Nazi Germany Germany from 1933 to 1945 while under control of the Nazi Party

Nazi Germany, officially known as the German Reich until 1943 and Greater German Reich in 1943–45, was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country which they transformed into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazis' conceit that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand Year Reich, ended in May 1945 after just 12 years, when the Allies defeated Germany, ending World War II in Europe.

Pop is a genre of popular music that originated in its modern form during the mid-1950s in the United States and the United Kingdom. The terms popular music and pop music are often used interchangeably, although the former describes all music that is popular and includes many disparate styles. During the 1950s and 1960s, pop encompassed rock and roll and the youth-oriented styles it influenced. Rock and pop remained roughly synonymous until the late 1960s, after which pop became associated with music that was more commercial, ephemeral, and accessible.

Rock music is a broad genre of popular music that originated as "rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles in the mid-1960s and later, particularly in the United States and the United Kingdom. It has its roots in 1940s and 1950s rock and roll, a style that drew heavily from the genres of blues, rhythm and blues, and from country music. Rock music also drew strongly from a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical, and other musical styles. For instrumentation, rock has centered on the electric guitar, usually as part of a rock group with electric bass, drums, and one or more singers. Usually, rock is song-based music with a 4

<i>Matthevia</i>

Matthevia is a genus of Cambrian molluscs, perhaps related to the chitons. It consists of repeated monoplacophoran-like shells; according to one hypothesis, chitons arose when these tall shells began to overlap over the generations. The tall element of the shell was retained and forms the tips of modern chiton plates. There are distinct head, 'centre', and tail valves, which occur approximately in the ratio 1:5:1 — suggesting a seven-plated configuration.
