Propaganda involves the deliberate spread of selective information or lies to shape public opinion and achieve a desired response. It can be traced back to leaders in ancient Greece using it to influence people. Throughout history, propaganda has often been used by governments and religious institutions to depict enemies, increase fear or hatred, and justify actions. Propaganda typically relies on exaggeration and simplification, making it generally untrue by presenting a one-sided or biased view of events and issues. It employs various media depending on the era, such as paintings, newspapers, radio, television, and now the internet, to spread its message.
