Brazil is a country that has very interesting culture which is the result of the mixing of several different cultures. What is now Brazil has been colonized by the Portuguese people. As they did, they started to settle in, but it was not just Portuguese that settled, there was also lot of Italians as well. As they were the ones that controlled this area, they set up the basis for the modern day culture of Brazil. But that is not all. The colonists encountered lot of native tribes, and over time the natives and the Europeans started to mix. Also, the colonists brought lot of African slaves too, and once the slavery ended, they too started to mix with the Europeans and natives. Each of the three sides contributed with their own cultures, gradually creating one melt resulting in the modern day Brazilian culture. Some of the well known traits of the Brazilian culture is the dancing, carnivals, masquerades, practicing of old traditions, being passionate Catholics, having excellent football skills based on the ginga etc. The ethnic composition too has been influenced in the same manner through the mixing of the people from three different races, making the modern day average Brazil having genes from three sides of the world.
