The change that was so celebrated at the beginning of the new century began to take an ugly turn, as women, immigrants and other minorities began to expect and then demand a better place in society. Women wanted the vote. Black people, the children and grandchildren of slaves, wanted the full measure of their freedom and demanded equality as citizens. And immigrants, fed up with endless poverty, gathered up their things and headed for greener pastures in America, England, Australia, and other places where they were free to start over. Around the world, people who had felt downtrodden and discriminated against began to rebel. Then in 1914, Gavrilo Princip, fired the shot that killed Archduke Franz Ferdinand of Austria-Hungary, and started the bloodiest, most expensive war in the history of the world. It was the first mechanized war, the first air war, the first war to cost millions of lives, and the first war ever to be recorded on film.
