By the second half of the 19th century, Shusha had become the largest town in the Karabakh region. However, after the pogrom against the Armenian population in 1920 and the burning of the town, out-migration, and its decreasing economic importance in relation to other regional cities like Yerevan and Baku, Shusha was reduced to a small provincial town of some 10,000 people. Its population afterward progressively dropped year by year, reaching 5,104 by 1926. Armenians did not begin to return until after World War II. It was not until the 1960s that the Armenian quarter began to be rebuilt.
