I’m afraid I got the data wrong. I misread my own handwriting. Apologies to Geoffrey Cornelius. I had to adjust it anyway, because my software was acting up, so I’ve redone it on astro.com. Here is the corrected chart. Thanks to Elizabeth Hathaway for pointing this out.
I have also had a look around the web and found several more charts that seem to have just as valid reasoning backing them, so I’m afraid I am back to where I was before, which is I’m really not sure of which chart to use. Personally, I loved yesterday’s — so nasty.
This one does look scary too — although not as chilling as the previous one! — I note this is the date of the announcement of the Caliphate to the press, on the first day of Ramadan.
The fact is this is a rebranding. Here’s a comment from a news website.
Wow, they sure go through a few names.
First it was Tawhid Wal Jihad… then Al-Qaeda in Iraq… then Islamic State of Iraq… then Islamic State of Iraq and the Levant…now it’s The Islamic State.
That’s 5 names in 12 years.
Tricky. And if you’re wondering about caliphates anyway, here’s a link.
