What are the reasons for the decline of slavery and emergence of Feudal mode of production?
1. Improvement of productive forces during the slavery; changed the social and technical relation of production and geared to the decline of slave mode of production and the rise of feudalism.
2. Existence of class struggle in slavery. The series of slaves uprising against the masters at the end of the day led to collapse of slave mode of production and hence emergence of feudalism.
3. The Failure of the productive forces to correspond with social and technical relational production (relation of production). According to Karl Marx (1818-1883) pointed out that if productive forces and social and technical relation of production in a certain mode of production are not going hand in hand with the existing mode of production then such mode of production will collapse and pave a way to another mode of production.
4. Slaves lacked interest in labour; they frequently destroyed the equipment of production owned by slave masters hence slavery collapsed.
5. The cruel exploitation of slaves and ruthlessness and oppression done by the save masters to slaves led the slaves to revolt against the slave masters hence slaves became free from being controlled by the slave masters this led to the collapse of slavery(slave mode of production).
6. The Slave owners (slave maters) with vast number of slaves were not interested in including the tools of production; they continued to use the old productive forces which automatically led to the collapse of slave mode of production.
7. The constant military campaigns led to the number of slaves to drop down and the prices to get slaves increased this led slave masters to fail to continue with this mode of production (slavery).
