In 1920, the Spanish flu was raging its final battle against the world. By the end of 1920, it had infected a third of the world's population (an estimated 500 million people) and killed 50 million. Europe was seeing a rise of far-right radicalized political movements. In August 1920 the Nineteenth Amendment became part of the US Constitution giving women the right to vote, although it would be decades later when that right would be afforded to all women. The boom of economies in the 1920s would soon come to an end, with Black Tuesday leading to the Great Depression. Though many people didn't know it when the Paris Peace Conference ended, another world war was just around the corner. At the same time, the world witnessed great leaps in progress in science, technology and the arts. By the end of the 1920s, the world would benefit from Alexander Fleming's discovery of penicillin, the first liquid-fueled rocket, Gershwin's Rhapsody in Blue and Winnie-the-Pooh. And on 23 April 1920, the IP Federation (previously known as the less catchy Trade Marks Patents and Designs Federation) was established.
