Hi! If your Leader did not log in into the game for more than 3 weeks, you can submit a ticket to our Support Team: https://plarium-mobile-support.zendesk.com/hc/en-us/requests/new and they will guide you through the process.

You will need to vote for a new Leader. At least 50% of your Alliance members should support the new candidate. The results (screenshots of the vote) should be sent to our Support Team.
