He wrote many books, including The Adventures of Tom Sawyer and The Adventures of Huckleberry Finn. Mark Twain’s own life was interesting enough to be a book. Twain was born in the state of Missouri, near the Mississippi River. He came from a poor family. His father died when he was twelve, so he had to leave school. While he was still a boy he worked as a river boat pilot. He steered boats up and down the long Mississippi River. The Civil War, which started in 1861, made travelling on the Mississippi impossible. Twain then went west to Nevada. There he worked on a newspaper. In 1864 he went to California in search of gold. Twain did not have much luck as a gold miner. He left California to travel in Europe. Twain wrote a book about his trips around Europe. But the most important influence on Twain and his books was the Mississippi River. When Twain finally settled down, he lived in a house with a porch that looked like the deck of a riverboat.
