The 1st ever edition was played in 2009 by the following regional league winners; Chiangrai United, Raj Pracha-Nonthaburi, Narathiwat, Loei City and Samut Prakan.
Raj Pracha-Nonthaburi duly won the first ever championship and were followed by early pace setters Chiangrai United, who tended to stall once promotion was achieved and deep south team Narathiwat who claimed promotion in the deciding game in a 0-0 draw with Samut Prakan who also could have achieved promotion going into the last match day.
