Mursi tribe inhibits an inaccessible area between the rivers Mago and Omo. It's language belongs to the Nilo-Saharian languages. The population of this tribe is estimated at 10.000. It is divided into 18 clans. The most valuable treasure of every Mursi is cattle. Even the names are given according to the color of your favorite cow. Mursi people boast among local tribes with the largest number of cattle, therefore they are considered to be the richest. All social relationships are approved by the exchange of cattle. The dowry is usually constituted by 30-40 cows, although today it is more often also a rifle. This wealth goes from a groom's family to a bride's family. Therefore, the birth of a girl is treated as a blessing - it contributes to the growth of a father's wealth. This does not mean that male descendants are less important; they will look after the flocks.
