiv organization in America - MUTA - Mutual Union of the Tiv in America.
