Editing Head of state (section)

===Loss===
Apart from violent overthrow, a head of state's position can be lost in several ways, including death, another by expiration of the constitutional term of office, [[abdication]], or resignation. In some cases, an abdication cannot occur unilaterally, but comes into effect only when approved by an act of parliament, as in the case of British King [[Edward VIII]]. The post can also be abolished by constitutional change; in such cases, an incumbent may be allowed to finish their term. Of course, a head of state position will cease to exist if the state itself does.

Heads of state generally enjoy widest inviolability, although some states allow [[impeachment]], or a similar constitutional procedure by which the highest legislative or judicial authorities are empowered to revoke the head of state's mandate on exceptional grounds. This may be a common crime, a political sin, or an act by which the head of state violates such provisions as an established religion mandatory for the monarch. By similar procedure, an original mandate may be declared invalid.
