Algiers

Algiers was the capital city of Algeria.

In 1511, King Samis El Felipe was captured by the king of Spain, and Ottoman Assassins sent from Constantinople by the Italian Mentor Ezio Auditore corresponded with him while he was in prison, via exchanging letters back and forth in order to keep in contact with him.

The amir Selim of Algiers also proposed to turn a blind eye to the activities of the Assassins in Algiers in return for protection of a community of Moors living on the island Penon, captured by the Spanish.

Also, the Ottoman Assassins took over Algiers from Templar control, and restored and expanded the city, installing several Assassin Dens in the process.
