How does standard sources define trade?
Voluntary exchange of goods and services — mutually beneficial to both buyer and seller; requires two parties.
Two levels of trade?
International (across national boundaries) and National (within a country).
What was the earliest form of trade?
Barter system — direct exchange of goods.
Where in India does BARTER trade still survive as a community practice?
JON BEEL MELA at Jagiroad (~35 km from Guwahati, ASSAM) is held every January after the harvest — alongside the confluence where the Tiwa + nearby tribal communities have traded for centuries. Mela-goers literally swap rice for fish, vegetables for forest produce, oil for cloth — without money changing hands. The fair survives partly as a cultural ritual + partly because of the genuine economic logic of barter among small communities. Anthropologists + geographers cite it as among the LAST surviving organised barter exchanges in India.
What overcame the difficulties of barter?
Introduction of money — initially rare objects with high intrinsic value (flintstones, obsidian, cowrie shells, tiger paws, whale teeth, salt, copper, silver, gold) before paper + coin currency.
Why does the word SALARY trace etymologically to SALT?
In Latin, SALARIUM meant "salt money" — derived from SAL (salt). Ancient Roman soldiers were paid an allowance specifically for purchasing SALT — at a time when salt was expensive + difficult to produce (only obtainable by mining rare rock salt or laboriously evaporating sea water). Because salt was a recognised store of value + a portable medium of exchange, it served as one of the earliest forms of WAGE — + the word followed the function. The same root produces "saline", "salad" (originally salted vegetables), + the English idiom "worth one's salt".
Why was ancient long-distance trade restricted to luxuries?
Transport was risky; people spent most resources on basic necessities; only the rich bought jewellery + costly dresses.
What was the SILK ROUTE + why is it historically significant?
The SILK ROUTE was a roughly 6,000 km overland TRADE NETWORK that linked CHINA in the east to the ROMAN EMPIRE in the west — flourishing between ~200 BCE + ~1400 CE. Far from a single road, it was a web of branching caravan tracks across CENTRAL ASIA, PERSIA + the Indian subcontinent. CHINESE SILK + porcelain + tea flowed west; ROMAN GOLD + WOOL + glass flowed east; INDIAN cotton + spices + pepper + precious stones joined at intermediate hubs (Taxila, Bactria, Samarkand, Bukhara). The Route also moved RELIGIONS (Buddhism into China; Islam into Central Asia), TECHNOLOGIES (paper, gunpowder), + diseases (plague, smallpox). It is the earliest example of large-scale Eurasian commercial integration.
What expanded European trade in the 12th-13th centuries?
Disintegration of Roman Empire; rise of ocean-going warships; trade between Europe and Asia grew; Americas were discovered.
What HORRIFIC NEW FORM of trade emerged from the 15th century onward?
European COLONIAL expansion from the 15th century onwards opened a new + brutal commercial geography: the TRANS-ATLANTIC SLAVE TRADE. Portuguese, then Dutch, Spanish, British, French + Danish traders captured Africans (mostly from West + Central Africa) + shipped them in horrific conditions across the Atlantic to the AMERICAS — where they were enslaved + forced to work on sugar, cotton, tobacco + coffee plantations supplying European markets. Estimates: 12-15 MILLION Africans were transported between 1500-1888; ~2 million died en route. The slave trade transformed African societies, built European wealth, + created the demographic + economic foundations of Brazil + the Caribbean + the southern United States.
When was slave trade abolished?
Denmark 1792, Great Britain 1807, United States 1808.
How did the Industrial Revolution change trade dynamics?
Demand for raw materials (grains, meat, wool) expanded; monetary value of raw materials declined relative to manufactured goods. Industrialised nations imported primary products + exported finished goods to non-industrialised nations.
