A similar effect that the fall of Gaddafi's rule and of the Mongol and Macedonian empires' falls was:
An economic depression after the fall, all of the three falls saw the land's economy receding. As Libya's government fall the capability of the country to trade decreased greatly, as it became harder and harder to move oil from the petroleum-rich portion, southern Libya, to the coastal region; where the oil could be brought to the costumers (mainly European countries like Italy). In a few words the internal trade of goods was halted, this was worsen by the complete stagnation of the country's tourism. Something similar happened when the Mongol and Macedonian empires fell. By having a more united country trade is naturally aided, as there are fewer restrictions and tariffs on the goods which enter and exit the nation. After a few decades of the Mongolian and Macedonian fall the economy instead recovered and advanced to levels never seen before, again this was only possible because of these two empires: even if they fell they enabled connections between far away people.
These two strong economic periods, Pax Mongolica and The Hellenization, were only made possible by these two great empires. As not enough time has passed from the fall of Gaddafi's regime it is impossible to state if it will have a similar effect, all we can do is wait and observe. But from what I know if there will be an economic revival in Libya its scale will be more minor, as it will involve just Libya. Whilst the other two economic revivals included many different and diverse lands. It is very complicated to predict what will happen to Libya, it might be that it will unite or it could become many different states. Whatever will happen I strongly believe that as the situation will cool down the country will see a major economic revival, mainly because the country has one of the biggest oil reserves in the country and if they are used in the correct manner Libya could become once again Africa's most economically developed country.
The reason behind why these three countries fell was very different. All had a sole nondemocratic ruler, in Macedonia's and Mongolia's case the emperor died and then as there was no clear heir the empire soon crumbled. On the other hand Gaddafi died not before the fall of his government but after. The population in the Mongolia and Macedonian did not have major effects on the fall of the empire, only the few who had power affected the life of the government. Instead in the Libyan revolution the people were the ones who caused the fall. This was due to how the people rebelled as they felt oppressed by the tyranny of their ruler.
Partially similarly the country of Libya was not as united as other countries, this was due to the fact that the country has many different ethnic groups, the major one is the Arab one in the north. It is the major one as it inhabits the portion of Libya which is capable of sustaining more people, the north. The southern portion instead is inhabited mainly by Touareg and Tebou people, which in history they have been oppressed as they were nomadic tribes. These Nomadic tribes were less united and less organized as the northern people; thus the people in the north always had an advantage; mainly as they inhabited coastal Libya which could sustain a higher population. Mongolia and Macedonia also had many different ethnic groups, but their number and difference was greater as the empire was of larger side. Language-wise it is similar, as in the north the common language is Libyan Arabic but in the south it is unspoken and other berber languages are the common ones. In Macedonia and Mongolia a common language developed, but this took time; and not enough time passed to see all the effects and make a perfect comparison.
