1000 CE as Turning Point: The Birth of Globalization? - New Technology

8 important questions on 1000 CE as Turning Point: The Birth of Globalization? - New Technology

What did Arab commerce help with regarding globalization?

- Arab commerce helped generate significant improvements in shipping technology, utilizing ideas from China and Southeast Asia as well as the Middle East.
- Movement of bulk goods, like grains and metal ores, became possible as never before. Along with the sheer expansion of east-west trade, the new shipping capacities provided another step in the network from any of the patterns that had been established before.

What new advantages did Arabs gain when they conquered Persia?

Arabs gained new advantages as they learned navigational techniques and ship designs from Persian traders after their conquest of that region.

What is the astrolabe? Who came up with it?

- Arabs picked up and improved the astrolabe, a device initially introduced in classical Greece, translating Greek manuscripts on the subject into Arabic by the eighth century.
- Astrolabes allowed the calculation of heights of mountains or human structures, as well as accurately measuring the position of objects in the sky. Astrolabes facilitated land-based as well as seagoing transportation, determining latitude and longitude though only approximately.

What made the magnetic compass better than the astrolabe?

The dissemination of the magnetic compass was really important. Here was an instrument that could indicate direction in virtually any circumstance, in contrast to the astrolabe which greatly aided positioning but was of little use in a stormy sea because it needed to hang freely to find the horizon.

Who invented the magnetic compass? What is it about?

- It's clear that the instrument originated in China at some point in the Han dynasty.
- It was the navigational use, becoming very clear by the seventh century, which was really important. By that point, the Chinese knew that an iron needle could be magnetized by rubbing it with magnetite ore, and they were also able to use intense heat to magnetize a needle in a north-south direction.
- The needle could then be floated in a bowl of water, where it would spin until it pointed.

What was a crucial development in shipping around 1000CE, next to the magnetic compass?

- A crucial development was the growing use of the lateen sail, both in the Indian Ocean and the Mediterranean. Lateen sails were triangular, which allowed them to be maneuvered to catch winds coming from various directions; and they could be placed at the front and rear of a vessel.
- Both speed and flexibility benefited greatly from this innovation.

What are dhows? What did they do? What did dhows allow for Arabs?

- Arab ships, called dhows, came to dominate Indian Ocean trade by 1000CE.
- They were relatively large boats with transverse watertight bulkheads reducing - though as we have seen, not eliminating - the danger of sinking.
- Dhows had two masts, each with a lateen sail. Wicker rail prevented ways from breaking over the ship's bulwark.
- In Arab hands, the dhows allowed faster and longer trips and the transport of bulk cargoes such as foodstuffs, metals and manufactured goods - like the Chinese porcelain that was becoming so widely sought after.

What shipbuilding innovation came from the Chinese?

Chinese junks had been introduced in the Han dynasty. Their wider deployment and growing sophistication dated to the Song dynasty and its great trading outreach.
