The Caspian expeditions of the Rus' are military raids undertaken by the Rus' between 864 and 1041 on the Caspian Sea shores.

Initially, the Rus' appear in Serkland in the 9th century traveling as merchants along the Volga trade route, selling furs, honey, and slaves.

The first small-scale raids take place in the late 9th and early 10th century.

The Rus' undertake the first large-scale expedition in 913; having arrived on 500 ships, they pillage Gorgan, in the territory of present day Iran, and the adjacent areas, taking slaves and goods.

On their return, the northern raiders are attacked and defeated by Khazar Muslims in the Volga Delta, and those who escape are killed by the local tribes on the middle Volga.During their next expedition in 943, the Rus' capture Bardha'a, the capital of Arran, in the modern-day Republic of Azerbaijan.

The Rus' stay here for several months, killing many inhabitants of the city and amassing substantial plunder.

It is only an outbreak of dysentery among the Rus' that forces them to depart with their spoils.

Sviatoslav, prince of Kiev, commands the next attack, which destroys the Khazar state in 965.

Sviatoslav's campaign establishes the Rus's hold on the north-south trade routes, helping to alter the demographics of the region.

Raids continue through the time period with the last Scandinavian attempt to reestablish the route to the Caspian Sea taking place in 1041 by Ingvar the Far-Travelled.
