The protesters stood in front of the White House with the signs including ‘ Mr.President what will you do for women suffrage?’ and ‘Mr President hor long must women wait for liberty?’

President Woodrow Wilson was not responding positively to the protesters initially, but the women were persistent. The women protest was from February to November 1917.

The protest led to many women being arrested, jailed, brutally treated, and fed forcefully in prison. 

The ill-treatment towards women resulted in outrage and made the public opinion, towards the favour of Constitutional amendment for women’s suffrage, stronger.

The aftermath of this protest is the most impactful events of the suffrage movement. By the end of the 20th Century, women were given right to space outside as well as inside the home and demand for their formal political role.

World War I had powerful nations in conflict, and it brought various new technological advancements on fighting arenas. It resulted in introducing modern artillery, machine guns, and aeroplanes.

To hold the German army back, the French were throwing tear gas grenades but were unable to keep them again as Germans had the most effective dense chlorine gas at Ypres.

The gas canisters which had nastier and newer developed strains were taken up by both sides to speed up.

Amongst all gases, Mustard gas was the most effective one. It was tough to spot and could form temporary blindness.

Mustard gas could also cause blistered skin and vomiting but mostly took the lives of the people. 

World War I led to Chemical Warfare, which has been one of the most troubling methods of warfare since then.

World War I announced the birth of the League of Nations, for the world’s peace and security. It was the first international organization in the world. Members of the league are to respect territory and sovereignty of all nation-states.

Military during the war faced various medical problems such as anxiety, tremor, nightmares, and hearing-sight issues due to the explosions on the field of battle.

The symptoms started from concussion to the nervous system.

P.T.S.D was identified by the work of Charles Myers, a psychologist. According to him, symptoms seen in the military were the result of psychological experiences.

Shell Shock was renamed as the Post Traumatic Stress Disorder only in the year 1980. By then, the medical problem was accepted as a result of the intensity of modern warfare.

Those who took part and fought in the Great War were known as the Lost Generation as they never got to recover from the sufferings fully.

1. Treaty of Versailles ( June 28, 1919) 

The Treaty of Versailles ended the war between the Allied Powers and Germany on 28th June 1919.

One of the harshest clauses of this treaty was the War Guilt Clause in which Germany was blamed for the outbreak of hostilities.

It had to disarm, pay reparations of $5 million to the Allied Powers, and make territorial concessions.

The reparations led to massive unemployment and hyperinflation in the nation, and the embarrassment led to the rise of the Nazis ( National Socialists) and became a contributing factor in the outbreak of WWII.
