Buy low in Canton. Sell high in Leadenhall Street. Learn what the ledgers hid.

Hist_EastIndiaCompany.js is a trade sim and history module in one plugin. Your merchant NPC, harbour master or history classroom gets a full turn-based voyage game — and the exhibit tells the rest of the story.

⚓ Company Ledger (trade sim)

Seven ports — London, Cape Town, Surat, Bombay, Madras, Calcutta, Canton. Nine cargoes — tea, silk, porcelain, calico, pepper, saltpetre, indigo, provisions and the silver that bought the tea. Sail with the monsoon (south-west from April, north-east from October) or lose a month and risk a storm. Keep provisions aboard or scurvy takes the crew. Reach your profit target before the charter’s months run out, then settle at East India House for a voyage summary.

• The calendar matters. When your voyage crosses 1757 (Plassey), 1765 (the Diwani), 1770 (famine), 1773 (Tea Act), 1793, 1799 or 1813, the event is logged and the markets move.
• A Chart overlay draws the route graph with months per leg and a monsoon rose.
• Port cards and cargo notes teach as you trade; the silver mechanic shows why the opium trade happened.
• Opium is not a tradeable good and cannot be enabled. It, the famine, 1857 and Crown rule are taught in the exhibit, not played.

⛵ Monsoon Navigator (arcade)

Hold OK to raise sail. Green gusts push you across the Bay of Bengal, red ones push back, and when the SQUALL AHEAD warning flashes you reef or take hull damage. Supplies tick down every day.

📚 Ledger of Consequences (exhibit)

Twenty-one dated entries from the 1600 charter to the 1874 dissolution, plus eight topic cards: opium & the silver drain, sepoys, nabobs, indigo, lascars, tea & Boston, weavers & calico, the Dutch VOC.

🎓 Company Examination

Fourteen true/false questions in the style of the Company’s Haileybury college, each explained, with streak bonuses.
