There's a sense where the growth of the "universal international legal framework" is more temporal than geographic, i.e. the application of principles of Westphalian Sovereignty to a wider area of the earth (frequently preceded by the new areas' incorporation into European colonial empires at the expense of indigenous "non-Westphalian" governments). When it came to their European colleagues, 18th-century Spain was perfectly happy to follow international relations principles that we would recognize today. Their conquest of Central and South America was predicated on the Treaty of Tordesillas, in which they and the Portuguese agreed to some lines on a map (with the Pope's help) and went to play "loot the locals".
