What happened 1784 AD

Washington was longing to return home after spending just 10 days at Mount Vernon out of ​8 1⁄2 years of war. He arrived on Christmas Eve, delighted to be "free of the bustle of a camp and the busy scenes of public life". He was a celebrity and was fêted during a visit to his mother at Fredericksburg in February 1784, and he received a constant stream of visitors wishing to pay their respects to him at Mount Vernon.

On completion of his studies at Brienne in 1784, Napoleon was admitted to the École Militaire in Paris.

Mozart met Joseph Haydn in Vienna around 1784, and the two composers became friends. When Haydn visited Vienna, they sometimes played together in an impromptu string quartet. Mozart's six quartets dedicated to Haydn (K. 387, K. 421, K. 428, K. 458, K. 464, and K. 465) date from the period 1782 to 1785.

Constanze delivered their second child, Karl Thomas, on September 21. Karl Thomas will live to the ripe old age of 74, unlike his brother Raimund. His parents moved house very early in his childhood, again. This time it was to the Domgasse which was much more salubrious. And salubriousness brought expense with it, with the flat costing a staggering 450 gilder a year for the Mozarts.

The eastern portion of the Bank of America franchise can be traced to 1784 when Massachusetts Bank was chartered—the first iteration of FleetBoston, which Bank of America acquired in 2004.

On 14 December 1784, Mozart became a Freemason, admitted to the lodge Zur Wohltätigkeit ("Beneficence"). Freemasonry played an essential role in the remainder of Mozart's life: he attended meetings, a number of his friends were Masons, and on various occasions, he composed Masonic music, e.g. the Maurerische Trauermusik.
