overthrowing old traditions

Overthrowing old traditions.  Yes, in South Africa there was a time that old traditions were overthrown.  For many years, white people controlled South Africa.  Black people and others fought for their freedom.  Finally, in 1994, there was the first election where everyone could vote.  It is called the liberation.  Now place names have been changed and there are 11 official languages (before there were only 2 official languages - the languages of the white people).
