Adolf Hitler wrote Mein Kampf (German for "My Struggle") while imprisoned in Landsberg Prison after his failed Beer Hall Putsch of 1923. The first volume was published in 1925 and the second in 1926. The book outlined Hitler's political ideology, including his views on race, nationalism, and his vision for Germany's future. It became a foundational text of the Nazi movement.
The other works listed belong to entirely different authors and intellectual traditions. The Communist Manifesto was written by Karl Marx and Friedrich Engels in 1848 as a call for proletarian revolution. The Wealth of Nations was authored by Adam Smith in 1776 and is considered a founding text of classical economics. Das Kapital was Karl Marx's major work on political economy, with the first volume published in 1867.
Exam tip: Associate each of these landmark political and economic texts with its author: Hitler with Mein Kampf, Marx and Engels with The Communist Manifesto, Adam Smith with The Wealth of Nations, and Marx with Das Kapital.
