How do you think life in the 1950s was shaped by world events of the early part of the 20th century?

Although you don't specify this in your question, I'm going to assume that you are mainly interested in how life in the United States in the 1950s was shaped by early-20th-century world events. The dominant world event that shaped life in the fifties was World War II, which took place in the first half of the 20th century. World War II, in turn, came about because of earlier events that led up to it, such as World War I, controversial provisions in the Treaty of Versailles at the end of the war, and the Great Depression, which took place between World War I and World War II.
The postwar era of the '50s was marked by economic prosperity and the confidence that the future would be full of peace and plenty. Many returning veterans were able to find work, unemployment was low, and the GI Bill helped subsidize the purchase of homes in newly-rising suburbs. The stability of family life prompted what became known as the "baby boom," during which record numbers of babies were born. Family life was typically conservative. Usually men would hold jobs and bring income to the home, while women were expected to keep house and raise children. This gender bias was an issue that created dissatisfaction among women that would erupt later. In the aftermath of the Great Depression and World War II, though, people and families craved stability and security.
Before World War II, black people were usually relegated to low-paid menial jobs. In 1941, President Franklin D. Roosevelt opened up national defense positions and other government jobs to all races. The military was segregated during the war, but afterwards, the civil rights movement began to gain momentum.
The Cold War was another major factor that affected life in the fifties. It came about due to events earlier in the century such as the Russian Revolution, Russian involvement in World War II, and agreements made between Franklin Roosevelt, Winston Churchill, and Joseph Stalin at the close of the war. The Cold War created a background of paranoia that profoundly affected American society and politics in the '50s.
We can see, then, that events in the early part of the 20th century such as World War I, the Russian Revolution, the Great Depression, and World War II all fundamentally shaped life in the 1950s.
