Edited Version of Alliances Mod, which only allows players to make/break alliances with eachother when their unit is near the opposing leader. Mostly intended to be used with free-for-all (everyone against everyone) maps. The mod's menus can be accessed via rightclick options on leaders (to become allies, select an enemy leader, and choose the 'Send alliance request to this side' option, while if you want to betray your team or leave your alliance, select your leaver, and open the alliances mod menu. There's also a togglable option to send/request gold to/from other players.
