A throne is the seat of state of a potentate or dignitary, especially the seat occupied by a sovereign on state occasions; or the seat occupied by a pope or bishop on ceremonial occasions.
"Throne" in an abstract sense can also refer to the monarchy or the Crown itself, an instance of metonymy, and is also used in many expressions such as "the power behind the throne". The expression "ascend (mount) the throne" takes its meaning from the steps leading up to the dais or platform, on which the throne is placed, being formerly comprised in the word's significance.
When used in a political or governmental sense, throne typically refers to a civilization, nation, tribe, or other politically designated group that is organized or governed under an authoritarian system. Throughout much of human history societies have been governed under authoritarian systems, in particular dictatorial or autocratic systems, resulting in a wide variety of thrones that have been used by given heads of state. These have ranged from stools in places such as in Africa to ornate chairs and bench-like designs in Europe and Asia, respectively.
