Problem: Kuaiji Commandery was the initial power base for Xiang Liang and Xiang Yu's rebellion against the Qin Empire which initially succeeded in restoring the kingdom of Chu but eventually fell to the Han.

Problem: In 1983, the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. A coalition of international organizations launched a public pressure campaign to prevent any minerals development in the region, led largely by Greenpeace International, which established its own scientific stationWorld Park Basein the Ross Sea region and conducted annual expeditions to document environmental effects of humans on Antarctica. In 1988, the Convention on the Regulation of Antarctic Mineral Resources (CRAMRA) was adopted. The following year, however, Australia and France announced that they would not ratify the convention, rendering it dead for all intents and purposes. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. The Protocol on Environmental Protection to the Antarctic Treaty (the "Madrid Protocol") was negotiated as other countries followed suit and on 14 January 1998 it entered into force. The Madrid Protocol bans all mining in Antarctica, designating Antarctica a "natural reserve devoted to peace and science".

Problem: In one-party systems, one political party is legally allowed to hold effective power. Although minor parties may sometimes be allowed, they are legally required to accept the leadership of the dominant party. This party may not always be identical to the government, although sometimes positions within the party may in fact be more important than positions within the government. North Korea and China are examples; others can be found in Fascist states, such as Nazi Germany between 1934 and 1945. The one-party system is thus usually equated with dictatorships and tyranny.
When was Nazi Germany in a one-party system?
