Thailand: History


Here, this is a Thai History page.

The first unified kingdom of Thais is Sukhothai started in 13th century. However, before the era, times changed in the flow of a long thousand years: the history of the prehistoric age, Haripunchai kingdom, Lannathai kingdom, the Khmer culture in Northeast Thailand and so on.

Let's study with me. I'm going to inquire the history more.



 Kingdom of Thailand

Thailand is a kingdom.
The present king is Rama 9.
(King Bhumibol Adulyadej (Rama IX) the Great)
(The left photo is from the factory in Ayuttaya that Queen Sirikit manages.)


It appears that the country was being unified around Sukhothai period in 13 century under kings.
Even while another countries around Thailand got colonized by England or France, Thailand kept itself independent.

 Buddhist Calendar

In Thailand, they use the Buddhist calendar, not the Gregorian calendar used in western countries.
(Japan had been used the traditional lunisolar calendar up to 1872, but has changed to the Gregorian calendar since then.)


- Buddhist Calendar (BE) : Gregorian Calendar (AD) + 543 years
- Gregorian Calendar (AD) : Buddhist Calendar (BE) - 543 years
The year 2014 in the Western Calendar is 2557 in the Buddhist Calendar. (2014 + 543 = 2557)
When you see a year in the Busshist Calendar in Thailand, minus 543 from it.

By the way, our wedding ceremony was held in Thailand and I found the year showing on the wall by the Buddhist calendar. I was wondering what it was then. :-D )
