George R.R. Martin’s detailed sketching of the world of Westeros is fascinating and his new book on the subject has gone into much more detail about it.

Reading the books and seeing references to historic kings such as Aegon the Unworthy - an obese, philandering king - and Baelor the Blessed, it is hard to picture the history of the world in your head.

We used the chronologies available on the superbly compiled Wiki of Ice and Fire to have a look at how long each Targaryen king ruled after Aegon I took over the Seven Kingdoms.

They are all present, from Viserys II, who was accused of poisoning the former King Baelor and then spending a fruitless year in charge (the shortest reign), to mad king Aerys II.

For a couple of kings the exact year of birth is inexact and a range is given and when that is the case we have given the mid-way point between the rough dates that are available.
