In Kosovo, the destruction of historical architecture occurred within the context of the Serbian campaign of ethnic cleansing which followed a pattern that happened in Bosnia and was made worse, due to lessons of efficiency learned from that conflict. The destruction of non-Serbian architectural heritage was a methodical and planned component of ethnic cleansing in Kosovo. Harvard University scholars Andrew Herscher and András Riedlmayer note that the destruction of individual homes and properties in addition to historic architecture signified that the entire Kosovo Albanian population was targeted as a culturally defined entity during the conflict.
