Yi Sun-sin was born the fourth son of a little known nobleman in Hanyang (Seoul), Joseon (Korea) in 1545. When he was a child in the mid 16th century it was relatively calm on the peninsula, but it did not begin or end that way. Soon the future of Korea would be hanging by a thread and it would be desperate for heroes. Little did he know that his determination to pursue a life in the military would put him in position to alter the course of history for his people and for Asia. This first episode in the Yi Sun-sin series of the Korean Heroes podcast is the story of this great man’s humble beginnings as we set the stage for the Japanese invasion of 1592: The Imjin War.
