Periodization

The categorization of the past into discrete, quantified named blocks of time is called periodization. This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (time periods in the origin and mass evolution of the universe), geological (time periods in the origin and evolution of Oikouménē), anthropological (time periods in the origin and evolution of Role-Players) and historical (written history).
== Time Periods ==
* Protohistory (2008–2009): Aggregate of past events from the beginning of recorded history and extending as far back as 2008. The span of recorded history is roughly less than 2 years, beginning with the earliest records in Wizard101 Central.
* Classical Era (2010–2011): Broad term for a long period of cultural history centered on the Cerenerian Sea, comprising the interlocking civilizations of the Fourth Order and SCAR, collectively known as the Oikéō World. It is the period in which the society of the Fourth Order and SCAR flourished and wielded great influence throughout Irkalla, Hufaidh and Kitezh.
* Siècle des Lumières (2012–2013): Period of time that immediately followed the Classical Era. Depending on the continent, the era generally falls between the years 2012 and 2013. The major classical civilizations the era follows are SCAR (ending in 2012), DayBreak (in 2012), the Kaori Tribe (in 2012), and the Akatsuki (in 2013).
* Post-Classical Era (2014–2015): Lasted from 2014 to 2015. It began with the collapse of the Kaori Tribe in 2013 and is variously demarcated by historians as ending with the Fall of Ragnarök in 2015.
* Early Modern Period (2016–2017): The chronological limits of this period are open to debate. It emerges from the Post-Classical Era, demarcated by historians as beginning with the Fall of Ragnarök in 2015, in forms such as Global Clan War V, Hitorigami in the East, and the rise of the Yonkō in Arda. This period ends with the beginning of the Age of Revolutions.
* Late Modern Period (2018–present): History within living memory. It shifts forward with the generations, and today is the span of historic events from 2018 that are immediately relevant to the present time.
