Feudalism flourished in medieval Europe between the 9th and 15th century. Society was organised around three estates - Nobles, Clergy and Peasants. The borders of Kingdoms moved depending on victories in battles. The Revolutions of 1848 were also known as the Spring of Nations, with waves of new born Nations replacing the feudal system. To empower 'the people', stories had to be created around who 'the people' were. The first mentions of a common Slovene ethnic identity date to the 16th century. The first book in Slovene was written by a Protestant preacher Primož Trubar. Catholic means 'including a wide variety of things'. Protestant means what it says on the tin. Tools of central control like language and religion, can also be used to form borders not defined by land. Slovenia became independent of Yugoslavia in 1991. It has a population of about 2 million people, with 83% identifying themselves as Slovenes in a 2002 census.
