"In many periodizations of human history, the late modern period followed the early modern period. It began approximately in the mid-18th century and depending on the author either ended with the beginning of contemporary history after World War II, or includes that period up to the present day. Notable historical milestones included the American Revolution, the French Revolution, the Industrial Revolution, and the Russian Revolution. It took all of human history up to 1804 for the world´s population to reach 1 billion; the next billion came just over a century later, in 1927." - (en.wikipedia.org 22.01.2022)
