In June 1919, the treaty of Versailles is concluded. 

This treaty, and the similar Treaty of St. Germain between Austria-Hungary and the Allies together help to foster some of the grievances and weaknesses which will form the causes of

World War II. 

   Germany is to be largely disarmed and the Rhineland is to be occupied by Allied forces. Considerable reparations are to be paid but the amount of the burden is not yet fixed.  The map of Europe is substantially redrawn. From the wreck of the former Austro-Hungarian Empire a whole group of new states are created. Each of these states has grievances against the others and none has a wholly homogeneous population.

   Poland too has been created and will fight successfully in 1920 to retain its independence again the Soviet Union.

Japan (still allied with Britain) gains a mandate over islands in the Pacific, including the Marshalls, Marianas and Carolines.

The Charter of the Leaque of Nations is part of the Versailles agreement but its scope is left substantially weakened by the refusal of the United States Congress to ratify it.

   On July 19, 1866, Tennessee becomes the first state to ratify the 14th Amendment.

   It granted  citizenship to “all persons born or naturalized in the United States,” which included former slaves recently freed. In addition, it forbids states from denying any person "life, liberty or property, without due process of law" or to "deny to any person within its jurisdiction the equal protection of the laws.” By directly mentioning the role of the states, the 14th Amendment greatly expanded the protection of civil rights to all Americans and is cited in more litigation than any other amendment.

   In 1925, Adolf Hitler publishes his book Mein Kampf (original title was "Four and a Half Years (of Struggle) Against Lies, Stupidity and Cowardice")

During Hitler's years in power, the book was given free to every newlywed couple and every soldier fighting at the front. By 1939 the book had sold 5.2 million copies in eleven languages. By the end of the war, about 10 million copies of the book had been sold or distributed in Germany.

   The Spanish Civil War begins, (1936–39), when the Spanish army revolted against the Republican government of Spain, supported by conservative elements within the country and led by General Francisco Franco. When an initial military coup failed to win control of the entire country, a bloody civil war ensued, fought with great ferocity on both sides. The Nationalists, as the rebels were called, received aid from Fascist Italy and Nazi Germany. The Republicans received aid from the Soviet Union, as well as from International Brigades, composed of volunteers from Europe and the United States.

2006 - Founders Noah Glass, Jack Dorsey, Even Williams, and Biz Stone — along with the rest of the team — launched their social networking service Twitter. 

Marking today as the tenth year anniversary of the social networking giant, and continues to expand by users around the world! 

We may have one oath, 

An oath that follows, but

It's not always ours.

From distant nations,

To fight as one brotherhood,

In raging conflicts.

May march by our

Will to endure the pain, but -

We are not the same.
