Historically, Canada has been influenced by British, French, and Indigenous cultures and traditions. Through their language, art and music, Indigenous peoples continue to influence the Canadian identity. During the 20th century, Canadians with African, Caribbean and Asian nationalities have added to the Canadian identity and its culture. Canadian humour is an integral part of the Canadian identity and is reflected in its folklore, literature, music, art, and media. The primary characteristics of Canadian humour are irony, parody, and satire. Many Canadian comedians have achieved international success such as in the American television and film industries and are amongst the most recognized in the world.
