Aragon is a independent democratic nation. It is overwhelmingly Catalan with a muslim Andalusi minority concentrated near Valencia and the Balearics. Its basically a Catalan nation-state. Its history after the 1700s is pretty bleak, with powerful neighbors interfering in its affairs, preventing it from ever regaining even a modest level of its former glory. It is now one of Europes most stable modern democracies, with a thriving tourism sector and tech industry. Not that everything is perfect. There is a great deal of political gridlock, some serious environmental problems in the urban areas on the Iberian mainland, and deep inequality between social classes.
The entire modern phenomenae of Sunni jihadism does not exist in the same way in this timeline. The modern Mideast is poor, violent, and deeply divided between awkwardly shaped colonial states, but there is less global energy poured into the region. Oil is less valuable in this timeline with a greater reliance on alternative energy sources from the get-go, so that alone reduces the regions importance. Radical Islamic militant movements exist as disparate revolutionary movements across the region, but do not make a consious effort to promote a sort of 'global jihad'. Groups closer to something like Hamas, or Hezbollah (though its shia but the overall concept stands), are much more common ATL. There is no Iranian revolution, no rise of the House of Saud, no Al-Qaeda, no daesh / ISIL etc.
They're both puritanical strains of Sunni Islam, so some confusion is understandable.
ITTL you do have more Mahdist movements world-wide. Especially in the New World, radical groups have been a thorn in the side of Misican officials for decades. Misica even fueled these groups in its frontier regions for decades to serve as proxy fighters where the central government was unwilling to devote troops. There is a deep, long tradition of millenarian armed groups in Islamic Amerindian societies which exists to the present day ATL. ATL Arizona is basically OTL northern Mali lol.
