This chapter chronologically traces the Western liberal Constitution’s internationalization from 1919-1960 to establish UNCA’s birth in 1949, rejection in 1960 and revival in 1960. This chapter comprises three sections. Section 1 traces a rise in the Constitution’s internationalization from 1919 to 1960. Section two covers the United Nations’ role from 1949-1952 in assisting Libya, a former Italian colony, adopt the Constitution and emerge independent. UNCA was rejected in 1960 because the right to self-determination morphed into an absolute right for all colonies, whereby they henceforth enjoyed a right to sculpt constitutions of their choice. At this juncture, UNCA serves a limited purpose: to implement decolonization. Section 3 outlines former UN Secretary-General, Dag Hammarskjold’s economic philosophy and his efforts at reviving united nations constitutional assistance to ensure Congo morphs into a market democracy. A discussion of the UN’s constitutional assistance from 1960-64 reveals that its use had nothing to do with perceived local incapacities for governance and how it spawned and guided UN or International territorial administration (e.g., law-making) there.
