Explanation:

The Great Depression, also known as the Crisis of 29, was a great global economic crisis that lasted during the 1930s, in the years before the Second World War. Its duration depends on the countries analyzed, but in the majority it began around 1929 and lasted until the late 1930s or early 1940s. It was the longest depression in time, of greater depth and the one that affected more countries in the 20th century. In the 21st century it has been used as a paradigm of the extent to which a serious deterioration of the economy on a world scale can occur.

The so-called Great Depression originated in the United States, after the stock market crash on Tuesday, October 29, 1929 (known as Crac on the 29th or Black Tuesday, although five days earlier, on October 24, the Thursday Black), and quickly spread to almost every country in the world.

The depression had devastating effects in almost all countries, rich and poor, where insecurity and misery were transmitted as an epidemic, so that they fell: national income, tax revenues, business profits and prices. International trade fell between 50% and 66%. Unemployment in the United States increased to 25%, and in some countries it reached 33%. Cities around the world were severely affected, especially those that depended on heavy industry, and the construction industry came to a virtual halt in many areas. Agriculture and rural areas suffered from falling crop prices, which reached approximately 60%. Given the fall in demand, the areas dependent on the primary sector industries, with few alternative sources of employment, were the most affected.

Countries began to recover progressively in the mid-1930s, but their negative effects in many areas lasted until the beginning of World War II. The election of Franklin D. Roosevelt as president and the establishment of the New Deal in 1932 marked the beginning of the end of the Great Depression in the United States. However, in Germany, the disappearance of foreign financing in the early 1930s and the increase of economic difficulties, led to the emergence of national-socialism and the arrival of Adolf Hitler to power.
