I'm confused about these terms, to keep it simple I've heard of people refer to khagantes and the system of Aghas in Kurdistan and sultanates as a kind of feudalism of the East with a pretty close analog of fiefdoms.
I know feudalism, even in the west, was a pretty vague term and has come to servitude to a well armed landlord with limited state powers.
The definition of Feudalism on Wikipedia is,
Feudalism was a combination of legal and military customs in medieval Europe that flourished between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships derived from the holding of land in exchange for service or labour.
Is Feudalism specific to the west, or can it be applied to the Khagantes, Aghas, and Sultanates?
