The Assembly of the Republic of Louisiana was noteworthy for the simplicity of its structure. Unlike the U.S. Congress, it was not a compromise between popular and provincial representation. Nor was it a compromise between democracy and aristocracy, unlike the British Parliament. It was designed by men who were not afraid of a government that could (at least in theory) engage in quick and decisive action when necessary. That, after all, was how they had come to secede in the first place.
The Assembly was comprised of one chamber. Elections were held every three years on the first Saturday in August. Each parish sent at least one representative to the Assembly. If it had between 1,000 and 2,000 residents, it had two representatives. Between 2,000 and 3,000 residents meant three representatives. And so on. Although this might seem to weight the Assembly in favor of the more heavily populated Orleans Parish, it also gave greater influence to the votes of large slaveholders, whose slaves could not vote but were nonetheless counted in the census.
The first order of business of each new Assembly was to choose a president and vice-president. In the case of the 1815-1818 session, these were Jacques Villeré and Jean Noel Destréhan. No one could serve two consecutive terms in either office — indeed, a president or vice-president who had completed one term was obliged to wait two election cycles before having his name put forward again. This was intended to reduce the danger of a single individual dominating the government.
It had, however, a (possibly) unintended effect. Presidents were, with the consent of the Assembly, allowed to appoint ministers who could serve until they died or were replaced. The intention was to allow the Assembly to benefit at all times from the greatest expertise available in a given field. However, it was soon noted that there was no requirement for a minister to be an Assemblyman — or even a citizen of the Republic. The result was the slow growth of a permanent cabinet of “expert advisors” sent from London…
