Enthronement
In 1645, Crown Prince Sohyeon returned to Joseon alone, in order to succeed Injo to the throne and to help Injo to govern the nation. However, he often came into conflict with Injo, who disliked Sohyeon's open view of European culture and diplomatic views of the Qing Dynasty. Soon he was found dead at the King's room, and buried quickly after a short funeral. Injo also executed Sohyeon's wife who tried to find out the real reason for her husband's death. Legends say that Injo killed his own son with an ink slab that he brought from China.
The incident made Hyojong, the next-in-line, the new crown prince, and he was called back to Joseon. When King Injo died in 1649, Hyojong inherited the throne, becoming the 17th monarch of Joseon.
