The history of Vietnam is one of heroes. Talented leaders, both military and otherwise have always emerged in times of trouble. 
There was one such time when the Song in the North was ready to launch their invasion whilst the Champa in the South was planning their revenge. The two enemies came together to bring their wrath on Đại Việt. 
Đại Việt was then a small country with a young king. Fortunately, the king had a team of talented advisors. Lý Thường Kiệt was one such person. He was a scholar as well as a military leader. He was loyal and dedicated to his country. He made peace with his enemy Lý Đạo Thành so that they could work together. As a man of both talent and virtue, Lý Thường Kiệt became a role model in the history of Vietnam.
