Chapter 21 – Africa in an
Era of Slave Trade
Trans-Atlantic Slave Trade
This is a chapter on
processes and impacts
What institutions were involved in the
slave trade and in what order?
 How did technological developments
contribute to the slave trade?
 What was the social impact of the slave
trade in the Americas? In West Africa?
 What role did Africa have in the
Columbian Exchange?

Stages





Portuguese established trading forts
(factories); ie El Mina – gold from interior
Most forts established with permission from
African kings who desired trade.
Portuguese and African traders
(landcados) followed routes to the interior
to open new markets.
Missionary efforts followed – really only
Benin and Kongo had any early success.
King Nzinga Mvemba for trade relationship
In the 1570’s Luanda and Angola were
established among the Mbundu.
 In the Indian Ocean they established bases
on Mozambique island to control gold trade
from Monomotapa.
 Other Europeans followed Portuguese
patterns and in almost all instances slavery
eventually became the principal focus of
relationships.

Organization of Trade
Before 1630 the Portuguese were the
original suppliers.
 The Dutch then took over el Mina and
became suppliers.
 By 1660, the English were supplying
their own colonies.
 The French followed in the 1700’s.
 Each nation established forts for
receiving slaves.

The value of a man (Indies Piece) was
calculated in currencies such as iron
bars, brass rings and cowry shells.
 Dahomey had a royal monopoly on
slave flow.

The Slave Trade
1. Existed in Africa before the coming
of the Europeans.
2. Portuguese replaced European slaves
with Africans.
Sugar cane & sugar plantations.
First boatload of African slaves
brought by the Spanish in 1518.
275,000 enslaved Africans exported
to other countries.
3. Between 1450-1850, about 12 million
Africans shipped to the Americas.

Trend Toward Expansion





Out of those slaves exported, only 10 or 11
million arrived alive.
A number equal to 1/3 of that number is
believed to have perished in initial raids to
collect and the march from the interior to
the African coast.
80% of the slaves that came, came in the
1700s = 18th century.
Brazil received 40% of the slaves coming
to the Americas.
At the same time, there were still African
slaves being traded by the Muslims around
3 million.
Demographic Patterns





The Muslim slave trade carried mostly
women for sexual and domestic
employment.
The Atlantic trade forcused on young men
fit for hard labor.
African societies who sold slaves might
keep women and children for their own
uses.
West African population is believed to have
been half of what it would have been
without the trade.
Maize and Manioc helped suffering regions
to recover from population losses.

crops, Columbian Exchange
and the social impact of the
Atlantic Slave Trade.

Question of Profitability
First of all, the profits of the slave trade
have been linked to the rise of
commercial capitalism and the Industrial
Revolution.
 Individual voyages did bring profits to
merchants and ports involved, but…

 There were risks in the business such as
loss of life by mutiny or loss of valuable
property as a potential slave. Infections from
dying slaves on the ships. Etc.
English profitability in the late 1700’s
was about 5 to 10% profit which is equal
to other commercial ventures, but with
more risk.
 Of course the labor it supplied was
essential to the mining and agricultural
economies that built American
capitalism.
 The triangle trade incorporated Africa
into the world economy.

5. New Patterns of World Trade
African Societies
Individuals who could somehow get
themselves a slave could gain wealth
and status for themselves and their
lineage.
 Slaves were treated differently
depending on the local system

 Kinship systems were normally less severe
 Under centralized hierarchical societies,
slaves were economically and socially
exploited.
Slaving and African Politics
Most of the states of west and central
Africa were small and unstable.
 The continuing wars elevated the
importance of the military and promoted
the slave trade.
 Increasing centralization and hierarchy
developed in the enslaving societies

Those attacked reacted by augmenting selfsufficiency and antiauthoritarian ideas.
 A result of the presence of the Europeans
along the western coast was a shift of the
locus of African power.
 Inland states close to the coast, and
therefore free from direct European
influence, through access to Western
firearms and other goods, became
intermediaries in the trade and expanded
their influence.

Asante
The Asante were between the Hausa
and the coast.
 They gained access to firearms in 1650
and began centralizing and expanding
 Osei Tutu became asantehene –
supreme civil and military leader
 By 1700, they were doing business
directly with the Dutch.
 Maintained power until the 1820’s

Fall of Benin, Rise of Dahomey
Benin was at the height of its power when
European arrived.
 The ruler controlled the trade with
Europeans and slaves were never a
primary commodity.
 Dahomey, however, emerged in the
seventeenth century and by the 1720’s had
access to firearms leading to the formation
of an autocratic regime based on trading
slaves.
 The states maintained its policies into the
nineteenth century.

New Form of Religion

Vodun in the Caribbean
Overall Effects
Too much emphasis on the slave trade
obscures creative processes occurring
in many African states.
 Growing divine authority of rulers
paralleled the rise of absolutism in
Europe.
 New political forms emerged that limited
the power of some monarchs.

In the Yoruba state of Oyo, a council and
king shared authority
 Art, crafts, weaving, and woodcarving
flourished in many regions.
 Benin and Yoruba states created
remarkable wood and ivory sculptures.

East African Slaves





Swahili trade towns had been active since
the Muslim trade began; that continued.
The commerce that went out of those ports
included ivory, gold and slaves.
Those items usually went to Middle
Eastern markets.
A few slaves went to European colonies.
On Zanzibar and other islands, Arabs ,
Indians, and Swahili produced cloves with
slave labor.
Inland East Africa
Migrants from the Upper Nile valley
moved into Uganda and Kenya where
they mixed with Bantu-speaking
inhabitants.
 Strong monarchies developed in
Bunyoro and Buganda.

Sudan
The process of Islamization entered a new
phase linking it to the external slave trade.
 In the 16th Century Songhay broke into

 Bambara of Segu – pagan
 Hausa states of northern Nigeria –
Muslim/animistic
1770’s Sudan underwent Muslim reforms
New Muslim reforms in West African
interior accelerated cultural and social
change by the 1840’s
 Local slave labor also increased in
agricultural and manufacturing enterprises.
