the concept of tipping points that help you understand the essential features of life in Texas between 1890 and 1940? TEXAS HISTORY 1900-

I have mentioned several times in class the concept of tipping points as moments when change became more obvious but not absolute.  Change and persistence existed together, but new directions became a bit clearer.  For example, the passage of the Poll Tax Amendment of 1902 can be seen as a moment when laws that made voting more onerous drastically reduced voter participation reversing a fifty-year trend.  Yet when it really mattered to voters such as in the 1911 vote on a state prohibition amendment turnout remained fairly high.  Using a past forward approach can you give me some other examples of tipping points between 1890 and 1940?  Does thinking about tipping points as moments of both persistence and change help you understand the essential features of life in Texas between 1890 and 1940?  Draw on lectures, previous discussion posts, and Sharpless, Fertile Ground, Narrow Choices, in making evidence based observations.  I have attached a picture that might help you think about tipping points.
