The 1940s were seen as a transition period between the radical 1930s and the conservative 1950s, which also leads the period to be divided in two halves:
The first half of the decade was dominated by
World War II, the widest and most destructive armed conflict in human history. So consequential was this event and its brutal aftermath that it laid the foundation for other major world events and trends for decades to follow. This war was also the first modern civilian war.
The second half period marked the beginning of the East-West conflict and the
Cold War, together with major social upheaval caused by the destruction of the war, the large number of refugees, and soldiers returning home and demanding government recognition for their sacrifice, especially in colonies of European countries, many of which gained independence.
