In this video Heimler explores Unit 4 Topic 1 of the AP World History curriculum which spans from 1450-1750. The main idea in this Unit is the expansion of sea-based (maritime) empires.

In Topic 1 Heimler explains the maritime technology that made the expansion of sea-based empires possible. There were developments in tools like the astrolabe, the magnetic compass, astrological charts, and maps of wind patterns.

Also new trade ships were created. The Portuguese created the caravel and the Dutch created the fluyt. Both ships used the lateen sail and smaller form factors to increase their abilities to expand trade in the age of exploration.
