White Americans are people who have ancestors from Europe and who have white skin. They are called "white" because their skin color is usually lighter than people from other races.
America was originally inhabited by Native Americans, but white people started to come to America a few hundred years ago, mostly from Europe. When they came, they brought their own cultures and traditions with them.
Since then, white Americans have been a big part of American society. They have made up a majority of the population for a long time and have had a lot of power and influence in the country.
However, it's important to note that not all white Americans have had the same experiences or been treated equally. Some white Americans have faced discrimination because of their religion, ethnicity, or sexual orientation.
Overall, being a white American means having ancestors from Europe and being part of a group that has played a big role in shaping American culture and society.
