The article examines the reasons for the increasing terrorist activity in Burkina Faso after the revolution in 2014. For decades, the Sahel has been one of the most unstable regions in Africa and the Afrasian zone of instability. However, in the 2010s the Sahel has experienced a dramatic increase in terrorist activity: by 2015, the number of terrorist attacks there increased more than seven times compared to 2010. At the same time, the dynamics of terrorist activity in Burkina Faso had its specific characteristics compared to the rest of the Sahel. The growth of terrorism in this country was largely a consequence of the overthrow of the B. Compaoré regime. The new authorities were unable to maintain security at the same level. This can be explained, on the one hand, by the stable agreements that had been settled between Compaoré and terrorist structures. His resignation destroyed all the informal ties and agreements that the regime had established with regional jihadist organizations, freeing their hands to infiltrate Burkina Faso quickly and easily. On the other hand, the dissolution of the Regiment of Presidential Security (precisely the structure largely responsible for the fight against terrorism) after the failed military coup attempt of September 2015 played an important role. The new leadership stripped the country of the protection they had against jihadist organizations poised to infiltrate across the border into Burkina Faso. As a result, after 2015, a very safe country in terms of terrorism faced an unprecedented increase in terrorist activity.
