In 1311, after King Mangrai's death, his second son Grama, also known as Khun Hham, took the throne. However, internal conflicts arose when Mangrai's youngest son attempted to claim the crown, leading to power struggles and shifts in capital locations. Eventually, Saen Phu, Grama's son, established Chiang Saen as a new city around 1325. Following a series of short reigns, the capital was moved back to Chiang Mai by Pha Yu, Saen Phu's grandson. Pha Yu fortified Chiang Mai and initiated the construction of Wat Phra Singh in 1345 to honor his father, King Kham Fu. The temple complex, originally named Wat Lichiang Phra, expanded over the years with the addition of several structures.
