Events January–March January 23 – Prince Joseph of Austria marries Princess Maria Josepha of Bavaria in Vienna. January 29 – One week before his death, Mir Jafar, who had been enthroned as the Nawab of Bengal and ruler of the Bengali people with the support and protection of the British East India Company, abdicates in favor of his 18-year-old son, Najmuddin Ali Khan. February 8 – Frederick the Great, the King of Prussia, issues a decree abolishing the historic punishments against unmarried women in Germany for "sex crimes", particularly the Hurenstrafen (literally "whore shaming") practices of public humiliation. Isaac Barré, a member of the British House of Commons for Wycombe and a veteran of the French and Indian War in the British American colonies, coins the term "Sons of Liberty" in a rebuttal to Charles Townshend's derisive description of the American colonists during the introduction of the proposed Stamp Act. MP Barré notes that "They fled from your tyranny to a then uncultivated and unhospitable country... And yet, actuated by the principles of true English liberty, they met all these hardships with pleasure, compared with those they suffered in their own country, from the hands of those who should have been their friends." American colonists adopt the term for their own organization after reading the accounts of Barré's speech. February 14 – Spain's five-member "special junta", appointed by Prime Minister Jerónimo Grimaldi, delivers its report regarding "ways to address the backwardness of Spain's commerce with its colonies and with foreign nations". The report provides detailed orders to be delivered to José de Gálvez, the visitador general in charge of New Spain. March 9 – After a public campaign by the writer Voltaire, judges in Paris posthumously exonerate Jean Calas of murdering his son. Calas had been tortured and executed in 1762 on the charge, though his son may have committed suicide. March 22 – Royal assent is given to the Duties in American Colonies Act 1765, historically referred to as the Stamp Act, imposing the first direct tax levied from Great Britain on the thirteen American colonies, effective November 1. The revenue measure (which requires the purchase of a stamp to be affixed for validation of all legal documents, but also to licensed newspapers and even playing cards and dice) is made to help defray the costs for British military operations in North America, including the French and Indian War.
