who is often regarded as the father of international law
International law The modern study of international law starts in the early 19th century, but its origins go back at least to the 16th century, and Alberico Gentili, Francisco de Vitoria and Hugo Grotius, the "fathers of international law."[9] Several legal systems developed in Europe, including the codified systems of continental European states and English common law, based on decisions by judges and not by written codes. Other areas developed differing legal systems, with the Chinese legal tradition dating back more than four thousand years, although at the end of the 19th century, there was still no written code for civil proceedings.[10] Some doubt the effectiveness of international law, as they see the implementation of international law as a policy option among others to tackle global dilemmas.[11] They say that international law must be evaluated with other, possibly more effective, international law options.[12]
Slavery in international law The concept has its roots in the 1807 Abolition of Slavery Act of Great Britain. Many academics in the field perceive this as the beginning of the end of the traditional form of slavery: chattel slavery. In the 19th century, Britain controlled the majority of the world through its colonies. Consequently, in passing this law to abolish slavery, the British Parliament abolished slavery in the vast majority of its colonies.
