The concept of the First World originated during the Cold War and included countries that were generally aligned with or on friendly terms with the United States (including all NATO countries) and were generally identified as non-theocratic democracies with primarily market-based economies. While there is no current consensus on an exact definition of the term, in modern usage, "First World country" generally implies a relatively wealthy, stable and functional non-theocratic democracy with a reasonably well educated population, or just any developed country.
