It was written for the 1913 Paris season of Sergei Diaghilev’s Ballets Russes company; the original choreography was by Vaslav Nijinsky, with stage designs and costumes by Nicholas Roerich. When first performed, at the Théâtre des Champs-Élysées on 29 May 1913, the avant-garde nature of the music and choreography caused a sensation and a near-riot in the audience. Although designed as a work for the stage, with specific passages accompanying characters and action, the music achieved equal if not greater recognition as a concert piece and is widely considered to be one of the most influential musical works of the 20th century.

1919 – Einstein’s theory of general relativity is tested by Arthur Eddington and Andrew Claude de la Cherois Crommelin.

General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton’s law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations.

It was predominantly white and had many Jewish members, thus marking the beginnings of the coalition, which along with Latinos, that would carry him to electoral victory so many times.
