They uphold morals and ideals, and The entire nation has rights and obligations are two important characteristics about the Mughal Empire.

What was India called during the Mughal period?

The Mughal Empire referred to its territory as "Hindustan." The nation was never referred to as being "Mughal" in the traditional sense. "Hindustan" expanded along with the empire. In addition, Baburnama and Ain-i-Akbari use the term "Hindustan" to refer to the entire Indian subcontinent.

Even though Turkish was the Mughals' native dialect, they utilized Persian so frequently in daily life that they became fluent in it and created some of the best Persian literature, including works of poetry by Babur, Humayun, DaraShukoh, and Zaib-un-Nisha, among others.

Thus, They uphold morals and ideals, and The entire nation has rights and obligations.

The trail of tears impacted the cherokes. The trail of tears is a path were the cherokes were forced to move out of thier homes. Many children and elderly was lost and died on that path and many cried about thier deaths.

The trail of tears affected native populations at the time heavily due to the fact that thousands died decrease the population by a numerous amount. Native populations in the future were affected because it caused the native to have an even smaller population because not only did many die it was children that died and so the new generation was gone and its hard enough to have another kid at an old age never the less with no technology like what we have now.

Read the following selection introducing the Popsicle.

Frozen treats have existed for centuries. But none of them had a stick handle until 1905. That's the year when Frank Epperson, an 11-year-old boy from California, mixed a fruit-flavored soda powder with water in a glass. He stirred it with a wooden stick and took it out onto the porch. He drank only a few sips before he set it down and forgot it. The weather turned cold, and the next morning, he discovered his flavored drink was frozen solid with the stick in it. He pulled the stick out of the glass and licked the ice attached to it. Yum!

Answers

Answer: Umm i got this from an an article and made it shorter

Explanation:

After the World War I, with millions washed away, people thought it was the end, but the break of World War II was even more worst than World War I. World War II or also known as the Second World War was fought between 1939 – 1945 in the Europe and Asia.  

It was the worst of wars where more than 38 million people died and the most destructive war in the history of mankind. More than 50 nations took part in the war and it did change the world forever.  

After the World War I, though the peace treaty was signed, this was the actual cause for another war. Germany was totally devastated from the war and it was then the Nazi Leader Hitler who took over and started his rule. It was the conquering of Europe by Hitler that eventually began the World War II from Europe. His invasion to Poland was the reason. Germany tried to conquer Britain but failed as they could not beat the Britain Royal Air force.

This was the largest armed battle in the history with the usage of deadly weapons, warplanes, battleships and first usage of nuclear bombs which took place. There was killing of innocent people in massive scale. By 1939, Germans troops invaded Poland and by 1941 the US also joined the war thereby taking the leadership too. By 1945, Germany surrendered thereby ending the war in Europe.

However the war in the Pacific did not end, until the US dropped two atomic bombs in Japan which was the most devastating action in history and by 1945 Japan also surrendered.

The after effects of this World War II is still being suffered by the people of Japan, even after decades has passed by. The World War II was one among the most destructive wars in the history of the world.

World War 1:
In WW1 Germany, Hungary, Bulgaria, Austria and the Ottoman Empire (these were the central powers) fought agains Russia, Italy, France, Great Britain, Japan, Romania and the United States (these were the allied Powers). This war is also known as the Great War which started in 1914 after the assassination of Archduke Franz Ferdinand. On July 28, 1914 Austria-Hungary declares war on Serbia which started the WW1. The four main causes were imperialism, alliances, nationalism and militarism. This war lasted 4 years where 21 million people died and 21 million where injured. It ended on 11 November 1918 and on June 28, 1919 Germany and the Allied signed the Treaty of Versailles, which formally ended WW1.

