Lets not forget that the First Hokage supposedly used his Kekkei Genkai to help grow the huge forest around Konoha.  The ability to more or less terraform an area was a massive boost to the Land of Fire.

They don't make shadow clones in the academy, it's just clones that are entirely illusions.

Tobirama is the greatest and most important Hokage in the entirety of the Konoha's history. His ideas to have the Senju marry outside of the clan, the police force, the anbu, the ninja academy, the chuunin exams, his eventual trust of the Uchiha and his R&D work make him the most effective hokage in history. Plus my guy was a total badass

12:08 The academy clone jutsu is actually separate from the Shadow Clone Jutsu. Naruto failed the exam because the clone jutsu he did make was pitiful, then learned the Shadow Clone Jutsu from the Forbidden Scroll which allowed him to make physical copies of himself unlike the academy clone which was not physical, an illusion.

I'm a Tobirama Stan for LIFE.  You're one of the only people who recognizes how great and important he was.  He's severely underrated and I think it's on purpose so he doesn't take away from Hashirama.

Fun fact the thrid mizukage was probably the oldest kage living until his death. He was an adult during the first kage summit and was the kage during the third shinobi war because we know the mist put isobu into rin confirming yagura wasn't its host yet.

Because the 2 most powerful clans worked together. Most concentrated sage of 6paths chakra

I just realized that kurama is stronger than all the other tailed beasts combined, that means that the difference between 9 tails and 10 tails is 49% stronger at most

12:10 'Think of how you pass academy. You have to create a Shadow Clone' actually, shadow Clone is a Chunin level technique because the Chakra consumption of cutting your reserves in half is too dangerous. I think for Genin it's a kinjutsu. (Actually, since it was in the Forbidden scroll, it might've just been a straight up kinjutsu that people might've already known)

The one to pass the academy is the genjutsu Clone technique that just makes a fake double with no substance

Dude you r the best informational speaker I swear, you have a way of explaining things in a way that keeps me hooked. Thank you for all your hard work!

Glad you pointed out Tsunade and Ino's contribution for the village, Past and Present respectively ⭐

If one more person calls the clone jutsu the shadow clone jutsu I’m going to flip normal clones aren’t physical clones shadow clones are that is why we only see a few people use shadow clones. The jutsu they learn at the academy is the clone jutsu not shadow clone jutsu

I think because they had the Senju and Uchiha, the strongest clans on earth, make an alliance, many other powerful clans also came in and decided to join the alliance with the goal of becoming stronger by joinging the strongest. Because of this you basically have several of the strongest clans joining together to create an even stronger village. Plus because of this you have all these kekkei genkei and just powerful bloodlines all of which aid Konoha, for example the Inoichi clan’s ability to communicate and relay orders (that came in handy during the fourth war) or the Uchihas Sharingan which can instantly replicate any non kekekei genkei meaning the Uchiha just get stronger when they’re fight a strong opponent. Plus on top of that the Uchiha are all prodigies so even without the Sharingan you still have a skilled Ninja.

11:00 Tobirama is the most underrated Hokage

I was one of the few people who never hated Tobirama. I saw all these memes about him hating the uchiha...why would he have an uchiha on his personal force. He literally invented three jutsu's that was the base of shippuden. No other hokage has achieved more than what he achieved during this time. He was the greatest leader. Another super underrated hokage is Kakashi. He governed konoha for 10 years , maintaining peace, establishing stable commerce , building infrastructure, modernizing konoha. He literally transformed konoha into a modern day city. Respect to him as well.

Short Answer: Plot
Long Answer: Plot

My guess as to why the other villages don't adapt the idea of 1 medic per squad is because they just don't have the medic strength/ability to go around, so they more so go the field hospital route of keeping a team(s) in strategic locations and having the wounded brought to them. Especially the hidden sand since they don't have enough human shinobi and utilize their puppets to bolster their strength in general.

On top of everything you listed, the Leaf got Ashura and Indra who guaranteed two shinobi with massive potential.

@12:20 you have to make a clone not a shadow clone to pass the academy
