March 15– The day after his return to Paris from a nine-year mission, French explorer and scholar Anquetil Du Perron presents a complete copy of the Zoroastrian sacred text, the Zend Avesta, to the Bibliothèque Royale in Paris, along with several other traditional texts.[4] In 1771, he publishes the first European translation of the Zend Avesta.
March 20– After the British victory in the French and Indian War, the first post-war British expedition to explore the newly acquired territories east of the Mississippi River comes under attack by Tunica warriors. The 340 British Army men, under the command of Major Arthur Loftus, were at a spot south of Natchez, Mississippi and were forced to flee in their boats back toward the port of New Orleans while under fire from an unknown number of Tunicas firing from both banks.[6]
March 27– The prince-electors, a group of nine German princes who select the next leader of the Holy Roman Empire, vote for the last time as the health of the Emperor Francis I declines. The electors (including Britain's King George III, who also rules as Elector of Hanover) approve Francis's son, Prince Joseph of Austria as King of the Romans. Upon the death of Francis in 1765, Prince Joseph becomes the Holy Roman Emperor Joseph II.
April 21– Residents of French Louisiana are informed for the first time that they will come under Spanish rule as the result of a secret agreement of November 13, 1762 whereby France has ceded all of its North American territory west of the Mississippi River.[9] The Spanish, however, do not take possession until August 17, 1769.
April 27– Eight-year-old child prodigy Wolfgang Amadeus Mozart performs a private concert before King George III and Queen Charlotte in Great Britain, and has an encore on May 19.[10]
May 3–Baden, one of the member states of the Confederation of Switzerland, declares a policy of remaining neutral in future conflicts, a model that is soon followed by other members of the Confederation and which eventually becomes the basis for Swiss neutrality from 1815 onward.[11]
June 21– The English-language Quebec Gazette is established in Quebec City, Canada (the oldest surviving newspaper in North America).
July 6– The last British troops depart Havana, Cuba, two years after having captured it from Spain during the Seven Years' War. The removal of troops follows the treaty between the two Kingdoms, with Spain ceding West Florida to Great Britain in return for the Havana withdrawal.[12]
July 8– The Niagara Conference begins at the invitation of Sir William Johnson, the British Superintendent of Indian Affairs for the northern district, who hosts "one of the largest conventions of red men ever held on the continent" to negotiate the end of the hostilities from the French and Indian War. Reportedly, 2,000 representatives of the North American tribes meet at upstate New York coming from distances ranging "From Dakota to Hudson's Bay, and from Maine to Kentucky." [13]
July 11– Conditional repatriation of the Acadians in Canada, French colonists who took up arms against the British during the war, is approved by order of King George III on advice of the Privy Council. The Council offers settlement to any Acadians willing to take an oath of allegiance to the British Crown and that those living in New Brunswick are to "be allowed to settle in Nova Scotia, but that they should be dispersed in small numbers in various localities." [14]
July 26– In what is described 250 years later as "The first documented United States school shooting",[16] a group of four Delaware Indians invade a schoolhouse near what is now Greencastle, Pennsylvania and kill ten schoolchildren and their teacher, Enoch Brown.[17] The massacre happens in the course of Pontiac's War, as retaliation against white settlement of Indian lands in central Pennsylvania. One student, Archie McCullough, manages to escape the carnage; a memorial is erected 120 years later on August 4, 1884.[18]
July 31– Johnson arrives at the Niagara River site to meet with the representatives of the Indian nations.[19]
