The document discusses the expansion of democracy globally over the past century. It provides details on the establishment of democracy in different regions at different times, including early democracies in Europe and the Americas in the late 19th/early 20th century. Decolonization in Asia and Africa in the mid-20th century led to many new democracies, though some later faced military coups. The fall of communism in Eastern Europe and Soviet Union in late 1980s/early 1990s expanded democracy further. However, full democracy has still not been achieved in all countries.
