The Code contemplates the whole population as falling into three classes, the amelu, the muskinu and the ardu.
It is most difficult to characterize the muskinu exactly.
There is little trace of serfs in Babylonia, unless the muskinu be really a serf.
The service was usually discharged by slaves and serfs, but the amelu (and perhaps the muskinu) went to war.
This is awarded by the Code for corporal injuries to a muskinu or slave (paid to his master); for damages done to property, for breach of contract.
