When the Wall Street Crash of 1929 struck less than eight months after he took office, Hoover tried to combat the ensuing Great Depression in the United States with large-scale government public works projects such as the Hoover Dam, and calls on industry to keep wages high.
In 1929 Herbert Hoover became the 31st president of the United States. Soon after his election the country sank into the Great Depression. Hoover had helped many starving people in Europe during World War I (1914-18). However, he could not help the millions of U.S. citizens who lost their jobs during the depression.
