What this dot point is asking
This dot point covers the Middle Passage, the Atlantic crossing on which enslaved African people were carried from West Africa to the Americas. The SQA British context requires you to know what conditions were like on board: the tight packing, the overcrowding, the disease, the cruelty, the lack of food and water, and the high death rate. You also need to understand why slave traders packed ships so densely. This is one of the most heavily examined parts of the topic, both as a Describe question on conditions and as an Explain question on why so many died.
The dot point matters because the Middle Passage came to symbolise the cruelty of the whole trade, and accounts of it were central to the abolition campaign. It also requires sensitivity and accuracy: the answer should describe the conditions plainly and factually. Questions are usually Describe (conditions) or Explain (why so many died).
The answer
The Middle Passage was the brutal sea voyage from West Africa to the Americas, which could last several weeks. Enslaved people were packed tightly below deck with little room to move, men often chained together in pairs, so traders could carry as many captives as possible. The hold was hot, airless and without proper sanitation, so it became filthy. Disease, especially dysentery and smallpox, spread rapidly through the crowded space, and food and clean water were limited and poor, weakening those on board. Some captives died of disease, some from cruelty or being thrown overboard, and some from despair. The death rate was very high. Conditions were so terrible that the Middle Passage became one of the strongest arguments used by those campaigning to abolish the trade.
Overcrowding and tight packing
Slave traders packed their ships as tightly as possible because the more captives they carried, the greater the profit. Enslaved people were forced into low decks with so little headroom that they could not stand, and men were frequently chained together in pairs to prevent rebellion. This extreme overcrowding meant people lay pressed together for weeks, which made the spread of disease almost inevitable.
Disease, food and sanitation
The crowded hold had little fresh air and no proper sanitation, so conditions quickly became filthy and the air foul. Diseases such as dysentery, smallpox and fevers spread rapidly through the packed space. Food and clean water were limited and of poor quality, so captives grew weak and more vulnerable to illness. The combination of overcrowding, filth, poor food and disease made the hold deadly.
Cruelty, despair and death
The voyage was marked by cruelty. Captives who resisted or who fell ill might be beaten, and the sick and dying were sometimes thrown overboard. To keep captives saleable, traders sometimes forced them on deck to exercise, or "dance", under threat of the whip. The conditions and the hopelessness drove some to refuse food or to take their own lives. Between disease, cruelty and despair, a high proportion of those who set out did not survive the crossing.
Examples in context
A Describe question asks for the conditions, so state them as facts: captives were packed tightly below deck unable to stand; men were chained in pairs; the hold was hot, airless and filthy; disease such as dysentery and smallpox spread quickly; food and water were poor; the sick were sometimes thrown overboard; captives were forced to exercise to stay saleable; and many died on a crossing that took weeks.
An Explain question on why so many died links causes to effects: "ships were packed tightly for profit, so overcrowding spread disease fast"; "the hold was airless and filthy, which let illness thrive"; "food and water were poor, so people weakened"; "diseases spread through the crowd, which killed many"; "cruelty and despair added to the toll".
Try this
Q1. Why did slave traders pack their ships so tightly? [2 marks]
- What the marker wants. To carry as many captives as possible and so maximise profit, which caused the extreme overcrowding of the Middle Passage.
Q2. Name two diseases that spread on the Middle Passage. [1 mark]
- What the marker wants. Any two of: dysentery (the "bloody flux"), smallpox, fevers.
Q3. Give two reasons, besides disease, that enslaved people died on the crossing. [2 marks]
- What the marker wants. Any two of: cruelty and beatings; being thrown overboard when sick or dying; despair leading some to refuse food or take their own lives.

A Describe question, so make six separate, developed points of fact from recall.
Possible points: enslaved people were packed tightly below deck with little room to move; men were often chained together in pairs; there was little fresh air, and the heat and lack of sanitation made conditions filthy; disease such as dysentery and smallpox spread quickly in the crowded hold; food and clean water were limited and poor; the sick and dying were sometimes thrown overboard; some were brought on deck and forced to exercise, or "dance", to keep them saleable; and many died on the crossing, which could take weeks.
Any six accurate, developed points reach full marks. Keep each one factual.
SQA N5 style6 marksExplain the reasons why so many enslaved people died on the Middle Passage. (6 marks)Show worked answer →
An Explain question, so give developed reasons linking cause to effect, around six.
Developed reasons: ships were packed tightly to carry as many captives as possible, so overcrowding spread disease rapidly; the hold had little fresh air and no proper sanitation, which meant filthy conditions in which illness thrived; food and clean water were limited and poor, so people grew weak and ill; diseases such as dysentery and smallpox spread through the crowded hold, which killed many; some died from cruelty, beatings or being thrown overboard, so violence added to the toll; and despair drove some to refuse food or take their own lives, which raised the death rate further.
Each reason must carry the factor through to its consequence.
