The
first
Siamese naval and national flag, used in the late
AyutthayaPeriod
and throughout the
Thonburi
Period, from 1680
until 1782,
i.e. at the beginning of the
RattanakosinPeriod.
This rather simple original
national flag
consists of
a plain red field
and is sometimes referred to as thong
sayaam, i.e.
‘flag
of
Siam’.
