Chiang Mai Province (Thailand) (original) (raw)

According to the Thai Ministry of Interior in 2000, the flag of Chiang Mai province is blue with a representation of the main elements of the provincial seal in the middle of the flag on a pale green disk with a red outer and a yellow inner border, and the name of the province in red on a yellow label on the bottom of the disk.

There was a kingdom of Lanna (Lan Na) 1259-1892 (royalty continued to 1939) and it has been reported that it had a banner or at least that the ruler had one.

There were also principalities that might have had flags at:
Khelang Nakorn (from 1892 Lampang province), royalty ended 1925;
Lamphun 1775-1892 (royalty ended 1943);
Nan to 1892 (royalty ended 1931)
Patani (from 1902 Pattani).

It would be interesting to see if there was more history about the flags of these regions.
