It is argued in this paper that the non-formation or non-growth of democracy in the Middle East is related to geopolitical centrality. The network analysis of Iran and Saudi Arabia in terms of geopolitical centrality indicates that the high geopolitical centrality of these two countries in the existing geopolitical sub-networks at this region is one of the important barriers against realization and promotion of democracy. In Iran before 1979 Revolution, its high centrality under geopolitical sub-networks of security and the west and also after the 1979 Revolution, its high centrality in several ideological sub-networks have made slower Liberal democratic growth in this region.in contrast In Saudi Arabia, high centrality of this country since 1980s in ideological sub-networks and its role in geopolitical sub-networks of west and security on three past decades has hindered formation of Liberal democracy in this country..
