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
by 1860, about 265,000 free blacks in S states
the fight for freedom 1699-1865

Black ppl used by both armies
1862-63, black abolitionist Fredrick Douglass helped persuade President Lincoln to emancipate slaves + allowed blacks to join Union army
black soldiers joined 54th + 55th Massachusetts Volunteers at New Bedford
18 July 1963 54th, commanded by Colonel Robert Gould Shaw, brave charge on Fort Wagner in Charleston Harbour
