scholars focus on the upper-class domination of the leadership and possible control of the assembly and see an oligarchy or an aristocracy. Despite the assembly's obvious power, it has not yet been established whether the composition and participation were truly popular. This is reflected in the Arthashastra, an ancient handbook for monarchs on how to rule efficiently. It contains a chapter on how to deal with the s, which includes injunctions on manipulating the noble leaders, yet it does not mention how to influence the mass of the citizens, indicating that the "" are more of an aristocratic rule, or oligarchic republic, than "democracy". Icelandic Commonwealth The Icelandic Commonwealth was established in 930 CE by refugees from Norway who had fled the unification of that country under King Harald Fairhair. The Commonwealth consisted of a number of clans run by chieftains, and the Althing was a combination of parliament and supreme court where disputes appealed from lower courts were settled, laws were decided, and decisions of national importance were taken. One such example was the Christianisation of Iceland in 1000, where the Althing decreed that all Icelanders must be baptized into Christianity, and forbade celebration of pagan rituals. Contrary to most states, the Icelandic Commonwealth had no official leader. In the early 13th century, the Age of the Sturlungs, the Commonwealth began to suffer from long conflicts between warring clans. This, combined with pressure from the Norwegian king Haakon IV for the Icelanders to rejoin the Norwegian "family", led the Icelandic chieftains to accept Haakon IV as king by the signing of the Gamli sáttmáli ("Old Covenant") in 1262. This effectively brought the Commonwealth to an end. The Althing, however, is still Iceland's parliament, almost 800 years later. Mercantile republics In Europe new republics appeared in the late Middle Ages when a number of small states embraced republican systems of government. These were generally small, but wealthy, trading states, like the Mediterranean maritime republics and the Hanseatic League, in which the merchant class had risen to prominence. Knud Haakonssen has noted that, by the Renaissance, Europe was divided with those states controlled by a landed elite being monarchies and those controlled by a commercial elite being republics. Italy was the most densely populated area of Europe, and also one with the weakest central government. Many of the towns thus gained considerable independence and adopted commune forms of government.
