slavesoldier
Slavesoldier, or slave soldier, is a historical term for a person held as a slave who is trained and employed as part of a military force. In various empires, slave soldiers were used to staff elite units or entire armies, often as a way to create a loyal fighting force insulated from local power structures. Recruitment typically involved captives taken in war, purchase of slaves, or other forms of captivity. Recruits were commonly converted to the dominant religion and trained from a young age in martial skills, discipline, and loyalty to their masters or rulers. The legal and social status of slave soldiers varied widely, from tightly controlled infantry or cavalry to individuals who could attain high rank or even political influence within a state.
Notable examples include the Mamluks of Egypt and Syria, whose slave soldiers eventually founded a ruling dynasty
From the 18th to 19th centuries, many states moved away from slave-based forces toward professional standing
