The 18th century, a period of hundred years from 1701 to 1800, is widely regarded as the ‘Age of Enlightenment.’ The ideas of Enlightenment, which were primarily based on the scientific revolution of the previous century, weakened the socio-political influence of the monarchy. It led to several significant political revolutions around the world.
The century saw American colonies breakout from the shackles of European colonial powers, while many new territories were gained in Asia. It also witnessed the rise of new kingdoms at the expense of old and worn out empires in Europe and Asia.
In this overview article, we have tried to compile every significant event around the world that occurred in the 18th century. For simplicity, we have given a year-by-year description, which is, in turn, organized by decades.
