Hundreds of thousands of soldiers from Britain and its empire died in the fields of Flanders during World War I. Britain didn’t mean to go to war, but German naval ambition and the invasion of Belgium forced Britain to enter the war. The huge British navy, its experienced Guards Regiments, and its industrial wealth proved decisive in the conflict. Trench warfare and industrial weapons produced an incredibly deadly and miserable war that devastated British communities. In this video, Nick Dennis explores the impacts of the war on Britain through conversations with two experts on Britain’s naval and military history.

We might think of the Afro-Eurasian trading system as an archipelago of trade—a chain of overlapping trade circuits and trading cities. In the thirteenth century, England was at the far end of this archipelago of trade. England’s most valuable trade good was wool, which it exported to Western Europe and the Mediterranean. The best wool in Europe came from England, and England’s economy ran on wool. The wool trade helped empower an English merchant class. By the fourteenth century, these merchants organized into a guild that gave them more power and privileges in English society.

The Industrial Revolution transformed life on Earth more than any event since the Agricultural Revolution. In this video, Nick Dennis explores how industrialization changed our lives and why it started in Britain. There are many reasons that industrialization took off in Britain, including its abundance of coal, its geography and environment, and its economy. Still, many believe British industrialization would have been impossible without resources extracted from its colonies.
