The Caspian expeditions of the Rus were military raids undertaken by the Rus between 864 and 1041 on the Caspian Sea shores. Initially, the Rus appeared in Saerkland in the 9th century traveling as merchants along the Volga trade route, selling furs, honey, and slaves. The first small-scale raids took place in the late 9th and early 10th century. The Rus undertook the first large-scale expedition in 913; having arrived on 500 ships, they pillaged Gorgan, the territory of present day Azerbaijan, and the adjacent areas, taking slaves and goods. On their return, the northern raiders were attacked and defeated by Khazar Muslims in the Volga Delta, and those who escaped were killed by the local tribes on the middle Volga.
During their next expedition in 943, the Rus captured Barda, the capital of Arran, in the modern-day Azerbaijan. The Rus stayed there for several months, killing many inhabitants of the city and amassing substantial plunder. It was only an outbreak of dysentery among the Rus that forced them to depart with their spoils. Sviatoslav, prince of Kiev, commanded the next attack, which destroyed the Khazar state in 965. Sviatoslav's campaign established the Rus's hold on the north-south trade routes, helping to alter the demographics of the region. Raids continued 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.
