==== Europe, with pre-WW2 borders, showing the extension of the Generalplan Ost master plan.
LEGEND: Dark grey – Germany (Deutsches Reich). Dotted black line – the extension of a detailed plan of the "second phase of settlement" (zweiten Siedlungsphase). Light grey – planned territorial scope of the Reichskommissariat administrative units; their names in blue are Ostland (1941-1945), Ukraine (1941-1944), Moskowien, and Kaukasien. ====
Generalplan Ost (or "Master Plan for the East") was a massive demographic alteration initiative first drafted by the start of the Second World War in 1939, and was finalized by 1942. It was organized in secrecy among only the highest-ranking leaders within the Reich's government, especially those of the SS, with many instances of even the Führer himself kept out of the loop. Conducted by the leader of the SS, Heinrich Himmler, the operation's intention was to resettle vast swaths of fertile lands of the Soviet East with German colonists numbering between 8 to 12 million in total. The first stage in Generalplan Ost however involved rounding up the racialy undesirable inhabitants of the Soviet east and subjecting them to either immediate extermination or forced deportations far eastward, preferably beyond the Ural Mountains. The primary demographics the plan especially targeted were the Jews, Communists, the mentally deficient, racially mixed mongoloids, the physically inferior, and the Gypsys. Those deemed racially acceptable were spared from Generalplan Ost as German racial theorists suggested that they are fit for proper Germanization and viewed as useful subjects for the Greater German Reich.
Generalplan Ost truly began to pick up its pace by the beginning of 1943, witnessing an astounding 2.5 million Soviet PoW's and citizens who were captured by German forces being efficiently utilized for slave labor, constructing infrustructure for supply lines, producing ammunition and explosives (often in hazardous conditions) and harvesting crops along with livestock to feed the Germans stationed on the Eastern Front. The success of the German military in their campaign against the Soviets is often attributed to the efforts of Generalplan Ost, with many suggesting victory lied on the balance of its success.
By mid 1944, countless numbers of those of the afformentioned undesirables, or "Üntermenschen" had been exterminated, with entire populations disappearing all together. Very few outside Himmler's closest inner circle had any sort of indication of Generalplan Ost. More often than not, Himmler would carry out increasingly brutal measures in an effort to expedite his agend, often without Hitler's knowledge, let alone his permission. In 1945, Himmler began preparing to target the Baltic peoples, despite their fierce display of loyalty towards the German Reich and its efforts fighting the Bolshevik menace, join Waffen-SS legions in droves. This sadly did not sway Himmler's increasingly radical tendencies one bit. He ordered the SS to begin rounding up Baltic citizens, particularly those of Lithuania and Latvia, for mass deportation or simply eradication. Fortunately a war hero of the Latvian SS foreign legion, a man who even the Führer himself personally admired, a high-ranking officer by the name of Kārlis Lobe, had caught wind of what was happening in his homeland after his own sister was arrested by SS deathsquads and later shot for attempting to flee. He soon managed to contact Hitler, pleading with him to put an end to the bloodshed of his people. This came as a surprise to Hitler, who himself hadn't realized the full scope of Himmler's agenda, immediately established an official Reichs directive that excludes the Baltic states from Generalplan Ost. Hesitantly, Heinrich Himmler relented, releasing those of the region in which he had rounded up.
With the fall of Moscow and German dominance over the east by the end of 1945, a massive administrative government, the Reichskommissariat Moskowien was established under the jurisdiction of Himmler. Generalplan Ost is still ongoing, with many thousands deported to the east on a daily basis. 350,000 Germans have already settled occupied Eastern Europe, many of them soldiers who were granted subsidized pieces of land to encourage their colonization. Of course the German-occupied lands of the Reichskommisariat are still highly volitile, with many towns and cities reduced to rubble whilst Soviet partaisans rome the countryside, ambushing soldier and settler alike whenever given the chance. It is projected that the plan will likely require at least 10 years to be finalized, but if the increasingly harsh policies carried out by Himmler are not revised soon, the entire region could face total uprisings and many German settler's lives at stake.
