Concept
In many periodizations of human history, the late modern period followed the early modern period. It began approximately around the year 1800 and depending on the author, either ended with the beginning of contemporary history after World War II in 1945, or includes the contemporary history period up to the present day. Notable historical events in the late 18th century that marked the transition from the early modern period to the late modern period include – the American Revolution (1765–1791), the French Revolution (1789–1799), and the beginning of the Industrial Revolution around 1760. It took all of human history up to the year 1804 for the world's population to reach 1 billion; it only took 123 years later for the world population to reach 2 billion in 1927. From then to the close of the 20th century in 1999, the world population had tripled to 6 billion people.
