Fifty years after independence, African countries are still in a worse economic situation than the rest of the world. The aim of this paper is to analyze the available scientific papers and literature to assess whether state borders are an obstacle to the economic development of Africa. The borders drawn by the colonial rulers are the cause of numerous war conflicts. Numerous peoples in Africa lost their states and kingdoms with the arrival of the colonizers. An important segment of a nation's cultural identity is the border. Borders divided peoples between two or more states and made their position in the newly created states much more difficult. African mineral wealth is a problem in border areas, where war conflicts have often occurred. The International Court of Justice has resolved several border disputes in the last fifty years, but unfortunately there are still many border disputes. There are many international and regional economic organizations in Africa that are trying to stimulate economic growth and development in Africa. The content of the diploma thesis is a good basis for geography teachers to prepare classes related to state borders.
