Emperor Charlemagne (742-814) ruled Western Europe during the middle ages for more over than 40 years. After his decease, his domains had to face the ineptitude of his new rulers -Charlemagne heir, who buy the year 800 did nothing but dissolve the Empire.

If the border with Laos had been closed and North Vietnam had not been able to operate in the country, the communist side would not have been able to stock up on resources, men, ammunition, weapons, food and medicine through the HoChi Minh Trail.
Therefore, the forces of the North that were fighting in South Vietnam would have been out of supply, and their defeat would have been imminent.
The order of events from oldest to newest is: 5, 3, 1, 2, 6, 4.
<h3>How to organize the events chronologically?</h3>
To organize the events chronologically we must look at their date of occurrence. In this case we have date with the following AD and BC. This acronym means:
- AD - After Christ
- BC - Before Christ
On the other hand, it should be remembered that in the years before Christ they are counted in descending order, that is to say that a very old event has a high number, for example 1000BC, while a more recent event has a lower number, for example 100BC .
According to the above, the correct order is:
- 5) Zhou Dynasty in China founded, 1000 BC
- 3) Decline of Olmec culture, 400 BC
- 1) Rise of the Roman Empire, 40BC
- 2) Destruction of Jerusalem by the Romans, AD 70
- 6) Fall of Han Dynasty in China, AD 200
- 4) Early Middle Ages begin in Europe, AD 400
