"European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya, which became a regional power by the end of the 15th century."

This statement is grammatically incorrect, employing the wrong tense for the latter portion, and needs to be corrected. As constructed, the second clause must be a subsequent event from the first clause. This creates a contradiction where becoming a regional power by the end of the 15th century supposedly happens after a 16th century date. The correct version should be "...which had become a regional power by the end of the 15th century." — Preceding unsigned comment added by 2600:4040:B07B:9700:8004:287A:CE3B:B18F (talk) 15:33, 21 September 2025 (UTC)[reply]

The Thai people have called their country by (the Thai language equivalent of) "Thailand" for many centuries. Siam began as an exonym, and was popularized by early European explorers. Please correct this. I've deleted the phrase shown in title topic to encourage prompt attention. Jamesdowallen (talk) 07:20, 25 July 2025 (UTC)[reply]

Your explanation indicates that the statement is correct. Thailand was historically known as Siam. The statement does not say that it was universally known as Siam always and forever from the beginning of time. All names of a place used by a foreign speaking people are inherently exonyms. Even when the foreign name derives from the native name, it's almost always a different actual word. In any event, your claim is wrong anyway. As the etymology section of this article points out, the closest Thai language equivalent of "Siam" seems to have been used in ancient times by the Khmers to refer to the people of central modern day Thailand. And the etymology of "Thai" and "Siam" is clearly linked. Use of "Siam" is therefore an example of pas pro toto, just like the names Holland and Persia had long been used to represent their respective countries as a whole. — Preceding unsigned comment added by 2600:4040:B07B:9700:8004:287A:CE3B:B18F (talk) 15:55, 21 September 2025 (UTC)[reply]

In the article, the plural of "coup d'état" should be "coups d'état", not "coup d'états". ~2025-43894-29 (talk) 06:43, 30 December 2025 (UTC)[reply]
