James Otis (born Feb. 5, 1725, West Barnstable, Mass. [U.S.]—died May 23, 1783, Andover, Mass.) was an American political activist during the period leading up to the American Revolution. He helped formulate the colonists’ grievances against the British government in the 1760s.
Son of the elder James Otis, who was already prominent in Massachusetts politics, the younger Otis graduated from Harvard College in 1743 and was admitted to the bar in 1748. He moved his law practice from Plymouth to Boston in 1750. His reputation was built mainly upon his famous challenge in 1761 to the British-imposed writs of assistance—general search warrants designed to enforce more strictly the trade and navigation laws in North America. These search warrants authorized customhouse officers to search any house for smuggled goods; neither the house nor the goods had to be specifically mentioned in the writs. Arguing before the Superior Court in Boston, Otis raised the doctrine of natural law underlying the rights of citizens and argued that such writs, even if authorized by Parliament, were null and void. In harking back to fundamental English constitutional law, Otis offered the colonists a basic doctrine upon which their publicists could draw for decades to come. At this time he also reportedly coined the oft-quoted phrase “Taxation without representation is tyranny.”
Otis was elected in May 1761 to the General Court (provincial legislature) of Massachusetts and was reelected nearly every year thereafter during his active life. In 1766 he was chosen speaker of the house, though this choice was negated by the royal governor of the province.
In September 1762 Otis published A Vindication of the Conduct of the House of Representatives of the Province of Massachusetts Bay in defense of that body’s rebuke of the governor for asking the assembly to pay for ships not authorized by them—though sent to protect New England fisheries against French privateers. Otis also wrote various state papers addressed to the colonies to enlist them in the common cause, and he also sent such papers to the government in England to uphold the rights or set forth the grievances of the colonists. His influence at home in controlling and directing the movement of events toward freedom was universally felt and acknowledged, and few Americans were so frequently quoted, denounced, or applauded in Parliament and the British press before 1769. In 1765 he was a delegate to the Stamp Act Congress in New York City, and there he was a conspicuous figure, serving on the committee that prepared the address sent to the House of Commons.
Already prone to fits of insanity, Otis was struck on the head during an altercation with a crown officer in 1769 and was rendered harmlessly insane, with only occasional lucid intervals, until his death. He died in 1783 after being struck by lightning.
