Rattanakosin came into being when King Rama I ascended the throne in 1782. He decided to establish the new capital on the east bank of the Chao Phraya River for better security from Burma. King Rama I was determined to build a new capital to revive the glory and splendor of old Ayutthaya. The new capital was proclaimed and hence began the Rattanakosin era or Bangkok period under the glorious reign of the Chakri Kings. - (PF.5293)
