Alongside domestic developments relating to conflict of laws, the nineteenth century also saw the beginnings of substantial international collaboration in the field. The first international meeting on the topic took place in Lima in 1887 and 1888; delegates from five South American countries attended, but failed to produce an enforceable agreement. The first major multilateral agreements on the topic of conflict of laws arose from the First South American Congress of Private International Law, which was held in Montevideo from August 1888 to February 1889. The seven South American nations represented at the Montevideo conference agreed on eight treaties, which broadly adopted the ideas of Friedrich Carl von Savigny, determining applicable law on the basis of four types of factual relations (domicile, location of object, location of transaction, location of court).
