The Thai Nation Party consisted of right wing conservatism, becoming the Chartthaipattana Party before ultimately joining the Democrat Party in 2008.
Thereafter, most MPs founded the Chartthaipattana Party (Thai Nation Development Party), which became the Thai Nation Party's successor. The party represented the rightist and pro-military wing of Thai politics during the relatively liberal and democratic years from 1973 to 1976. In November 1997, it joined a seven-party coalition supporting Democrat Prime Minister Chuan Leekpai.
