Many third world countries tend to experience political instability from time to time. Close examination of the situations in these countries often reveals that there are certain core things that fuel the said political instability.
In some cases, the political instability in third world countries turns out to be a result of poor governance. The poor governance leads to poverty, which in turn leads to political uprisings. At other times, the poor governance leads to breakdown of the state organs that are supposed to intervene in case of political instability.
In some other cases, the political instability in third world countries turns out to be as a result of interference by developed countries. The developed countries interfere (using underhand means, of course) in order to ensure that the third world countries become unstable, so that they can exploit their resources or otherwise use them as platforms to achieve other strategic objectives.
In yet other cases, the political instability in third world countries turns out to be as a result of historical factors. This is where, for instance, you find situations where the colonialists (most third world countries were colonized) set the borders in such a manner that they ended up grouping together communities that simply can’t coexist.
