What type of government structure exists in Shingeki no Kyojin?


So I guess that the remaining human survivors formed a nation, but what form
of government exists in this nation? Who is the leader?




Seeing as there are mentions of a royal family being inside Wall Sina, it's
safe to assume that the government is monarchical in nature. However, I am
leaning towards a monarchical-parliamentary style, rather than just pure
monarchical or parliament. Reason being, even with hints at a king being the
head, the actions alone of the various commanders belie an amazing level of
independence. In addition, it's been seen a couple of times that they can be
summoned and tried in a public court, a trait that is definitely not purely
monarchical in nature (as kings alone judge in that event). The voting system
to approve a course of action mirrors a parliamentary set-up as well.
