|This article is about an older version of DF.|
Every fortress starts with an Expedition Leader, a low-grade noble position that is automatically appointed when you start your game. It is not possible to choose a new expedition leader while the current one remains alive. Your first expedition leader is semi-randomly chosen from the starting dwarves. Giving one dwarf social skills will greatly increase the chance that this dwarf is chosen as the leader; otherwise it is completely random.
If your Expedition Leader is slain and you do not choose a new one from the obles screen, a new dwarf will be automatically, semi-randomly designated for the job after about half a season.
When the population of a fort reaches 50, the expedition leader becomes the Mayor.
