Nazi Party
"Deutsche Gemeinschaft" was a branch of the Nazi Party founded in 1919, created for Germans with "Volksdeutsche" status. It is not to be confused with the post-war right-wing "", which was founded in 1949.
Reichswehr
The Nazi Party came to power in Germany in 1933. The "Sturmabteilung" (Storm Battalion or SA), the Nazi Party militia, played a prominent part in this change. Ernst Röhm and his SA colleagues thought of their force — at that time over three million strong — as the future army of Germany, replacing the smaller "Reichswehr" and its professional officers, whom they viewed as old fogies who lacked revolutionary spirit.
Röhm wanted to become Minister of Defense, and in February 1934 demanded that the much smaller "Reichswehr" be merged into the SA to form a true people's army. This alarmed both political and military leaders, and to forestall the possibility of a coup, Hitler sided with conservative leaders and the military. Röhm and the leadership of the SA were murdered, along with many other political adversaries of the Nazis, including two Reichswehr generals, in the Night of the Long Knives (30 June – 2 July 1934).
