It was established in 2018 by Chuan Chuchan (ชวน ชูจันทร์) and Suchart Jantarachotikul (สุชาติ จันทรโชติกุล) as a "party of power" to support Prayut Chan-o-cha in 2019 Thai general election.

[22] Although Palang Pracharath came 2nd in the polls, it successfully nominated Prayut and formed a coalition government with votes from 249 senators, and MPs from the Democrat and Bhumjaithai parties.

Prior to the 2023 general election, several former members of Palang Pracharath split off to form the United Thai Nation Party, and were later joined by Prayut Chan-o-cha.

[29] Since its founding, the party has been widely criticized for its leaders' close relationship to the junta and alleged abuse of their cabinet positions to fund-raise and campaign for Palang Pracharath.

In late January, 2019, after the publication of the royal decree formalizing the election, four Prayut cabinet ministers resigned from their positions to campaign full-time.

[33] It adopted typical populist policies, like cheap housing, debt relief for both laborers and farmers, improving the minimum wage, and payments for newborns and mothers.

[33] On 29 January 2019, all four Prayut cabinet ministers (Uttama Savanayana, Suvit Maesincee, Sontirat Sontijirawong and Kobsak Pootrakool) resigned from their government positions after months of criticism.

Palang Pracharat leader and Industry Minister, Uttama Savanayana, denied the allegations and said that the cash handouts are intended to help the poor and the needy.

Concerns were also raised that Palang Pracharath leaders, who are also currently serving as cabinet ministers, used their government positions to solicit funds, which would be illegal.

On this issue, former EC commissioner, Somchai Srisutthiyakorn, stated that if the party leaders used their personal funds to purchase the tables, they would need to be investigated for their unusually high wealth.

[58][60][61] However, if they purchased tables for other individuals, in effect, hiding their identities in financial disclosures, they may be breaking election, bribery, and money laundering laws.

[62] Meanwhile, party secretary-general and commerce minister, Sontirat Sontijirawong, stated the map is inauthentic and accused Isranews of spreading false news.

In December, a Yasothon resident alleged that people attempting to collect their state welfare cards were given documentation and forced to join the Party.

In late January 2019, Nattawut Saikua, a Thai Raksa Chart politician raised concerns about Palang Pracharath using state welfare cards to solicit support from voters.

He cited several reports of state welfare card owners receiving phone calls from individuals asking them to vote for Palang Pracharath to ensure continued support for the program.

[65] Although Palang Pracharat is a newly established political party, it is quite well-known because of its perceived relationship to Prime Minister Prayut Chan-o-cha and the junta.
