From 1941 to 1944, Greece endued the devastating effects of World War II, including military invasion, occupation, and fierce fighting with Greek Resistance groups, which all caused unprecedented damage to the country's already-underdeveloped infrastructure and economy. Forced loans demanded by the occupying regime severely devalued the Greek drachma, while the end of the war gave way to a bitter civil war that lasted until 1949. By 1950, the relative position of the Greek economy had dramatically deteriorated: the income per capita in purchasing power terms fell from 62% of France's in 1938 to about 40% in 1949, less than a decade later.
