Queen Jindeok (r. 647–654) ascended the throne and became the Silla's second Queen regnant after Queen Seondeok. The last monarch from the ranks of the Seonggol, the highest class in the Silla's unique caste system, her real name is Seungman. Her father was Kim Gukban, who was King Jinpyeong's youngest brother, and her mother was Lady Wolmyeong. During her seven-year reign Queen Jindeok's primary concern was foreign policy. With the help of general Kim Yushin she was able to strengthen Silla's defenses and greatly improve her kingdom's relations with Tang China. Those efforts laid the foundation for the unification of the three kingdoms (Silla, Baekje, and Goguryeo).
