These troubles were followed in 1347 by the Black Death, a pandemic that spread throughout Europe during the following three years.[AC] The death toll was probably about 35 million people in Europe, about one-third of the population. Towns were especially hard-hit because of their crowded conditions.[AD] Large areas of land were left sparsely inhabited, and in some places fields were left unworked. Wages rose as landlords sought to entice the reduced number of available workers to their fields. Further problems were lower rents and lower demand for food, both of which cut into agricultural income. Urban workers also felt that they had a right to greater earnings, and popular uprisings broke out across Europe. Among the uprisings were the jacquerie in France, the Peasants' Revolt in England, and revolts in the cities of Florence in Italy and Ghent and Bruges in Flanders. The trauma of the plague led to an increased piety throughout Europe, manifested by the foundation of new charities, the self-mortification of the flagellants, and the scapegoating of Jews. Conditions were further unsettled by the return of the plague throughout the rest of the 14th century; it continued to strike Europe periodically during the rest of the Middle Ages.

Although not without conflict, European/Canadian early interactions with First Nations and Inuit populations were relatively peaceful compared to the experience of native peoples in the United States. Combined with a late economic development in many regions, this relatively peaceful history has allowed Canadian Indigenous peoples to have a fairly strong influence on the early national culture while preserving their own identity. From the late 18th century, European Canadians encouraged Aboriginals to assimilate into their own culture, referred to as "Canadian culture". These attempts reached a climax in the late 19th and early 20th centuries with forced integration. National Aboriginal Day recognises the cultures and contributions of Aboriginal peoples of Canada. There are currently over 600 recognized First Nations governments or bands encompassing 1,172,790 2006 people spread across Canada with distinctive Aboriginal cultures, languages, art, and music.
What have Canadian indigenous peoples been able to have a strong influence on?
A: national culture
