ISTANBUL — IN the upscale Istanbul suburb of Bebek, at 9 p.m. sharp, the diners began drumming on the tables or tapping their wineglasses with forks. The traffic passing along the Bosporus chimed in with honking horns and flashing headlights. It was a genteel symphony of solidarity with the protesters who a few days earlier were confronting fire hoses and tear gas in the heart of the city and elsewhere around Turkey.

Those street battles that caught our attention this summer have mostly been policed into submission, and the world’s cameras have moved on, but the afterlife is interesting.

What is happening in Turkey is not “Les Miserables,” or the Arab Spring. It is not an uprising born in desperation. It is the latest in a series of revolts arising from the middle class — the urban, educated haves who are in some ways the principal beneficiaries of the regimes they now reject.

We saw early versions of it in China in 1989, Venezuela in 2002. We saw it in Iran in 2009, when the cosmopolitan crowds thronged in protest against theocratic hard-liners. We saw it in Russia in 2011, when legions of 30-somethings spilled out of their office cubicles, chanting their scorn for the highhanded rule of Vladimir Putin. While Turkey was still percolating, the discontent bubbled up in Brazil, where yet another ruling party seems to be a victim of its own success.
