After Iraqi Kurds held an independence referendum last month, the government in Baghdad — which deemed the vote unconstitutional — sent in troops. It wasn't the first time Kurds have pushed toward independence, only to be beaten.
Why it matters: It's likely not the last time, either. The complicated history behind the regional struggle spans across decades and borders, and Kurdish support for independence are coming to a head, not just in Iraq, but in neighboring countries as well.
