What was the Berlin Conference of 1885-1886 notable for establishing?

The Berlin Conference of 1885-1886 was notable for establishing the Rules of Engagement for the European colonization of Africa. The rules were designed to prevent conflict between the European powers as they carved up the continent, and included provisions such as the requirement for effective occupation of claimed territories and the recognition of the Congo Free State as a neutral territory. The conference also established the borders of the modern African states, which have remained largely unchanged to this day.
