TRAUMA-INFORMED LESSON. Transatlantic slave trade was 400-year system 1441-1888 that forcibly transported ~12.5 million Africans + cost ~1.8 million lives in Middle Passage alone + reshaped Africa + Americas + Europe + global economy. Today centers AFRICAN VOICES per Teaching Hard History K-12 + 1619 Project K-12. PRE-1441 — Saharan trans-Saharan slave trade existed prior (~7M Africans enslaved across Sahara 700-1900 per Lovejoy 2012). PORTUGUESE ATLANTIC SLAVE TRADE BEGINS — Antão Gonçalves 1441 first African captives to Lagos Portugal; 1444 first systematic raid (Gomes Pires + Lançarote de Freitas — 235 captives); 1482 ELMINA CASTLE built Gold Coast (modern Ghana, 100 km west Accra) — São Jorge da Mina, World Heritage Site; first European-built structure in sub-Saharan Africa. KONGO KINGDOM — Manikongo Nzinga a Nkuwu baptized 1491, Afonso I r.1509-1542 devoted Catholic + Portuguese-educated — yet Portuguese enslaved Kongo subjects despite Kongo's diplomatic protests (Afonso's 1526 letters to King João III). AFRICAN POLITICAL ACTORS — Asante (founded ~1670 Osei Tutu, Akan-speaking, gold-rich) + Dahomey (Fon-speaking, 1700s) + Oyo (Yoruba-speaking, 1600-1800s) + Benin (Edo-speaking, Benin Bronzes 13th-19th c.) participated as African polities in trade (refusing both 'Europeans acted alone' AND 'Africans sold Africans' simplistic framings per Thornton 1998 + Heywood 2007). DEMOGRAPHICS per SlaveVoyages.org (Eltis et al. 2009): 12.5 million Africans EMBARKED + 10.7 million ARRIVED + 1.8 million died Middle Passage; African region origin — West Central Africa (Kongo/Angola) ~40% + Bight of Benin ~16% + Bight of Biafra ~14% + Gold Coast ~10% + Senegambia ~6% + Sierra Leone ~5% + Windward Coast ~3% + Mozambique ~5%; national carriers — Portuguese ~5.8M + British ~3.1M + French ~1.4M + Spanish ~1.1M + Dutch ~0.5M. AFRICAN VOICES — OLAUDAH EQUIANO (Gustavus Vassa) c.1745-1797, Igbo-born, kidnapped age 11 + Middle Passage to Barbados + Virginia + bought freedom 1766 + abolitionist; 1789 Interesting Narrative — primary source. AYUBA SULEIMAN DIALLO (Job ben Solomon) c.1701-1773, Senegambian Fulbe Muslim scholar from Bondu, kidnapped 1730 + enslaved Maryland + freed 1734 + returned to Senegal. PHILLIS WHEATLEY 1753-1784, Senegambia-born, enslaved Boston, first published African American poet 1773. AYUBA SULEIMAN DIALLO refutes 'cultureless captive' framing absolutely — Muslim scholar fluent in Arabic.

Key examples
  • Apply Teaching Hard History style — 'enslaved people' not 'slaves'; refuse 'sad chapter' euphemism. Equiano's voice centered. MG-15 trauma-informed protocol active.
    model Equiano (Chapter 2) describes sensory experience of slave ship hold — 'a salutation of my nose with such loathsomeness as I had never experienced... the closeness of the place... the heat of the climate, added to the number in the ship... the shrieks of the women, and the groans of the dying.' First-person account shows experiential reality that 1.8M Middle Passage deaths statistics cannot convey. Equiano was 11 when kidnapped + survived + bought freedom + became leading abolitionist + sold ~10,000 copies of his Narrative in lifetime.
    prompt Read one paragraph from Equiano's 1789 Narrative on Middle Passage. What does his account show that statistics cannot?
  • Apply this language discipline consistently.
    model Teaching Hard History (Learning for Justice 2018/2022) style guide: 'slave' is noun defining person by condition of enslavement; 'enslaved person' centers the person + names enslavement as something DONE TO them by enslavers. Refuses naturalizing the condition. Teaching Hard History 6-8 Key Concepts also: (1) refuse 'sad chapter' euphemism; (2) center African voices; (3) name African political actors without simplistic 'Africans sold Africans'; (4) connect to ongoing racial injustice (1619 Project framing).
    prompt Why teach 'enslaved people' not 'slaves' per Teaching Hard History style guide?
Checks for understanding
  • When did the Atlantic slave trade begin? Where?
  • Name 2 African voices that survive as primary sources.
  • Why 'enslaved people' not 'slaves'?
