What is the real answer of what is the purpose of Kwanzaa?

Maulana Karengacreated Kwanzaa in 1966 as the first specifically African-American holiday.Karenga said his goal was to "give Blacks an alternative to the existing holiday and give Blacks an opportunity to celebrate themselves and their history, rather than simply imitate the practice of the dominant society."
During the early years of Kwanzaa, Karenga said that it was meant to be an alternative toChristmas, thatJesuswas psychotic, and thatChristianitywas "a white religion which black people should shun".As Kwanzaa became more popular, Karenga modified his stand to avoid alienating African-American Christians. In 1997 he backtracked on his original statements and declared:
"Kwanzaa was not created to give people an alternative to their own religion or religious holiday."

Most African-Americans who celebrate Kwanzaa do so as a celebration of their heritage and the 7 principles that it espouses so that is now the real purpose of Kwanzaa. It is very common for those celebrating Kwanzaa to also celebrate Christmas.
