Contemporary Africa is a very specific expanse where territories and boundaries always played major role. The shape of boundaries is one of the main problems in African countries since long time. Boundaries imposed by colonist countries often didn’t mirror the real divisions and differences on relevant territory. These days many scientists notice a huge value of boundaries and territories on African continent. One of them is Achille Mbembe - theorist of post colonialism, African issues expert and the author of some well-known political essays. According to Mbembe a boundary is not always the end, it's often just the beginning of wide-ranging consequences in behaviour of some objects of foreign affairs. Colonialism and its results are in his opinion the first factor that impacted and still does on territorial situation in Africa. The second is a regional integration that is nowadays happening in Africa. Mbembe marks out three parts of African continent and pays attention to some connections among them. In his opinion every region, every area has its use and can be domesticated even if is regarded as marginal. Africa is constantly pulling itself apart and taking on new shapes under the combined effects of demography, massive urbanisation and the economic, military and religious ambitions being pursued.
