Your definitely somewhat right but it's a bit more complex than that. France has been a world power for centuries and while not as old as Iraq there is a reason people visit. In scandavia's Case the sagas are really intresting and are masterpieces of world literature sudan doesn't really have an equivalent to this. Also the vikings have been a fascination in europe for centuries because they were way more influential than people today who don't know the history realize. Russia was founded by vikings. The descends of the vikings who became the norms also conquered England and ruled it for centuries. They also fought across Europe as mercenaries and traded all over. In that sense they were more influential in shaping world history than the anicnet sudanese kingdoms.
To be honest your ‘world history’ is basically Europe, which is fair but this is the same Europe that was barely mentioned in, what was historically that continent’s most important book, the Bible, while ancient Sudan is referenced multiple times within. European history looks so much grander today precisely because in the last couple of centuries they surpassed their ancestors. If Sudan today was a multi-trillion dollar economic power, with military bases across Africa and a globally popular soft power industry, the histories of Kerma, Kush, Meroe, the Three Kingdoms of Nubia, the Mahdist State, etc would all be illuminated in cinematic theatres and tv-screens, while millions of tourists would visit their ancient sites.
Another good example of this today would be the two Koreas, one is an advanced modern power, with a global economic and cultural reach, which is why Korean history movies and tv-shows are so popular around the world, and why nobody is making threads about what Koreans contributed to history. The other country (North Korea) is a poor nuclear power state with the same economy as a recovering Somalia. If the South was anything like North Korea, their overall history would be significantly diminished in terms of people’s interest compared to what it is today as a result of South Korea’s status.
Which is why Somalis, especially the leaders, need to focus on pushing Somalia to a new level economically, because everything else would naturally fall into place, be it global perception, reputation, importance or acknowledgement.
