Campbell and Carr’s Weekly Review Session #4

Technology

I. Neolithic Revolution

a. Domestication of plants and animals

b. Increased food supply, allowing permanent settlements, allowing civilization

c. Pottery, writing systems (allow transmission of knowledge), organized religion, government, social classes

d. Agriculture

i. Irrigation – small canals/channels that bring water from river to crops

d. Steel - reserved for weapons until Industrial Age and Bessemer process

(cheaper, more

reliable high quality steel) make steel the main metal for industry

III.

d. Europe begins adopting

i. Break down city/fortress/castle walls

ii. New styles of fortress required, too $$$ for nobles

iii. Guns and material eliminate superiority of $$$ knights and armored soldiers 1. Punch through armor rendering it mostly useless

iv. Anyone can be trained to use guns, non-noble/knight armies

v. Absolute rulers and kings will use taxes to create standing armies of gunners and pikemen

1. Centralization of power e. Age of Exploration/Imperialism

i. European’s rapid development of gunpowder weapons and technologies allows them to have a military edge over most other peoples.

ii. Allows Europe to conquer South America (New World) and Colonize/create Empires in India, Africa, and China

V.

Age of Exploration Inventions

a. New Technologies allow Europeans to expand their exploration and eventual domination of parts of the world

b. Lateen Sails – Triangular sails, allow sailing in little to no wind or even when wind is against you. Developed/refined by Portuguese and spread through Europe

c. Caravel – ship with Lateen sails, deep draft, able to sail over the Atlantic, Columbus’s ships

d. Magnetic Compass – invented by Chinese, spread through trade/diffusion to Muslim kingdoms and from them to Europe, aids in navigation (going where you want to)

e. Astrolabe- Uses the sunlight to find out your latitude, aids in navigation

(3)

VI. Printing Press
