US occupation of Japan under General MacArthur- during this time the Constitution was written. It ended divine right rule, gave sovereignty to the people, a parliamentary govt, women's suffrage, local self-govt. It also renounced the war forever and the use of force. There were some war trials held but no great purge of military. Despite efforts at social and economic reform the power structure remained fairly conservative and Liberal Democratic party which held power after occupation was in reality a conservative grouping. With American help the Japanese economy had recovered by 1954.
