Jayavarman I was the last ruler of the united Chenla kingdom, reigning from around 657 to 681, and played a crucial role in consolidating Khmer royal power before the fragmentation of Cambodia.

Biography
Jayavarman I (Khmer: ជ័យវរ្ម័នទី១) succeeded his father Candravarman and was the great-grandson of Isanavarman I. His rule marked a transitional period in early Cambodian history, leading toward the later emergence of the Khmer Empire. His capital, Purandarapura, is thought to have been near the modern Angkor region. Jayavarman I’s reign saw the consolidation of Khmer authority over areas previously influenced by Funan culture, though persistent conflict with local overlords remained.
Succession and Legacy
Jayavarman I left no male heir, resulting in a succession crisis and the division of Chenla. His daughter, Queen Jayadevi, seems to have become ruler after his death, representing a rare period of female leadership in ancient Cambodia. Numerous inscriptions from his reign have been found throughout Cambodia, reflecting the extent of his influence.
