In \u201cCity Planning: Yoruba City Planning,\u201d the reading discusses the Yoruba, who are multiple groups of people such as Egba, Ondo, Awori, and Ijebu that \u201cshare a mutually intelligible language, myths of origin, religiou beliefs, cultural practices, experiences of bondage, and Anglo-France colonial heritage\u201d (1314). Historians argued that these multiple groups came together and began this \u201curbanism\u201d in Africa. The idea of multiple groups coming together, sharing and spreading ideas comes from the Mande Population Movements reading as well as the Saltwater Frontier one. In the Mande reading, it discusses the Mande speaking people as being an empire even though they did not having lasting architectural structures. Evidence shows their culture was spread in various regions. As for the Saltwater Frontier, the article discusses Native Americans and colonists sharing ideas near rivers but then become less friendly when they move away from them as mentioned by Isaias Ortiz<\/a>. Then, the reading talks about how Western scholars thought about Africa as \u201coverwhelmingly rural\u201d and tied it with \u201cthe \u2018noble savage’ imagery\u201d (1316). This wording is brought up by James Merrell who talked about how words can change a narrative, making one group more favorable than another. It makes the Yoruba seem like \u201cuncivilized\u201d people when in reality they had sophisticated cities.<\/p>\n In Jane Mangan’s \u201cPotosi,\u201d the reading talks about how the populated urban center in the colonial viceroyalty of Peru quickly became such a popular re due to large deposits of silver attracting a large population to the area. many people such as Native Andeans migrated there duin order to get money from the successful economy. It also said that \u201cthe arrival of slaves connected Potosi’s sphere of influence to Africa\u201d (2). This reading continues to show the growth of economy and society due to sharing of ideas and wealth like in City Planning: Yoruba City Planning\u201d. Again the Saltwater Frontier reading can be paralleled to this reading as well.<\/p>\n
