Harshavarman II

Harshavarman II was an Angkorian king who ruled from 941 to 944. He succeeded his father in 941; however, his reign at Koh Ker was brief and "characterized by conflict". His cousin, Rajendravarman II, wrestled the power away from him and moved the capital back to Yashodharapura. He died in 944 and received the posthumous name of Brahmaloka.

Battle of Koh ker

After King Hasaravarman II had reigned for only two years, in 944 CE, the Sailendra dynasty of the Malay Peninsula sailed up the Mekong River, attacked the capital of Koh Ker , captured King Hasaravarman II, beheaded him in Srivijaya , and declared a new empire, the Chola dynasty , which ruled the capital of Koh Ker for three years. His younger brother Rajendravarman II drove the Chola army back in 947 CE and declared himself king at that time.
