A model for the emergence of geopolitical division

TL;DR

This paper introduces a simple model based on competitive dynamics that explains the emergence of geopolitical divisions and the typical locations of capitals within countries, aligning with observed geographical patterns.

Contribution

The work presents a novel, geometrically inspired model that reproduces key features of geopolitical division and capital placement, offering an evolutionary perspective.

Findings

Model successfully reproduces features of geopolitical division

Explains why capitals are often located away from borders and coasts

Provides insights into the spatial distribution of capitals within countries

Abstract

In this work, we present a model based on a competitive dynamics that intends to imitate the processes leading to some characteristics of the geopolitical division. The model departs from very simple principles of geopolitical theory and geometrical considerations, but succeeds to explain general features related to the actual process. At the same time, we will propose an evolutionary explanation to the fact that most capitals (in Eurasia) are located far from the borders or coasts and, in many cases, close to the barycenter of the respective countries.
