Syngman Rhee
Syngman Rhee (, ; Lunisolar calendar , 1875 – July 19, 1965) was a South Korean politician, the first and the last Head of State of the Provisional Government of the Republic of Korea, and President of South Korea from 1948 to 1960. His three-term presidency of South Korea (August 1948 to April 1960) was strongly affected by Cold War tensions on the Korean Peninsula.

After Korea was liberated from Japan on 15 August 1945, the Special Committee for Prosecution of Anti-National Offenders (banmin teukwi, 반민특위) had been established to purge and prosecute the pro-Japanese who worked for the Japanese colonial government. However, all efforts were hampered and dissolved by Dr. Syngman Rhee, the first president of South Korea, who had to depend on the pro-Japanese to establish his regime. 
As a result of Dr. Rhee's political schemes, many pro-Japanese as well as Hong Jin-Ki could cut their ways of what they have done during the Japanese rule, resulting in the empowerment and reinstatement of the pro-Japanese officials, armies and police.
