In the 1700s, James Watt caused a revolution in transportation<em> by improving steam engine technology.</em>
He was a Scottish inventor and mechanical engineer. He made improvements on Thomas Newcomen's steam engine that was patented in 1698 and widely in use at the time of Watt's birth ( 1736).
It all started when Watt was given a model Newcomen engine to repair. He realized it was very inefficient and he began to find ways to improve its performance. He designed a separating condensing chamber for the engine to avoid huge losses of steam. He patented his improvements in 1769.
A unit of measurement of electrical and mechanical power -<em> the watt</em> - is named in his honor.

The first world war placed an unbearable strain on Russia's weak government and economy, resulting in mass shortages and hunger. In the meantime, the mismanagement and failures of the war turned the people and soldiers against the Tsar whose decision to take personal command of the army seemed to make him personally responsible for the defeats. In March 1917, the Tsar first lost control of the streets, then the soldiers, and finally of the Duma, resulting in his forced abdication on March 15th, 1917.
