Portfolio 12

This week in digital history we explored the Voyages: TransAlantic Trade Database. This website should the showed the usefulness of tidy data. The tidy data allowed us view data from a broad perspective and then organize the data to answer a very specific question. The significance of data received is that it’s the data from the point of historical creation. Meaning the data is more than likely a primary source. This data is often not tidy, but would allow a historian to create their own derived data. The significance of derived data is that this data has come an examination of primary sources. This data is already organized, but we must use caution when using this data. We must question where the data came from and from who. The website Voyage is an example of one. Voyage has taken information from primary sources and made a research website out of it.


Interacting with voyage changed the way I ask and answer historical questions. At first using Voyage I was only asking very broad questions using the overall data. I was intrigue to learn the amount of enslaved people were imported into brazil. I will leave a questions I ask in class at the bottom of the Blog. However, when we used voyage as class I discovered I could ask much more specific questions or tell a specific story. I learn I could narrow the data down to a specific port, or the point where the enslaved where imported from such as Mozambique. Using this data I could possibly map the travel an enslaved person knowing the date the enslaved was imported and the location. I will be able to interact with contemporary data by knowing that I can use derived historical data bases to map out the data.


Research I made in class:

What made a Brazil such a huge consumer of slavery in the trans-Atlantic slave trade?

  • Tables should a huge trend upward in slave purchases in Brazil until 1850
  • US showed a similar trend but much fewer slaves. The trend also stopped in between 1826-1850. This is due to a change in us policy to the trans-Atlantic slave trade, so possibly Brazil had a similar change in policy after 1850.
  • Question remain how big of an economic impact was the this influx of slave labor had on Brazil? And how big of an impact did the policy change on trans-Atlantic slave trade affect Brazil.
  • Using the map the close proximity of South America to West Africa could make the commercial slave trade more profitable and available for Brazil.
  • Majority of voyages were about 250 days

There was a difference in the amount of slaves that embarked and the amount of slaves that disembarked

Embarked: closer to 400

Disembarked: Closer to 200 (possibly 300)

Causes of the differences?
