With the United States in the grip of a crisis over immigration, the experience of California in the 1990s offers some historical context.

That was when California was experiencing, in the words of Manuel Pastor, a sociologist at the University of Southern California, its own “Trump moment”: a time of rapid demographic change with an influx of Latinos, and a Republican-led effort to deny services to undocumented immigrants and ban bilingual education.

“One kind of signal of California having its own Trump moment is demographic change in California between 1980 and 2000 is the demographic change the United States is going through between 2000 and 2050,” Mr. Pastor said.

Mr. Pastor recently wrote a book on President Trump and California, “State of Resistance,” and in an interview talked about how California’s dysfunction in the 1990s presaged what is happening now.
