After a series of disastrous military campaigns against Goguryeo on the Korean peninsula, ended in defeat by 614, the dynasty disintegrated under a series of popular revolts culminating in the assassination of Emperor Yang by his minister, Yuwen Huaji in 618. The dynasty, which lasted only thirty-seven years, was undermined by ambitious wars and construction projects, which overstretched its resources. Particularly, under Emperor Yang, heavy taxation and compulsory labour duties would eventually induce widespread revolts and brief civil war following the fall of the dynasty.
