Today. the Ninth of October (el Nou d'Octubre), is the national day of the Valencians, a holiday throughout the Valencian Community, which consists of the Spanish provinces of Valencia, Alicante and Castellón. It commemorates the bloodless entry by the Christian monarch James I into the Moorish city of Balansiyya in 1238. James was king of Aragon; that's why the flag of Valencia, the Senyera (shown above) is based on the heraldic arms of Aragon.
In previous years, this blog has celebrated the day with a historical post about it. This year here's something different: a brief introduction to the Valencian language. It takes the form of the lyrics to the Valencian national anthem. There's a truly rousing performance of it on YouTube, sung by the popular Valencian singer Francisco; and with it the lyrics in Valencian and Spanish. To see it and listen to it, click [HERE] or go to https://www.youtube.com/watch?v=esDfiT4H_XM. It's accompanied by a typical Valencian band (banda); there's one in every town and village of any size, often with a music school.
There are Wikipedia articles on Senyera and James I of Aragon.
