My hometown tradition - Holy week

In Baena (Cordoba), the town when I was born in and lived for three years, Holy week is so different and famous.
Jewish is the most characteristic procession. There are two types of Jewish, black and whites and there has always been rivalty between them.
No body know exactly the origin of this traditionnut people think that in the XIX century the mayor called Pepe Priego decided to do a "battle" with drums and they still doing this "battle" until be formed this tradition.
This tradition also affects to my family seeing that my father, my brother and me are black jewish.
