Black death disease decreased population in Europe by 30-60% and worldwide by 10-20%. It shocked religious, social and cultural life of that time. Many people blamed various groups for invoking the plague (i.e. Jews, monks, pilgrims, beggars, foreigners etc. what caused many oppressions. Also lepers had been often isolated and killed.
