Modern humans are thought to have had a number of "constriction" events where the total population was well below 100K individuals. 100K primitive people don't dominate much of anything. These events happened long after modern humans arose as a species. There is plenty of evidence that much more modern large cultures collapsed from time to time, but we don't always know why. We have almost no data to understand the long history of human success/failures prior to the last 5K years or so, a period quite short relative to our species existence.
