The word #boycott originates from Captain Charles Boycott, an English land agent in Ireland of 1880.
He became infamous when he attempted to evict tenants after they demanded greater rent reductions due to poor harvests.
The Irish Land League organized a campaign of social and economic ostracism: workers refused to labor for him and businesses stopped trading with him.
The collective action was so effective, his name became synonymous with the tactic of organized refusal.
