1360 - Spanish castle magic

In 1360, in Andalusia
(Southern Spain), they were building a great fort
And a kingly palace, the Alhambra
As the Christians closed in, and the Moors bought
Time to retain their Muslim kingdom, caught
In their southern pocket, where they would stay
Till 1492, so not a short
Time they enjoyed Granada's luxury
Meanwhile, Muhammad V became prey
To a coup by Ismail, his half-brother
Who was killed by Muhammad VI, but
He in turn was killed in Seville; they say
Pedro the Cruel sent his head as a
Gift to Muhammad V, now restored
