            "description": " The following quotes suggests use of cattle as currency from before the 19th century. \"By the 19th century, both Milansi and Karagwe kingdoms were major players in a lucrative trade that involved the coast and the interior. [...] Before we move along to specific cases, it is imperative to note that before these kingdoms got into long-distance trade they must have started with short-distance trade which often appears naturally as a result of unequal distribution of natural resources and specialization. For example, not everyone in the community kept cattle though it played a central role in dowry payment. Thus, a farmer would barter cereals for cattle when a need for the latter arose and vice versa.\"§REF§(Mapunda 2009: 99) Seshat URL: https://www.zotero.org/groups/1051264/seshat_databank/collections/GWWIKDDM/items/9GV5C5NF/collection. §REF§ \"In the southern Sudan and some parts of East Africa - for example, in Karagwe - ivory was valued in terms of cattle, and this was one of the causes of the cattle raids carried out by ivory dealers.

Pastoralists bartered their surplus of animals and animal products (milk, clarified butter, wool, hides, skins, etc.) for the goods of agricultural communities (grain, oil, clothing, wine, arms, etc.).\"§REF§(Hoyland 2001, 110) Hoyland, R. 2001.
