therefore the article will pay more attention to the emergence and evolution of the two Thai political protest factions. The aim of the article is to present factual information on the circumstances that led to the extensive antagonism between the red shirts and yellow shirts (as well as the anti-Thaksin groups). The article is divided into four main parts: the rise and fall of the populist Thai Rak Thai Party (2001-2006); the military junta, yellow shirts and street politics (2007-2008); the red shirt uprising and the government’s crackdown (2009-2010); and the resurrection of the Thaksin regime and the new face of protest movements (2011-2014). The information in this article came from the author’s collection of daily news clippings and memos or reflective notes between 2011 and 2014. The materials were mostly retrieved from online media, for both international and Thai contents.
