Texag57, you’re misinformed. The unit that was to become the Grossdeutschland Division, <i>Wachregiment Berlin</i> (Guard Regiment Berlin), was originally formed in early 1921 to protect the Weimar Republic (or, more accurately, the capital) from the threat of both Fascists and Communists. <br /><br />
In June of the same year, it was disbanded and recreated as the <i>Kommando der Wachtruppe</i> (Command of the Guard Troops), with the same function but increased size.<br />
This Guard Troop now drew one company from each of Germany’s seven divisions, turning it into a demographic representation of the entire <i>Reichswehr</i> of the time. <br /><br />
After the Nazi-takeover, it was renamed to <i>Wachtruppe Berlin</i> in 1934, then in 1937 it was returned to its original name of <i>Wachregiment Berlin</i>. <br />
It wasn’t until the first week of 1939 that this regiment was renamed to be the <i>Infantrieregiment Grossdeutschland</i>, from which point on it had a permanent cadre of troops drawn from all over Germany, unlike other German Heer regiments which would draw recruits from specific regions. <br /><br />
On a side note: Despite the SS’s role as Hitler’s bodyguard, his actual private bodyguards were drawn from <i>Grossdeutschland</i>, the so-called <i>Fuehrer Begleit</i>. This was done as a favor to the Heer command, as it demanded to provide the personal guard to the Leader of Germany, as it had historically always done.
