In November 1989, Czechoslovakia returned to a liberal democracy through the Velvet Revolution. However, Slovak national aspirations strengthened (Hyphen War) and on 1 January 1993, the country peacefully split into the independent countries of the Czech Republic and Slovakia. Both countries went through economic reforms and privatisations, with the intention of creating a market economy. This process was largely successful; in 2006 the Czech Republic was recognized by the World Bank as a "developed country", and in 2009 the Human Development Index ranked it as a nation of "Very High Human Development".
