According to their description this area would not only include present-day Greece, but also Albania, North Macedonia and the southern half of Bulgaria, an area that included all the areas ruled by the Macedonian Kings, in addition to those of classical Greece incorporating most of the Orthodox populations of the Balkan peninsula, which was during that time under Ottoman rule. They concluded that the 'Greek lands' are located in a privileged geographic location at the crossroads of three continents: Europe, Asia and Africa, however, as the Ottoman administration was incapable of reinforcing the rule of law, economic activity couldn't flourish. Thus, they addressed the political and economic instability of the Ottoman Empire that struggled to maintain control over different ethnicities and huge territories. As a consequence of that lack of control, many Greeks were impelled to seek protection outside the Ottoman Empire, while the ones that had not abandoned their lands, suffered under a terrible Ottoman regime, and had no educational rights. Reflecting a new revolutionary era in the European history after the outbreak of the French Revolution, the authors expressed sharp social criticism, castigating the corruption of the church authorities, the idleness of the monasticism, and popular superstition. They also appealed for reform of the language, education, and change to the social mores as a way to overcome backwardness and to renew people's mentality with a more western view. They claimed that Greece is positioned within a Europe defined by the dynamics of political reforms from old and corrupt monarchical regimes to new republican communities. The modern innovative spirit of "Geographia Neoteriki" was also expressed in the use of a lively and malleable vernacular (Demotic) language with very few ties to the katharevousa, a more archaich form of Greek, which was commonly used by most Greek scholars of that time. The book introduced a number of new ideas in the field of human geography and social organization models, that had been developed in the western world during the 18th century. Among the sources that the authors used to compose "Geographia Neoteriki", were the "Géographie Moderne" by Nicolle de La Croix, the "Géographie Ancienne", and the "Géographie Moderne", which were part of the "Encyclopédie Méthodique" by Charles-Joseph Panckoucke. Additionally, the authors had personally examined the areas described in the work. This element served both as the work's primary organizing mode as well as the basis for their historical approach.
