Changes in the First 15 Years of the 20th Century Europe

The first 15 years of the 20th century shows the changes in the theory and practice of contemporary artists in Western European countries. The first 15 years are surprising compared to their great and advanced science and technology. Now is the era of Western European culture growth and rapid industrialization and competition of the European empire. In the 20th century, Paris became the focus of modernism. In the 19th century scientists discovered this theory.

The emergence of the first women's movement, or the first wave of so-called feminism, dates back to the early 20th century from the late nineteenth century in America and Europe. Meanwhile, the first series of feminist movements evolved from the background of "industrial society and liberal politics", leading to a "feminist group", focusing on equal opportunities and women's opportunities. : 1 This wave represents women's "voting rights, independence, nationality, work, equal salary"

Two changes are possible explanations. One is a depression that occurred in the typical era of the early adolescence of the 20th century. At the beginning of the 20th century, the median age of menarche in Western countries was about 15 years old (Eveleth & Tanner, 1976). This means that early changes in most adolescent people begin around 13 to 15 years old, as menarche occur relatively late in a typical sequence of puberty changes. Here Hall specifies the beginning of puberty. However, since the median of menarche age (and suggesting changes in other adolescents) steadily declined between 1900 and 1970 and then stabilized, the typical menarche age in the US is currently 12.5 years old (Brooks-Gunn & Paikoff, 1997). Early changes in puberty usually begin two years ago, so designation of puberty begins 20 years later.
