WHERE DOES THE WORD BOYCOTTER COME FROM?

An Irish captain, James Boycott, Lord Irme's steward, had made himself odious by his exactions. To take revenge, the peasants put him in quarantine; they refused to look after his cattle, to plough his fields and even to sell him food. Reduced to starving, the captain had to leave the country.

Some time later, the leaders of the Irish party, Parnell and Michael Davitt, were having lunch at the house of a neighbouring priest, John O'Malley, and were discussing this curious public vindictiveness.
They said, a word should be found to designate these methods of defence.
— But it is already found, replied the priest, one could say boycotting.
— Perfect! Adopted! cried Parnell and Davitt.
