James Otis was an influential American lawyer and political activist in the 18th century. He is best known for his strong opposition to British taxation and policies, particularly the Stamp Act of 1765. Otis argued that taxation without representation was unjust, helping to ignite the growing sentiment for independence among the American colonies. In 1761, Otis famously argued against the use of writs of assistance, which allowed British officials to search colonial homes without a warrant. His passionate speeches and writings inspired many, including future leaders like Samuel Adams and John Adams, and he is often regarded as a key figure in the early American revolutionary movement.
