The Stamp Act of 1765 sparked the first great imperial crisis. This was imposed to cover part of the cost of keeping British troops in America. This act put a tax stamp on all printed items such as court documents, contracts, newspapers, playing cards and more. Many Americans opposed of this act, but it was still passed. Then, in New York City in October of 1765, nine assemblies sent delegates to the Stamp Act Congress. This protested the loss of American rights and liberties, and it challenged the constitutionality of the Stamp Act of 1765 and Sugar Act of 1764. The humbly petitioned for repeal of the Stamp Act and Americans organized a boycott of British goods.
