The Treaty of Versailles, signed in 1919, was the most significant peace treaty that formally ended the state of war between Germany and the Allied Powers. It imposed heavy reparations, territorial losses, and military restrictions on Germany, which had profound long-term geopolitical consequences and is often cited as a contributing factor to the rise of tensions leading to the Second World War.

In June 1919, British aviators John Alcock and Arthur Whitten Brown completed the first non-stop transatlantic flight. They flew a modified Vickers Vimy bomber from St. John's, Newfoundland, to Clifden, Ireland, covering approximately 3,116 kilometers in about 16 hours, marking a major milestone in aviation history.

The Treaty of Versailles, signed in 1919, was the most important of the peace treaties that brought World War I to an end. It officially ended the state of war between Germany and the Allied Powers, focusing primarily on the geopolitical restructuring of Europe, imposing territorial losses, and setting reparations for the defeated German Empire.

World War I began in July 1914, triggered by the assassination of Archduke Franz Ferdinand of Austria-Hungary in Sarajevo.

All three pairings are historically accurate. Richard Arkwright developed the water frame for spinning.

Richard Trevithick, a British inventor and mining engineer, successfully built the first full-scale working steam locomotive in 1804. His invention marked a significant milestone in the history of transportation and the Industrial Revolution. While others contributed to steam engine technology, Trevithick's application of high-pressure steam to rail transport laid the foundation for the development of modern railway systems worldwide.
