This book represents an attempt to enter the area previously unpopular among political science researchers. The research of parties from within represents a very demanding and, very often, hardly feasible project. Parties, by their definition, are closed units, distrustful towards external entities. Thus, in a scientifically based manner, the research of this issue is very demanding. This book reveals the results of this research in Montenegro, the country where such a type of research was never done before. On the one hand, Montenegro represents a very stimulating case when we speak about party system research. This was, and still is, a rare example of a multi-party system with one dominant party, which holds this position since the introduction of multipartism.
