In 1010, King Lý Thái Tổ moved the capital from Hoa Lư to Đại La, which decision was explained in his Chiếu dời đô (Royal proclamation of moving capital): he saw a Rồng vàng (yellow dragon) fly around on the clear blue sky, so he changed the name of Đại La to Thăng Long, meaning "Vietnam's bright and developed future".
