In the year 1783, the first printed reference to Beethoven appeared in the Magazin der Musik - "Louis van Beethoven a boy of 11 years and most promising talent. He plays the piano very skilfully and with power, reads at sight very well the chief piece he plays is Das wohltempierte Klavier of Sebastian Bach, which Herr Neefe puts into his hands.
In 1783 Mozart and his wife were in Salzburg visiting his family. His father and sister were kind to Constanze, however the visit inspired one of Mozart 's great liturgical pieces, the Mass in C minor, to be written. It was premiered in Salzburg, though incomplete, with Constanze singing a solo role.
This earthquake, with an estimated magnitude of 7.0, affected a large area including most of the southern Italian peninsula and shook the whole island of Sicily. Many villages were damaged and as many as 180 almost completely destroyed, with more than 25,000 casualties. A tsunami affected the coastline on both sides of the Straits of Messina, destroying the harbor walls at Messina. The earthquake had already caused widespread death and destruction in Messina. Homes were razed to the ground, the medieval Duomo was badly damaged and most of the historic buildings were reduced to rubble.
This magnitude 6.2 event occurred during the night following the first event and struck the area just to the southwest. Most of the damage and casualties appear to have been caused by a tsunami that was set off by a major collapse of Monte Pací into the sea near Scilla shortly after the earthquake. Many of Scilla's residents, frightened by the tremors of the previous day had moved onto the open beach for the night, where they were overwhelmed by the waves. The tsunami caused severe flooding in the town, reaching as far as 200 m inland, and there were more than 1500 deaths.
This event occurred at about midday 40 km NE of the first mainshock on the 5th. Severe damage extended 15 km along the front of the Serre Mountains, leveling all the villages between Acquaro and Soriano Calabro. The earthquake is thought to have involved the rupturing of the southern segment of the Serre fault that bounds the Mesima Basin.
The final event of the sequence was of similar magnitude to the first and had an epicenter about 20 km east of the fourth, near Girifalco and Borgia in the Catanzaro Basin. The earthquake lasted for about ten seconds, and many villages were destroyed with many hundreds dead in Borgia, Girifalco, Maida, and Cortale. Landslides were common and sand volcanoes were seen, particularly on the banks of the Amato river. This earthquake has not been tied to a particular fault, but a recent re-evaluation of the intensity data indicates that the isoseismal areas are elongated NE–SW, suggesting faulting of similar trend to that observed for the other earthquakes in the sequence.
Constanze gave birth to a baby boy named Raimund Leopold, but the Mozarts took a trip to Salzburg to see Leopold, leaving Raimund Leopold in Vienna as a young infant. Their son died when they were away, so the Mozarts left for Vienna.
Before returning to private life in June 1783, Washington called for a strong union. Though he was concerned that he might be criticized for meddling in civil matters, he sent a circular letter to all the states maintaining that the Articles of Confederation was no more than "a rope of sand" linking the states. He believed the nation was on the verge of "anarchy and confusion", was vulnerable to foreign intervention and that a national constitution would unify the states under a strong central government.
Washington advised Congress in August 1783 to keep a standing army, create a "national militia" of separate state units, and establish a navy and a national military academy. He circulated his "Farewell" orders that discharged his troops, whom he called "one patriotic band of brothers". Before his return to Mount Vernon, he oversaw the evacuation of British forces in New York and was greeted by parades and celebrations, where he announced that Knox had been promoted commander-in-chief.
Washington resigned as commander-in-chief once the Treaty of Paris was signed, and he planned to retire to Mount Vernon. The treaty was ratified in April 1783, and Hamilton's Congressional committee adapted the army for peacetime. Washington gave the Army's perspective to the Committee in his Sentiments on a Peace Establishment. The Treaty was signed on September 3, 1783, and Great Britain officially recognized the independence of the United States. Washington then disbanded his army, giving an eloquent farewell address to his soldiers on November 2.
The 1783 Calabrian earthquakes were a sequence of five strong earthquakes that hit the region of Calabria in southern Italy (then part of the Kingdom of Naples), the first two of which produced significant tsunamis. The epicenter of the first earthquake occurred in the plain of Palmi. The earthquakes occurred over a period of nearly two months, all with estimated magnitudes of 5.9 or greater. Estimates of the total number of deaths lie in the range 32,000 to 50,000.
After leading the Continental Army for 8½ years, Washington bade farewell to his officers at Fraunces Tavern in December 1783, and resigned his commission days later, refuting Loyalist predictions that he would not relinquish his military command.
