The issue of state failure within the international system has been a perplexing phenomenon in our increasingly mobile and modern society. The question of why some states succeed in developing into strong states within the international environment and why some fail is a question often overlooked. The research will show how these three key factors: outdated state infrastructure, lack of economic development, and external intervention contribute to the occurrence of this phenomenon. Analyzing these key factors will highlight how state failure occurs within a case study. The chosen state for the focus will be the Democratic Republic of the Congo (DRC). By focusing on this case I plan to cross-reference factors that have been commonly used to gauge state failure. This will show that external factors, as well as internal factors can cause detrimental obstacles in state development. My research will show that the three key factors are the reason why the DRC became a failed state.
