One way in which european women’s economic roles changed during the twentieth century.

  1. Military conflicts are central to understanding the course of the twentieth century and the current system of states and international organizations. The world wars led to rapid advances in technology, including medical technology, which has helped the global population increase to over seven billion. Some current regional conflicts like those in the Middle East are the legacy of the world wars. 
  2. Revolutions and nationalist movements played an important role, especially in the period of de- colonization after WWII. Some existing countries experienced revolutions, like China and Russia, while other countries were created through nationalist movements, like Vietnam. Some current regional conflicts are the legacy of these movements, such as the dispute between India and Pakistan over Kashmir. 
  3. In the second half of the twentieth century into the present, political and economic reforms reshaped interstate relations, and the world economy became more integrated. The fall of the Soviet Union, the opening of Chinese trade with the United States in the 1970s, the formation of the European Union, and the population and industrial growth of states have led to significant structural changes. 
  4. Advances in computer technology, especially the growth of the Internet from the 1990s to the present, have changed economic and social structures. While this technology brought about new ways of communication and has fundamentally changed economies in the developed world, it has also led to new types of crime, such as hacking and identity theft. 
  5. Over the course of the twentieth century, social structures changed to include more rights for minority groups and women. The decline of traditional social structures has been caused by many factors, such as changes in the workforce, new concepts of human rights in the post-WWII period, and the rapid growth and industrialization of the global south. 
  6. Globalization in the economic and cultural spheres also increased, including the advent of mass culture based on new communications technologies like radio, television, and the Internet. This has accelerated changes caused by the other significant events in the period, such as the world wars, the expansion of human rights, and the interconnection of global trade.

The dawn of the twentieth century witnessed changes in almost every aspect of the day-today lives of women, from the domestic sphere to the public. The women's movement, with its emphasis on advocacy of equal rights, newly formed women's organizations, and the rise of a new generation of female artists, photographers, and professionals, transformed the traditional patriarchal social structure across the globe. Followed closely by the advent of World War I, these social shifts, which had been set in motion at the beginning of the century, developed further as women were propelled into the workforce, exposing them to previously male-dominated professional and political situations. By the midpoint of the twentieth century, women's activities and concerns had been recognized as a significant element of the literary, scientific, and cultural landscape of several countries, marking a revolutionary change in the social and domestic roles of women.

The end of the nineteenth century saw tremendous growth in the suffrage movement in England and the United States, with women struggling to attain political equality. The suffragists—who were often militant in their expressions of protest—presented a sometimes stark contrast to the feminine ideal of the era, which portrayed women as delicate, demure, and silent, confined to a domestic world that cocooned them from the harsh realities of the world. Despite many challenges English and American women eventually won the right to vote, in part due to the changed perception of women's abilities following World War I. As men were called to war, companies that had previously limited employment in better-paying jobs to white males found themselves opening their doors to white women and women and men of color. Racial and gender tensions escalated during this time, and many jobs were in fact permanently redefined as "women's work," including teaching, nursing, secretarial work, and telephone operations. As well as functioning in the workforce, women actively participated in the political and cultural life of England and the United States. The early decades of the twentieth century, often referred to as the Progressive Era, saw the emergence of a new image of women in society which had undergone a marked transformation from the demure, frail, female stereotype of the late Victorian Era. The women of the Progressive Era, according to Sarah Jane Deutsch, were portrayed as "women with short hair and short skirts … kicking up their legs and kicking off a century of social restrictions." Progressive women smoked, danced in public, held jobs, and generally did most things that nineteenth-century women were barred from doing. However, Deutsch asserts that this image of the 1920s "flapper" was restricted to certain portions of the population, namely white, young, and middle-class communities. Women elsewhere, particularly women from other ethnic backgrounds, such as African-Americans, Asian-Americans, and Hispanics, lived much differently, struggling in their new roles as mothers and professionals. The number of women who worked outside the home in the 1920s rose almost 50 percent throughout the decade. While women still constituted a small number of the professional population, they were slowly increasing their participation in more significant occupations, including law, social work, engineering, and medicine.

The presence of a large class of young working women after World War I was reflected in what had become a major cultural force—the film industry. Nevertheless, films of the era continued to reinforce outdated stereotypes about women's place in society. While early cinematic storylines often featured poor women finding success and contentment through marriage to rich men, the films of the 1920s depicted young, feisty working women who, like their predecessors, could attain true happiness only by marrying their bosses. Such plotlines helped many to cope with the growing fear that the domestic and family structure of society was being eroded by the emergence of the new, independent woman. Rarely did depictions of women in mass media, including film, radio, and theater, convey the true circumstances of working women. Instead, audiences were presented with images of flappers or visions of glorified motherhood and marriage.

Women in the early twentieth century were perhaps most active and influential as writers and artists. The advent of the new century did witness a change in the style and content of women's writing, as well as an increase in the depiction of feminine images and themes in literature. Male authors such as D. H. Lawrence and W. D. Howells explored issues pertaining to sexuality and the newly redefined sexual politics between men and women. Women authors such as Dorothy Richardson, May Sinclair, and Katherine Mansfield focused on topics pertinent to women, bringing attention to the myriad difficulties they faced redefining their identities in a changing world. Other major women writers of the period included Gertrude Stein, Virginia Woolf, Charlotte Perkins Gilman, and Edith Wharton. In the arena of art, the early twentieth century provided growing opportunities for women to exhibit their work. In 1914, for example, the National Academy of Design first allowed women to attend anatomy lectures, thus providing them with a chance to study draftsmanship and develop drawing skills in a formal setting. Such artists as Emerson Baum and photographers like Alfred Steiglitz helped promote exhibitions of women's art, including the works of Imogen Cunningham and Georgia O'Keefe. Many female artists—among them Dorothea Lange and Claire Leighton—used their talents to highlight the social realities of their times, and some of the most powerful images of this period, including stirring portrayals of coal miners and farmers, were produced by these women.

By the mid-twentieth century, women throughout the Western world had completely redefined their roles in almost every social, political, and cultural sphere. While the fight for equal rights and recognition for women would continue into the 1950s and beyond, the first major steps towards such changes began at the advent of the twentieth century, with women writers, photographers, artists, activists, and workers blazing a new trail for generations of women to follow.
