Lessons (8)
- Where did the silver flowHolding silver and being able to use it are different. If you borrowed before it landed, it passes straight through.
- Who was it that dug the silverExisting institutions are easily repurposed. The name may stay while content and aim have changed.
- Enemies gather along the silver roadThe longer the road, the costlier the guard. Guarding silver can cost more than the silver.
- What reservations "the birth of world trade" needsThe more striking the sentence, the more it needs whose thesis it is. That alone makes it safe to use.
- The Man Who Measured the Road — Hamilton's LedgerFour hundred years later, an economic historian measured the breadth of the Silver Road from the Seville registers. Unregistered amounts are not included.
- The Cupellation Masters of the Eastern Island — The Silver of IwamiJapanese silver, once said to account for one-third of the world's supply. The introduction of refining technology connected the island to the Silver Road.
- Sails of the Pacific — The Merchants of the Manila GalleonFrom Acapulco to Manila. The exchange of silver and silk transformed the Pacific into a single trade route.
- What Remains at the End of the Road — From Silver Dollar to YenAt the end of the Silver Road, there is no silver. What remained were the names: dollar, yen, and yuan.

The reason silver flowed to China lies in this point. It is written here that the Single Whip Reform, which consolidated various taxes and labor services into a single payment in silver, took fifty years to spread throughout the country after its proposal in 1530. - The Magic of the Patio Mexico 1554– Almadén → Veracruz
This is about what the miners lacked. Please note that the mercury required for the patio process was a royal monopoly, and the amount supplied directly determined the upper limit of silver production. Also, see that the Crown measured production by the rule of thumb of one marco of silver per pound of mercury. - A country with no mines had enough silver India 16th–17th centuries Caravans of the Near East and Central Asia
The silver road was not only across the Pacific. Please note that it reached India via two routes: a land route through caravans in the Near East and Central Asia, and a sea route carried by company ships. Also, see that historians have written that Spain ceased to be the greatest beneficiary of New World silver.
