A boycott is a collective and organized ostracism applied in labour, economic, political, or social relations to protest practices that are regarded as unfair. The boycott was popularized by Charles Stewart Parnell during the Irish land agitation of 1880 to protest high rents and land evictions. The term boycott was coined after Irish tenants followed Parnell’s suggested code of conduct and effectively ostracized a British estate manager, Charles Cunningham Boycott.
