Scientific Explanation

🗝 history 📚

introduction

great civilisations

Ghana 8-12th century

Mali 12-15th century

Songhay c. 1500

Benin

Muslim empires in North Africa

Islam spread south 11-16th century

16th and 17th c, Europeans thought Africans inferior and uncivilised, so felt justified enslaving them

Muslim traders - dangerous journey south across Sahara - luxury goods, salt, firearms to exchange for gold, leatherwork

W Europe 📉, great African civilisations 📈

Africa flourished bc gold + salt

great cities like Timbuktu, centres of learning + 🎨

1. black cargoes

16th century white Europeans began taking big no. black Africans to the Americas as slaves

idea of slavery is old

Spanish colonisation of Americas in 16th needed physical labour (clear woodland, cultivate crops, mining)

Americas called New World

Spanish forced native ppl of Americas (e.g. Incas and Caribs) to work under harsh conditions #

exposed to new + fatal diseases from Europeans, native ppl died in millions so

by early 16th century, Spanish needed alternate labour source

Asiento - import licence carrying privilege of controlling slave traffic to Spanish dominion in New World

15th century Portuguese built trading stations in Africa - by end of century, importing 10,000 African slaves into Lisbon/year - also Spanish #

mostly went to Portuguese sugar plantations

some in Madeira

first as house servants and farm labourers then

from beg. 16th century, next three centuries, slaves used on sugar plantations in Caribbean, Brazil, Mexico, massive expansion as Portugese + Spanish established control of New World

Most slaves sold by African slave dealers

often enslaved for debt, punishment for crime, prisoners of wars/fighting

Europeans traded guns for slaves

The Triangular Trade

Sir John Hawkins began English involvement in slave trade

began triangular trade in 1562

Other countries followed his example - France, Netherlands

English did not have Asiento, but Hawkins made 3 more trips 1562-68
Encouraged by Queen Elizabeth - profitable to English

appalling death and hardship - millions captured Africans

slaves kept in forts along coast of W Africa European captains went ashore + did business w/ African chiefs/traders then herded human 'cargo' onto overcrowded ships

then Middle Passage across Atlantic Ocean - high death rate

1680-88, British Royal African Company lost almost 1/4 of all slaves

shackled w/ leg-irons, branded w/ red-hot iron, heads shaved, clothes taken away

Plantation Slavery in North America

First Africans in NA early during colonisation - 1619

developed slowly -increasing as growth of tobacco trade in 17th century created worker demand

by mid 18th cent, > 260,00 African slaves in Virginia (mostly transported, not born)

then 📉 as tobacco trade reduced

📈 as cotton as crop, especially after invention of cotton gin - 1793 - Eli Whitney (American from Conneticut)

engine that speeded up process of separating cotton fibre from seeds

more cotton could be separated/day, more cotton needed collection, more slaves needed

supply rapidly expanding textile industry in Britain

Slaves who survived Atlantic crossing reached NA, sold at large ports + towns

put to work on cotton, tobacco, sugar beet, 🌾 (rice) plantations in S states 17-18th cent

💰 of plantation owners depended on this

plantation slavery called 'The Peculiar Institution of the South' one of most cruel human systems

1526-1870, approx. 10 million Africans 🚢 to Americas - some say estimate too ⬇ does not account for all those who died

2. to be sold as a slave

urbanisation

Landscape

Environmental

Economic

Social

shopping

jobs

tourists

isolation

crowded

crime

roads

skyscrapers

greenery

pollution

animals

why do things cost more in urban areas?

why do tourists visit urban areas?

why can you find more jobs in urban areas?

why are crime rates higher in urban areas?

what are the pros and cons of crowded areas?

why are there more feelings of isolation in urban areas?

why are buildings so tall in urban areas?

why are there more roads in urban areas than in the same amount of space of a rural area?

how much greenery is there is urban areas and why?

how are urban areas so much more polluted than rural areas?

why aren't there as many animals in urban areas?

slaves sold in different ways

the 'scramble'

1 method of selling - horrifying to newly arrived slaves

herded together - sometimes sold at fixed price per head - purchasers rushed + grabbed ones they wanted to buy

auctions

many slaves held in slave pens until sold

commonly public auction

sometimes paraded + examined like animals

slave stood on auction block while bidding took place

often by inch of 🕯 - bids received until inch of 🕯 burned

sometimes families kept together - usually separated

branded + sold like cattle

prices varies greatly - young, old, well, ill, skilled, unskilled

unhealthy slaves who could not be sold often left to die on wharfs

slaves given European names to try + make them forget African past

branded - w/ owners initials or a mark

3. a life of slavery

sugar-cane grown in West Indies

Cotton, tobacco, rice in NA

coffee ☕ + sugar in central + SA

West Indies

strongest adults cleared land, planted and dug, cut ripe canes, worked in mill-house

bigger children, old, and weaker slaves did weeding

young children tended garden + collected animal feed

North America

water-toters

5-6 yrs - water toters

10 yrs - general work - quarter hands

then half hands

when 18, full hands

grew old, started down scale + ended as quarter hands

quarter hands

half hands

three-quarter hands

full hands

hard work, regular punishment, poor diet, lack of medical care meant many slaves died young

Living conditions

👕 👖 of coarsest wool/cotton - called 'homespun'

children 👟less even in winter

monotonous food - cornmeal/ 🍠 varied by food from slaves' veg plots if allowed

housing usually 1 overcrowded room

if 🍖 available, poor quality

slave quarters usually in rows behind big ◻ 🏡 for owner

perfect for disease

  • overcrowded
  • poor sanitation

punishment

1660s, slave codes in British colonies of NA

stated meals, punishments, clothing, etc.

but were ignored w/out difficulty - slaves had no rights

commonly whip

punished by white overseer or black driver

15-20 lashes

rawhide - cut into skin, leather strap - stung skin w/out cutting it

some employed 'slave breakers' to force new/young slaves to submit to system

fetters/shackles - control + punish runaways

some runaways escaped even with collars/fetters

locked in plantation jails/medieval-style stocks

not all slaves lived on plantations - skilled slaves hired by companies to work

e.g. sawmills, gristmills, 💎 mines, 🐟 fisheries

deck hands, 🎣 fishermen

build 🛣 roads, canals, 🌉 bridges, 🛤 railroads

by 1860, probably 1/2 million slaves worked in S USA - virtually every skilled/unskilled occupation

in towns, made to wear numbered copper tags for identification

also servants in town houses - cooks, housekeepers, gardeners

also in hotels

cotton presses, tanneries, shipyards, bakehouses, etc.

free blacks

sometimes bought their own freedom

could hire themselves out

gave half to owners

saved half

price of freedom decided by owners, called manumission
