“…The post-bipolar world produced numerous challenges in the field of the theory of a state which political geography reflects on (e.g. Cox, 2002: 243--273;Kuus and Agnew, 2008;Corbridge, 2008;Silvay, 2010), be it the question of territoriality (Taylor, 1994;Agnew, 2010;Reid-Henry, 2010), or the problems of sovereignty (Agnew, 2009;Coleman and Grove, 2009;Mountz, 2013), unequal development of states (Cox, 2002: 275-322;Sheppard, 2012), failing states (Luke and Ó Tuathail, 1997;Hastings, 2009;Ištok and Koziak, 2010), and separatism (Agnew, 2001;Baar, 2001;O'Loughlin and Ó Tuathail, 2009;Riegl and Doboš, 2014). The political-geographical research on de facto states is connected to the research on separatism, as well as on sovereignty (Flint, 2002: 394-395).…”
