The three website I used in my research are:
The Jewish Virtual Library
This is a website sponsored by the Weisenthal Center. There are references, an other and you can open links. Also it's a .org making this website is very credible.
PBS
This website is funded by Alfred P. Soloan Foundation. It has references to the author and there's a currency making it credible.
The History Channel
This website is a respected site that takes an honest look at questions based on historical evidence. This site has an author, the date of when the article was written, and the hyperlink works, making this another credible website.
What I found!
The first website talked about his early life; he was born in Braunau am Inn, Austria, on April 20, 1889. The text talked about how he was like growing up; saying he was a resentful, discontented child. As a teenager he wanted to be a painter, but later on he got rejected by the Viennese Academy of Fine Arts. In the next section, it talked about World War 1, where Hitler left Vienna for Munich and when war broke out in August 1914, he joined the Sixteenth Bavarian Infantry Regiment, serving as a dispatch runner. Later he became a leader; Hitler discovered a powerful talent for oratory as well as giving the new Party its symbol — the swastika and was recognized as Fuhrer of a movement which had 3,000 members, and boosted his personal power by organizing strong- arm squads to keep order at his meetings and break up those of his opponents. Throughout the website, it goes in order, from him as a Fuher to World War 2 to the Allied Victory and his death.
The second website overall talked about him as a leader in Germany and how he rise in power as well. It has the same information as in website number one. Another added information that wasn't in website number one was the mentioning of his wife, Eva Braun. Another one was the mentioning of his death; "The following day, Hitler shot himself in the mouth and his wife of less than 24 hours took a fatal dose of poison. Their bodies were carried outside and torched" (Website #2).
The third website simply restated website number one as to the question of who was Adolf Hitler. Such as how he rise in power, what he did in World War 1, and how he took control of Germany and the Jews. It also talked about his military, which countries they were allied with. The text says that Hitler mostly blamed the Marxists and Jews for the loss of World War 1. His attack on Poland in 1939 started World War II and by 1941 Germany occupied much of Europe and North Africa. The tide of the war turned following an invasion of Russian and the U.S. entry into battle, and Hitler killed himself shortly before Germany’s defeat.
