What world events occurred while the German Graf Zeppelin made its world tour?

The Graf Zeppelin left New Jersey in its quest to circumnavigate the globe on August 8th and returned on August 29th. This was the fastest circumnavigation of the globe in human history. In many respects, the event can be seen as the final achievement of the Roaring Twenties before the misery of the Great Depression would descend on the world. It was the last of many technological feats from the decade that saw the introduction of radio stations and television, the flight of Charles Lindbergh across the Atlantic Ocean, and liquid fueled rockets.

The most significant event that happened while the zeppelin was in the air occurred in Palestine as Jews and Palestinians quarreled over control of the Western Wall. The violence resulted in two Jewish massacres and the expulsion of Jews from Hebron. The 1929 Palestine Riots resulted in nearly 250 deaths.

The zeppelin was in the air at a time that the stock market was nearing a crash. Less than a week after the flight ended, the Dow Jones reached an all-time high. The market would crash in late October, plunging the United States into a prolonged economic depression. The stock market crash would have repercussions around the world, destroying an already struggling global economy. For this reason, the trip of the Graf Zeppelin was a final achievement of the decade of American prosperity that was the 1920's.
