Did you know? The Gaya Federation
Although it is called the Three Kingdoms Period, we should not forget about the Gaya Federation! Although it was a confederacy of small city-states in the Nakdong River Basin (southern coast of the peninsula), the people of Gaya were well-known for their maritime trade and impressive iron-working.
This fun fact is taken from a page of our Week 1: Travel to the Three Kingdoms session.
