Dorothea Lange in the context of "Internally displaced person"

The 1930s (pronounced "nineteen-thirties" and commonly abbreviated as "the '30s" or "the Thirties") was a decade that began on January 1, 1930, and ended on December 31, 1939. In the United States, the Dust Bowl led to the nickname the "Dirty Thirties".

The decade was defined by a global economic and political crisis that culminated in the Second World War. It saw the collapse of the international financial system, beginning with the Wall Street crash of 1929, the largest stock market crash in American history. The subsequent economic downfall, called the Great Depression, had traumatic social effects worldwide, leading to widespread poverty and unemployment, especially in the economic superpower of the United States and in Germany, which was already struggling with the payment of reparations for the First World War. The Dust Bowl in the United States (which led to the nickname the "Dirty Thirties") exacerbated the scarcity of wealth. U.S. President Franklin D. Roosevelt, who took office in 1933, introduced a program of broad-scale social reforms and stimulus plans called the New Deal in response to the crisis. The Soviet Union's second five-year plan gave heavy industry top priority, putting the Soviet Union not far behind Germany as one of the major steel-producing countries of the world, while also improving communications. First-wave feminism made advances, with women gaining the right to vote in South Africa (1930, whites only), Brazil (1933), and Cuba (1933). Following the rise of Adolf Hitler and the emergence of the NSDAP as the country's sole legal party in 1933, Germany imposed a series of laws which discriminated against Jews and other ethnic minorities.

An internally displaced person (IDP) is someone who is forced to leave their home but who remains within their country's borders. They are often referred to as refugees, although they do not fall within the legal definitions of a refugee.

In 2022, it was estimated there were 70.5 million IDPs worldwide. The first year for which global statistics on IDPs are available was in 1989. As of 3 May 2022, the countries with the largest IDP populations were Ukraine (8 million), Syria (7.6 million), Sudan (7.3 million), Ethiopia (5.5 million), the Democratic Republic of the Congo (5.2 million), Colombia (4.9 million), Yemen (4.3 million), Afghanistan (3.8 million), Iraq (3.6 million), South Sudan (1.9 million), Pakistan (1.4 million), Nigeria (1.2 million) and Somalia (1.1 million). More than 85% of Palestinians in Gaza (1.9 million) were internally displaced as of January 2024.

Documentary photography usually refers to a popular form of photography used to chronicle events or environments both significant and relevant to history and historical events as well as everyday life. It is typically undertaken as professional photojournalism, or real-life reportage, but it may also be an amateur, artistic, or academic pursuit. Social documentary photography aims to draw the public's attention to social issues or to the life of underprivileged people.

Florence Owens Thompson (born Florence Leona Christie; September 1, 1903 – September 16, 1983) was an American woman who was the subject of Dorothea Lange's photograph Migrant Mother (1936), considered an iconic image of the Great Depression. The Library of Congress titled the image: "Destitute pea pickers in California. Mother of seven children. Age thirty-two. Nipomo, California." Thompson was called the "Mona Lisa of the 1930s."

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of natural factors (severe drought) and human-made factors: a failure to apply dryland farming methods to prevent wind erosion, most notably the destruction of the natural topsoil by settlers in the region. The drought came in three waves: 1934, 1936, and 1939–1940, but some regions of the High Plains experienced drought conditions for as long as eight years. It exacerbated an already existing agricultural recession.

The Dust Bowl has been the subject of many cultural works, including John Steinbeck's 1939 novel The Grapes of Wrath; the Dust Bowl Ballads of Woody Guthrie; and Dorothea Lange's photographs depicting the conditions of migrants, particularly Migrant Mother, taken in 1936.

Migrant Mother is a photograph taken in 1936 in Nipomo, California, by American photographer Dorothea Lange during her time with the Resettlement Administration (later the Farm Security Administration). The 28.3 by 21.8 cm (11 1/8 by 8 9/16 in) gelatin silver print depicts a mother anxiously gazing into the distance, with an infant in her lap and two older children huddling close by. The photo captures the plight of migrant farm workers who arrived in California en masse looking for employment during the Great Depression. Initially anonymous, the woman in the photo was identified as Florence Owens Thompson in 1978, following the work of a journalist for the California-based newspaper The Modesto Bee.

Since its publication, Lange's work has been considered symbolic of the Great Depression. It is in the public domain and has been widely reproduced in educational material, advertisements, and other media. Today, Migrant Mother is considered to be a part of the classic canon of American art and international photography. A print is housed at the Museum of Modern Art in New York City.
