Bartertown is a fictional settlement featured in the film Mad Max Beyond Thunderdome. It serves as a trading hub in a post-apocalyptic world, where goods and services are exchanged without the use of money. The community is built on the principles of barter, allowing people to trade items they possess for things they need. The town is governed by a unique system, with a leader known as Aunty Entity, who maintains order and oversees trade. Bartertown is also famous for its arena, where conflicts are resolved through combat, notably in the Thunderdome, a cage-like structure where fighters engage in duels.
