Research Paper (undergraduate) from the year 2012 in the subject Law – Miscellaneous, grade: A, , course: LLM INTERNATIONAL LAW, language: English, abstract: The monopoly of the use of force granted to modern States by its citizens is a relatively new phenomenon. Private armies have been operating in European States till the XIX century. The use of mercenaries has been historically a constant phenomenon till almost the end of the XX century, when their activities were criminalized by the international community. Parallel to that phenomenon during the European colonial expansion over all continents, governments had authorized two other forms of similar violence by non-state actors: the corsairs and the colonial merchant companies.
