Phibun's second premiership was longer but plagued with [[political instability]], and there were numerous attempts to oppose his rule and remove him from power. Unlike his first premiership, Phibun faced noticeable opposition from people connected to the Free Thai Movement due to his alliance with the Japanese, including from within the military. Additionally, Phibun was indebted to the powerful Coup Group that had returned him to power.

On 1 October 1948, the unsuccessful [[Army General Staff Plot]] was launched by members of the army general staff to topple his government, but failed when discovered by the Coup Group. As a result, more than fifty army and reserve officers and several prominent supporters of Pridi Phanomyong were arrested.

On 26 February 1949, the [[Palace Rebellion]] was another failed coup attempt against Phibun to restore Pridi Phanomyong by occupying the [[Grand Palace]] in Bangkok and declaring a new government led by [[Direk Jayanama]], a close associate of Pridi. The civilian rebels were quickly ousted from the palace, but fighting broke out between military rebels and loyalists which lasted for over a week.

On 29 June 1951, Phibun was attending a ceremony aboard the ''[[Manhattan Rebellion|Manhattan]]'', a US [[dredge boat]], when he was taken [[hostage]] by a group of [[Royal Thai Navy]] officers, who then quickly confined him aboard the warship ''Sri Ayutthaya''. Negotiations between the government and the coup organizers swiftly broke down, leading to violent street fighting in Bangkok between the navy and the army, which was supported by the [[Royal Thai Air Force]]. Phibun was able to escape and swim back to shore when the ''Sri Ayutthaya'' was bombed by the air force, and with their hostage gone, the navy were forced to lay down their arms.

On 29 November 1951, the [[Silent Coup (Thailand)|Silent Coup]] was staged by the Coup Group and it consolidated the military's hold on the country. It reinstated the [[Constitution of Thailand#1932 constitution|Constitution of 1932]], which effectively eliminated the [[Senate of Thailand|Senate]], established a [[unicameral legislature]] composed equally of elected and government-appointed members, and allowed serving military officers to supplement their commands with important [[Minister (government)|ministerial portfolios]].

In 1954 Phibun allied Thailand further with the West in the [[Cold War]] by helping establish [[SEATO]].<ref name="brit" />

In 1956, it became clearer that Plaek, allied to Phao, was losing to another influential group led by Sarit which consisted of "Sakdina" (royalties and royalists). Both Plaek and Phao intended to bring home [[Pridi Banomyong]] to clear his name from the mystery around the death of King Rama VIII. However, the US government disapproved, and they cancelled the plan.<ref name="สมศักดิ์">{{Cite web|url=https://prachatai.com/journal/2010/10/31599|title=สมศักดิ์ เจียมธีรสกุล: พูนศุข พนมยงค์ ให้สัมภาษณ์กรณีสวรรคต พฤษภาคม 2500|website=prachatai.com}}</ref>
