Who were the Rosenbergs and what's so important about them?

The Rosenbergs, Julius and Ethel, were American citizens who were convicted of espionage for allegedly passing atomic secrets to the Soviet Union during the Cold War. Their trial in the early 1950s became a highly controversial and polarizing event, raising questions about the fairness of the judicial process and the extent of anti-communist sentiment in the United States. They were executed in 1953, making them the first American civilians to be executed for espionage, and their case continues to evoke debate over issues of justice, civil liberties, and the ethics of government actions during times of national security crises.