World War 2:
In WW2 Germany, Italy and Japan (Axis Power) fought against France Great Britain, the Soviet union, the United States and China (Allied Powers). Hitler attacked Poland on September 1, 1939 (this was an attack that he planned for months). France and Great Britain had guaranteed military support if Poland was attacked by Germany so two days later after Hitler’s strike they declared war. The main causes of it were impact of the Treaty of Versailles following WWI, the worldwide economic depression and the failure of peace efforts. During WW2 Nazy Germany killed around 6 million European Jews (Hitler’s discrimination) - this event is knows as the Holocaust. On 2 September 1945 the USS Missouri in Tokyo Bay, Japan formally surrenders to the Allies, bringing an end to World War II.

What were the major empires in between the 11th-16th centuries?

Answers

Explanation:

The development of such major Sudanic kingdoms and empires as Ghana, Mali, Songhai, the Hausa states, and Kanem-Bornu along the southern fringes of the Sahara had a number of important consequences for the history of western Africa as a whole

The precise term Sacrum Romanum Imperium dates only from 1254, though the term Holy Empire reaches back to 1157, and the term Roman Empire was used from 1034 to denote the lands under Conrad II’s rule. The term “Roman emperor” is older, dating from Otto II (died 983). This title, however, was not used by Otto II’s predecessors, from Charlemagne (or Charles I) to Otto I, who simply employed the phrase imperator augustus (“august emperor”) without any territorial adjunct. The first title that Charlemagne is known to have used, immediately after his coronation in 800, is “Charles, most serene Augustus, crowned by God, great and pacific emperor, governing the Roman empire.” This clumsy formula, however, was soon discarded.

Holy Roman Empire
Holy Roman Empire
Imperial Crown of the Holy Roman Empire, 10th century; in the treasury of Hofburg palace, Vienna.
Erich Lessing/Magnum
These questions about terms reveal some of the problems involved in the nature and early history of the empire. It can be regarded as a political institution, or approached from the point of view of political theory, or treated in the context of the history of Christendom as the secular counterpart of a world religion. The history of the empire is also not to be confused or identified with the history of its constituent kingdoms, Germany and Italy, though clearly they are interrelated. The constituent territories retained their identity; the emperors, in addition to the imperial crown, also wore the crowns of their kingdoms. Finally, whereas none of the earlier emperors from Otto I had assumed the imperial title until actually crowned by the pope in Rome, after Charles V none was emperor in this sense, though all laid claim to the imperial dignity as if they had been duly crowned as well as elected. Despite these anomalies and others, the empire, at least in the Middle Ages, was by common assent, along with the papacy, the most important institution of western Europe.


Theologians, lawyers, popes, ecclesiastics, rulers, rebels like Arnold of Brescia and Cola di Rienzo, literary figures like Dante and Petrarch, and the practical men, members of the high nobility, on whom the emperors relied for support, all saw the empire in a different light and had their own ideas of its origin, function, and justification. Among these heterogeneous and often incompatible views, three may be said to predominate: (1) the papal theory, according to which the empire was the secular arm of the church, set up by the papacy for its own purposes and therefore answerable to the pope and, in the last resort, to be disposed of by him; (2) the imperial, or Frankish, theory, which placed greater emphasis on conquest and hegemony as the source of the emperor’s power and authority and according to which he was responsible directly to God; and (3) the popular, or Roman, theory (the “people” at this stage being synonymous with the nobility and in this instance with the Roman nobility), according to which the empire, following the tradition of Roman law, was a delegation of powers by the Roman people. Of the three theories the last was the least important; it was evidently directed against the pope, whose constitutive role it implicitly denied, but it was also a specifically Italian reaction against the predominance in practice of Frankish and German elements.

It is also important to distinguish between the universalist and localist conceptions of the empire, which have been the source of considerable controversy among historians. According to the former, the empire was a universal monarchy, a “commonwealth of the whole world, whose sublime unity transcended every minor distinction”; and the emperor “was entitled to the obedience of Christendom.” According to the latter, the emperor had no ambition for universal dominion; his policy was limited in the same way as that of every other ruler, and when he made more far-reaching claims his object was normally to ward off the attacks either of the pope or of the Byzantine emperor. According to this view, also, the origin of the empire is to be explained by specific local circumstances rather than by far-flung theories.
