People who free others from captivity, oppression, slavery, or constraints.
From 'free' (verb, Old English frēon) + '-er' (Old English -ere, agent suffix forming 'one who does'). An agent noun that became more prominent during abolitionist movements.
Freers—abolitionists, freedom fighters, and those who helped enslaved people escape—literally put themselves at risk; some hid fugitives, others fought wars, and the word honored their dangerous moral choices.
