slaveera
Slave era is a descriptive term used to refer to periods in which slavery was a legally recognized and economically important institution. Because slavery took different forms in different places and times, there is no single universal “slave era.” The term is commonly used in historical writing to denote a period in which enslaved people formed a significant part of the labor force and social hierarchy, and where laws defined their status and rights in relation to free persons.
Forms and institutions vary by region. In ancient Mesopotamia, Egypt, Greece, and Rome, slavery was widespread
Time span and geography also vary. The concept can extend from antiquity through the transatlantic slave trade
