Jefferson used the Enlightenment ideals in the Declaration of Independence such a natural right, birth rights, all men are created equal.
Explanation:
In the Declaration of Independence, Jefferson operated the idea of "unfair rights" in similar to the idea of natural rights, which comes from Locke. According to him (Locke) there are many rights with which people are born and these rights cannot be taken away by the government.
Similar to Locke, Jefferson stated that all men (people) are created with equal rights and they should be treated equally. Thus, this situation is helpful for the peaceful growth of country and citizens.
The main idea of the Trail of Tears in 1838 and 1839 was to force the Cherokee nation to give up its land in the Mississippi river and migrate to present Oklahoma, as part of Andrew Jackson's Indian removal policy, this way the white settlers could grow cotton on the Indians land. It is important to learn about it to enforce the laws and protect the rest of the indigenous civilization in modern days
The use of poison gas in World War I was a major military innovation. The gases ranged from disabling chemicals, such as tear gas and the severe mustard gas, to lethal agents like phosgene and chlorine. This chemical warfare was a major component of the first global war and first total war of the 20th century. The killing capacity of gas was limited — only 4% of combat deaths were due to gas — however, the proportion of non-fatal casualties was high, and gas remained one of the soldiers' greatest fears
Poison gas was indiscriminate and could be used on the trenches even when no attack was going on. Whereas the machine gun killed more soldiers overall during the war, death was frequently instant or not drawn out and soldiers could find some shelter in bomb/shell craters from gunfire. A poison gas attack meant soldiers having to put on crude gas masks and if these were unsuccessful, an attack could leave a victim in agony for days and weeks before he finally succumbed to his injuries.
By the time the war ended, the main user of poison gas was Germany, followed by France and then Britain. Though poison gas was a terrifying weapon, its actual impact, rather like the tank, is open to debate. The number of fatalities was relatively few - even if the terror impact did not diminish for the duration of the war.
PHEW!!
