国家再建最高会議
Initially, a new administration was formed from among those military officers who supported Park. The reformist military Supreme Council for National Reconstruction was nominally led by General Chang. Following Chang's arrest in July 1961, Park took overall control of the council. The coup was largely welcomed by a general populace exhausted by political chaos. Although Prime Minister Chang and United States Army General Carter Magruder resisted the coup efforts, President Yun sided with the military and persuaded the United States Eighth Army and the commanders of various ROK army units not to interfere with the new government. Soon after the coup, Park was promoted to Lieutenant General. The South Korean historian Hwang Moon Kyung described Park's rule as very "militaristic", noting right from the start Park aimed to mobilize South Korean society along "militaristically disciplined lines". One of Park's very first acts upon coming to power was a campaign to "clean up" the streets by arresting and putting to work all street kids and vagrants.
