Slavery

A slave was an individual forced to perform tasks. It could be differentiated from the free role of a servant.

Many species, such as the Ood (DW: Planet of the Ood) and Mutos, were forced into slave labour. (DW: Genesis of the Daleks)

Some races, such as the Daleks, altered individuals into becoming slaves. Example of such are the Robomen, (DW: The Dalek Invasion of Earth) Cybershades (DW: The Next Doctor) and New Humans. (DW: New Earth)

Humans have regularly been subjugated in slavery. Examples of this are their forced labour in Bedfordshire, (DW: The Dalek Invasion of Earth) the building of the New Time Lord Empire (DW: Last of the Time Lords) and forced experimentation by the Daleks. (DW: Daleks in Manhattan) Humans have often enslaved other members of their race. (DW: The Romans)
