Are honorifics used for dead people?


Are honorifics used for dead people? For example, would チンギス・カン have something
after the name (presumably not just a mere さん!) when you're not referring to
the [dish](http://en.wikipedia.org/wiki/Genghis_Khan_%28Hokkaido_dish%29)?




Since honorifics generally apply when you are interacting directly with that
person, they usually aren't used for people that have died (Maybe spiritual
mediums do something different because they are supposedly 'interacting
directly' with the deceased, but I don't know).

Think of great people from Japanese history: 織田信長（おだのぶなが） 徳川家康（とくがわいえやす）
聖徳太子（しょうとくたいし）, all of them are referred to just by their name. Deceased
former prime ministers are simply referred to by their name. Deceased Emperors
are called by their reign (i.e. what we call Emperor Hirohito is just
昭和天皇（しょうわてんのう） the Showa Emperor in Japanese), while the current living
Emperor Akihito is referred to in Japanese by 天皇陛下（てんのうへいか） or His Majesty the
Emperor.

Going closer to home, people refer to their deceased relatives the same way
they did while they were alive. Buddhist beliefs give the deceased a new name
for the afterlife, but I have never heard of this new name actually being used
to refer to the deceased.
