The Dolchstoßlegende, or "stab-in-the-back myth," was a conspiracy theory popular in Germany after World War I. It claimed that the German Army did not actually lose the war on the battlefield, but was instead betrayed by civilians on the home front, including politicians and Jews. This myth was used to shift blame away from the military and the ruling elite for the defeat in the war, and was used as a tool to undermine the Weimar Republic and justify the rise of right-wing and nationalist movements in Germany. The Dolchstoßlegende contributed to the political instability and social unrest in Germany during the 1920s and 1930s. **

In Germany, hyperinflation reached its peak, leading to a complete collapse of the economy and widespread social unrest. The value of the German mark plummeted, causing severe hardship for the population and leading to political instability. The crisis also had a global impact, as it contributed to economic instability in other countries and strained international relations. Overall, the crisis year of 1923 was a period of great economic and social upheaval, with far-reaching consequences for many nations. **

The Ruhrkampf of 1923 was discontinued because it had severe economic consequences for Germany. The French occupation of the Ruhr region led to hyperinflation and economic instability, causing widespread suffering among the German population. The German government eventually decided to end the passive resistance in the Ruhr to prevent further economic collapse and social unrest. Additionally, diplomatic efforts were made to negotiate a resolution to the crisis, leading to the Dawes Plan in 1924. **

The Ruhrkampf of 1923 was terminated because of the economic and political pressure it placed on Germany. The French occupation of the Ruhr region led to a significant loss of revenue for the German government, exacerbating the already dire economic situation. Additionally, the German government's decision to call off the passive resistance in the Ruhr was influenced by the growing internal unrest and the realization that the strategy was not achieving its intended goals. Ultimately, the termination of the Ruhrkampf was a pragmatic decision to alleviate the economic strain and internal turmoil facing Germany at the time. **

Yes, Greeks lived in what is now modern-day Turkey for thousands of years before 1923.

Today, there are still some Greeks living in Turkey, particularly in Istanbul and the islands near the Turkish coast. **

In terms of societal norms, values, and advancements, there have been significant changes between the two time periods. **
