Some interesting comments about Rwanda on my last post. I'm not going to touch this particular poverty vs human rights debacle with a barge-pole. In any case, I don't buy the argument at all that autocracy is in general in any way good for development (the data just doesn't support it). But I think you can make a reasonable case that you need to look at the change in governance as much as its absolute level in order to understand its impact upon the economy.
This chart shows trends in Rwandan governance, as measured by the Polity IV project. Positive on the scale is democratic and negative is autocratic. Above 6 gets you full democracy status and minus 6 full autocracy. Kagame came to power around 2000 (update: officially 2000, but effectively 1994?).
