tzaddiq:
In Torah we have theocracy, rule by G-d, not rule by a government. A “king” who goes against Torah can be overthrown.
Most Jewish commmunities throughout history were dominated by a coalition of the leading Talmidei Hachamim and the leading citizens (a typical method of election was to choose be at random and ask them to pick the leaders – since a leader in Jewish tradition is responsible for paying the community’s financial needs this was alway a very rich person – in fact in some communities they had a “CEO” with the title “Parnas”).
