Italy≠Roman Empire, Rome was a city that is now the capital of Italy. Italy it self only came around at a similar time to Germany causing the fall of the HRE.
Italian and German unifications did not cause the fall of the HRE, because the HRE didn't exist anymore at this moment. It was dissolved in 1806. Although a very similar thing, the German Confederation, existed from 1815 to 1866.
Canada didn't become a country in 1867. It became a dominion, which was still part of the British Empire. While it was autonomous, the UK still controlled its foreign policy. Canada really became independent only with the Statute of Westminster 1931, or even arguably in 1982 when it gained the right to modify its constitution without the UK's consent.
Adams and Jefferson died in the 50th anniversary if the Declaration of Independence, written mainly by Jefferson. Monroe died on the 55th anniversary. Thus the 2nd, 3rd and 5th Presidents all died on the Fourth of July. Hannibal Hamlin, Lincoln's Vice President who was replaced 41 days before Lincoln was shot would have been the 17th President and died July 4 on the 115th anniversary. Reconstruction would have been radically different and there would have been no precedent for a President getting impeached when they decided to impeach Clinton for lying about extramarital sex behind his wife's back.
Other trivia: Maine's other 2 shots at having a President from the state were James G. Blaine and Edmund Muskie. Blaine, perpetually in scandals, was snubbed at the Republican National Convention of 1876 after 7 rounds of ballots to get a majority nominee ended in backroom deals. He had long been the front runner. The disputed Presidential election was decided by Congress with another backroom deal that allowed the Republican candidate to be President if troops were removed from the South and Civil War Reconstruction brought to an end. This reversed the empowerment of blacks in the South, many of whom political office, and disenfranchised them for 80 years. Failing again in 1880, he was nominated in 1884, losing the Presidency by 1,000 votes in winner Grover Cleveland's home state of New York. In 1888 Cleveland lost his home state and thus reelection. He subsequently won the 1892 election, the only person to be President in nonconsecutive terms.
The elections of 1876 and 1888 were the only times people became President despite not being chosen by the majority of the people until George W. Bush and Donald Trump.
That was what I knew off the top of my head. Googling, I also see Eva Gabor died on July 4th, 1995. She was famous for being on the hokey Hollywood stylized version of podunk known as Green Acres. Its outdoor scenes were obviously filmed on a stage with painted trees in the background. Mellow painter of happy trees and Mr. Rogers-esque televised painting instructor Bob Ross died the same day. Ross was also name of the maker of the flag flown by the first President while rebelling to create the country. With that ominous note (you reading all this, Alex Jones???), I end my encyclopedia of July 4th death.
the hre practiclly wasnt a unified state since like the 1200s hundreds, but before then, it was very much a nation, very centralized or at least as much as a medieval state could be
The HRE was a country, but it was never a nation. Also, it has nothing to do with Germany. The concept of Germany wasn't even invented until the early 19th century.
That is the same as to say that the United States existed as it is only since 1959 (when Hawaii was added). The Federal Republic of Germany has existed under that name and under that constitution since 1949. The German Democratic Republic (East) dissolved in 1990 and accepted to be part of the Federal Republic. Look at Wikipedia's last paragraph in the introduction of German reunification: "The post-1990 united Germany is not a successor state, but an enlarged continuation of the former West Germany."
So on 4 July 1826 the States lost both the man who practically wrote all of the Declaration of Independence and an egoistic man whose clothes were stolen when he went for a swim in the Potomac?
About the John Adams story: he sent a farm lad to the White House to get him something to wear.
I don't think that's how you should count it, given that modern germany (the federal republic of germany) only has existed since 1949, and unified germany since 1980; while France has existed since at least the 11th century
I mean, it's a bit of a pointless fact that might only interest those with very little historical knowledge. Almost all nations as we know them today emerged relatively recently (within the last 200 years or so). One thing is for sure though: German history goes back way further than US history.
Germany as a concept appeared at the beginning of the 19th century. German Nationalism tried to retcon the history to make it appear longer, but it really is an artefact that grow after Napoleon and the American Revolution. Of course, as you said, Nationalism is a relativly young phenomenon in both countries, just that the US tends to ignore the Native history, while Germany tries to appropriate it.
If an American citizen was born in 1825 and lived until the end of 1919 he would have shared part of his lifespan with every president between John Adams and Ronald Reagan, except for Jimmy Carter who wasn't born until 1924.
Curie was born Marja Sklodowska but changed her first name to Marie when she moved to France and her surname to Curie when she married Pierre Curie, a prominent scientist at the Sorbonne.
It wasn't really about the world. Neither did Germany 'attempt' much more than the other major powers. Somehow, WWII rubs off retrospectively on WWI in the minds of many people.
Germany really didn't want to get into WWI. Yes, they did antagonize the British by building up the navy, but they did this in response to the threat of Royal Navy blockade. The Germans only really got involved in WWI because Serbia refused to hand over the Black Hand members to Austria-Hungary. A-H did not like that and declared war. Serbia appealed to Russia for help. Russia declared war on A-H. A-H appealed to their ally, Germany, and Germany had to declare war on Russia. France and the UK, both allies of Russia, had to declare war on Germany. Italy, who had territorial disputes with A-H declared war on A-H (the failure of the UK and France to give Italy the territory they wanted is what caused Italy to join the Axis in WWII). The Ottoman Empire declared war on Russia. The Ottoman Empire had been on their deathbed for a century and A-H was not much better, so Germany, with the best military, provided the leadership and were blamed by a vengeful France for the start of the War.
Actually, the HRE was destroyed by Napoleon in around 1806. The Austrian, then the Austro-Hungarian Empire took part of it (the Habsburgs remaining Emperors). Prussia unified Germany in 1871, taking most of it's former territory. Italy was unified after a series of wars between the 1860 and 1870 but most of Italy had been independent of the HRE for centuries. Modern Germany only really came into being in 1990 after reunification. The USA as we know it today only came about when Hawaii joined. Therefore, Italy is older and Germany is younger.
