RIP Talabani. He and Barzani, though their factions often feuded internally, kept Kurdish interests at the forefront in the shaping of the post-Saddam Iraq.
Yes, they did.
There are great differences in the factions.
Talabani was open to secular structure. Barzani not so much.
Syrian Kurds much prefer the Talabani element of Iraq.
I’ve read that 98% of Iraq Kurds are Muslim (Sunni and Shia). I doubt that number.
Syrian Kurds have much smaller percentage of Muslim.
Some time ago I found maps showing religious breakdown in Iraq and Syrian towns/villages. They varry a lot but it is more mixed than most people think.
Some of that is hidden because of persecution.
From the time of the Siege of Kobani, Syriac Christians have fought alongside Kurds against ISIS. It was a matter of survival. It is true with some Arabs too. That came later, but ISIS brutality has reshaped those relations. Some of those open relations existed before ISIS in Syria. It was a long way from Damascus and Rojava. Out of necessity, the people had to cooperate to survive. Interdependence was very common.
