Look at the nations where "Democracy" is mostly known for as the keystone of their governments. England and the US.
Now the modern tradition started in England, of that I do not deny. But it was a long, slow, drawn-out process. Going over the centuries from the Divine RIght of Kings, through the Magna Carta. But this led to more advances, including the Bill of RIghts, and eventually the Parliament we all know of today.
Most do not even realize that in the original Parlaiment, the King ordered the Barons and other noblemen to appear before him, and he would dictate to them what he wanted. But a few centuries later, the rolls were reversed. After the Magna Carta, the King now had to answer to at least some degree to the Parliament. Then a century after that, the House of Commons gave the unentitled people a say in the Government.
The US followed much of the same system in their government. With an Executive (President), and a 2 house Congress (Senate and House of Representatives). It was not all that different then the Monarch - House of Lords - House of Commons system they had recently seperated from. We did much the same when we set up "Democracy" in Japan after WWII. We left the Monarch in place, putting in a Constitutional form of government with a body that was answerable to the people as oversight.
This is why I think the British model is a good one to follow. Leave in place a figurehead that the people can rally around and give them continuity, as their elected bodies grow into their new positions, and realize that Democracy does not mean "mob rule". Trying to thrust upon a people almost 1,000 years of political evolution in a single shot simply does not work. It failed in Germany after WWII, it failed almost everywhere it was ever tried unless there was already a foundation in place.
