Trade
Archaeologists have uncovered evidence of trade networks stretching 900 kilometres across the Mediterranean region as early as 12,000 BCE. These ancient routes moved obsidian from Anatolia to the Levant and Egypt. The material served as a primary component for cutting tools during the Stone Age. Communities in New Guinea exchanged obsidian as far back as 17,000 BCE. Ostrich egg shell beads traveled even further, appearing in records dating to 50,000 years ago. Robert Carr Bosanquet excavated these sites in 1901 to document the exchange patterns. Obsidian held value relative to flint because deposits were rare in many areas. This scarcity forced tribes to develop long-distance connections to access the stone. Trade existed alongside systems of credit before written history began.
The Phoenicians established trading colonies known as emporia along the coasts of the Mediterranean Sea. They sailed as far north as Britain to secure tin for bronze manufacturing. Sumerians in Mesopotamia traded with the Harappan civilization of the Indus Valley starting in the third millennium BCE. Ebla functioned as a prominent trading center reaching into Anatolia and north Mesopotamia around the third millennium BCE. Clay tokens used for accounting appeared in the Upper Euphrates valley dated to the 10th millennium BCE. These tokens represent one of the earliest surviving versions of writing. The complaint tablet to Ea-nāšir from 1750 BCE documents the struggles of a copper merchant. Roman commerce imported grain from Sicily and Egypt to feed its empire. The Pax Romana created a stable transportation network that allowed goods to move without fear of piracy.
Sogdian merchants dominated the east-west trade route known as the Silk Road from after the 4th century CE until the 8th century CE. Suyab and Talas ranked among their main centers in Central Asia. The Maritime Jade Road connected Taiwan, the Philippines, Vietnam, and Indonesia over a period spanning at least 3,000 years. Jade mined in Taiwan was processed mostly in Batanes, Luzon, and Palawan by indigenous Filipinos. This network peaked between 2000 BCE and 500 CE, predating the mainland Eurasia Silk Road. Austronesian peoples established trade routes with Southern India and Sri Lanka as early as 1500 BC. They exchanged catamarans, outrigger boats, coconuts, sandalwood, bananas, and sugarcane. Indonesians traded spices like cinnamon and cassia with East Africa using Westerlies in the Indian Ocean. This expansion reached Madagascar by the first half of the first millennium AD.
Portuguese explorer Vasco da Gama reached Calicut in 1498 after sailing around the Cape of Good Hope. He pioneered the European spice trade that had previously been controlled by Islamic powers in Egypt. Spices became some of the most valuable commodities for their weight, sometimes rivaling gold. European merchants purchased gold, spices, cloth, timber, and slaves from West African states beginning in the 16th century. The triangular trade system often exchanged these goods for cloth, iron, or cowrie shells used locally as currency. The Seventeen Provinces became the center of free trade in the 16th century, imposing no exchange controls. Trade in the East Indies shifted from Portuguese dominance to Dutch Republic control in the 17th century. The Spanish Empire developed regular trade links across both the Atlantic and Pacific Oceans during this era.
Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations in 1776. His work criticized Mercantilism and argued that economic specialization could benefit nations just as much as firms. David Ricardo advanced the theory of comparative advantage in 1817 with James Mill and Robert Torrens. They showed that free trade would benefit industrially weak countries as well as strong ones. John Stuart Mill proved that a country with monopoly pricing power could manipulate terms through tariffs. Milton Friedman later demonstrated that tariffs might be beneficial to a host country in specific circumstances but never for the world at large. The Great Depression ran from 1929 to the late 1930s causing a great drop in trade. Only World War II ended the recession in the United States. In 1944, 44 countries signed the Bretton Woods Agreement to prevent national trade barriers.
The World Trade Organization was created on the 1st of January 1995 to facilitate free trade. It mandated mutual most favored nation trading status between all signatories. The European Union lifted barriers to internal trade in goods and labour in 1992. The North American Free Trade Agreement took effect on the 1st of January 1994. The Doha round began in Doha, Qatar aiming to lower barriers to trade around the world. Talks have been hung over a divide between rich developed countries represented by the G20 and major developing countries. China joined the Asia-Pacific Economic Cooperation group in 1991 and the World Trade Organization in 2001. By 2008, China's two-way trade totaled US$2.56 trillion. International trade represents a significant part of GDP in most countries today.
