Sarajevo's economy reached its peak in the 1980s, thanks in large part to the culmination of several decades of industrial development and a tourist boom following the Olympics, as well as increased international investment. During the Siege of Sarajevo, the Bosnian Serb forces often targeted structures key to the city’s economic health, including the headquarters of companies and many services and public utilities. Since then, the Sarajevo economy has made tremendous progress, significantly better than its post-war state in 1996.
