Mack launched a rebuilding program in the mid-1920s, and his effort became "The Second Dynasty", which culminated in back-to-back-to-back AL pennants in 1929, 1930 and 1931. It was an ill-timed hegemony, though: the Wall Street Crash of 1929 triggered the Great Depression, and hard times caused baseball attendance to plummet, winners or no. By October 1932, the second great sell-off, of The Second Dynasty, was underway; by 1935, the stars were gone and the franchise had picked up $545,000 cash for itself. The A's had won the last of their pennants (and would not go to the postseason again until 1971, when they were in Oakland), and goodwill with the fan base was in short supply indeed.
