The idea of human rights originated from ideas found in religion and philosophy in Western Europe. The modern Western idea of human rights started in the European Enlightenment. In the 16th century, some people started suggesting that everyone had the religious and political right to choose their religion and their leaders. This sort of thinking was important in the English Civil War. After the war, the philosopher John Locke argued that people should have a certain set of human rights. These ideas were also important in the American revolution and the French revolution in the 18th century.
