Between 1300 AD and 1400 AD the trend in the Americans was the increase of population; in 1300 AD there were 32 million people in the Americas, and in 1400 AD there were 39 million. So, before the European arrival, Indian populations were on the rise.
In Europe and in Asia, the trend was the decrease of the population, an event in which the deadly plague and other diseases played an important role. In 1300 AD there were 70 million people in Europe and one hundred years later, only 52 million. In Asia, in 1300 AD there were 83 million people in China, and in 1400 AD, there were 70 million.

World war 1 broke out in 1914 because a group of Serbian nationalists (The Black Hand) assassinated the duke of Austria-Hungary. Austria -Hungary threatened Serbia with a bunch of wishes that they wanted Serbia to due for them. Due to the treaty between Serbia and Russia, Serbia said no. Germany, who had a treaty with Austria-Hungary threatened to attack if Russia mobilized its army. Russia did and Germany invaded Belgium. This brought Great Britain and France into the war.
The progressive reforms were prompted by the progressives who included men and women who fought against ruthless big business and corporations, trusts and political machines and called for reforms to combat the evils of child labor, poor working conditions, health and safety, squalid living conditions, the rights of women and minority groups, unfair business practices and consumer protection.
Even if the United States had wanted to enter the war, its military force was simply not ready.
