   Blacks first came to America from Africa as slaves. President Lincoln freed the slaves in 1863. About eleven percent of the present American population is black.
   The first immigrants in American history came from England and Netherlands. Soon immigrants began to arrive from many other countries, and they are still arriving. In 1790, the new nation had fewer than four million. Today, there are more than 210 million. These include people from all parts of the world.
