In the Middle Ages, the Volga trade route connected Northern Europe and Northwestern Russia with the Caspian Sea and the Sasanian Empire, via the Volga River. The Rus used this route to trade with Muslim countries on the southern shores of the Caspian Sea, sometimes penetrating as far as Baghdad. The powerful Volga Bulgars (cousins of today's Balkan Bulgarians) formed a seminomadic confederation and traded through the Volga river with Viking people of Rus' and Scandinavia (Swedes, Danes, Norwegians) and with the southern Byzantine Empire (Eastern Roman Empire) Furthermore, Volga Bulgaria, with its two cities Bulgar and Suvar east of what is today Moscow, traded with Russians and the fur-selling Ugrians. Chess was introduced to Medieval Rus via the Caspian-Volga trade routes from Persia and Arabia.

There was a second route from the Baltic Sea to the Dnieper, which ran along the Western Dvina (Daugava) between Lovat and Dnieper in the Smolensk region and along the Kasplya River to Gnezdovo. The Volga trade route functioned concurrently with the Dnieper trade route, better known as the trade route from the Varangians to the Greeks, and lost its importance in the 11th century.

The Ballets Russes (French: [balɛ ʁys]) was an itinerant ballet company begun in Paris that performed between 1909 and 1929 throughout Europe and on tours to North and South America. The company never performed in Russia, where the Revolution disrupted society. After its initial Paris season, the company had no formal ties there.

Originally conceived by impresario Sergei Diaghilev, the Ballets Russes is widely regarded as the most influential ballet company of the 20th century, in part because it promoted ground-breaking artistic collaborations among young choreographers, composers, designers, and dancers, all at the forefront of their several fields. Diaghilev commissioned works from composers such as Igor Stravinsky, Claude Debussy, Sergei Prokofiev, Erik Satie, and Maurice Ravel, artists such as Vasily Kandinsky, Alexandre Benois, Konstantin Korovin, Nicholas Roerich, Pablo Picasso, and Henri Matisse, and costume designers Léon Bakst, Ivan Bilibin and Coco Chanel.

The Rite of Spring (French: Le Sacre du printemps) is a ballet and orchestral concert work by the Russian composer Igor Stravinsky. 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. Many have called the first-night reaction a "riot" or "near-riot", though this wording did not come about until reviews of later performances in 1924, over a decade later. 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.

Stravinsky was a young, virtually unknown composer when Diaghilev recruited him to create works for the Ballets Russes. Le Sacre du printemps was the third such major project, after the acclaimed Firebird (1910) and Petrushka (1911). The concept behind The Rite of Spring, developed by Roerich from Stravinsky's outline idea, is suggested by its subtitle, "Pictures of Pagan Russia in Two Parts"; the scenario depicts various primitive rituals celebrating the advent of spring, after which a young girl is chosen as a sacrificial victim and dances herself to death. After a mixed critical reception for its original run and a short London tour, the ballet was not performed again until the 1920s, when a version choreographed by Léonide Massine replaced Nijinsky's original, which saw only eight performances. Massine's was the forerunner of many innovative productions directed by the world's leading choreographers, gaining the work worldwide acceptance. In the 1980s, Nijinsky's original choreography, long believed lost, was reconstructed by the Joffrey Ballet in Los Angeles.

Champion warfare refers to a type of battle, most commonly found in the epic poetry and myth of ancient history, in which the outcome of the conflict is determined by single combat, an individual duel between the best soldiers ("champions") from each opposing army. Champion warfare can also refer to a battle in which armies actually engage, but champions within the armies fight so effectively as to single-handedly carry the sway of battle, such as in the Iliad.
