For the celebration , here is analysis of his house wheel of his birth chart
The house system in a Birth chart indicates the map of the life of a person . Since we know major events of madara's life , this would an attempt to analyze and verify if this has been true in his life . Placement can play out in many different ways in one's life , I will mostly relate to canon and my assumptions based on it .
This analysis is based on the birth chart calculated by @al-hekima-madara-blog
Madara Birth Chart
Rising - Capricon
The first house is our appearance to the world. Capricon in first house makes a person reserved , stoic , serious , disciplined and calculating .Whenever you look at him the first time, you feel see these qualities in prominently cause his sun and mercury are also present in this first house .
With his Sun and mercury here he appears to be a man of few but meaningful words , also he is very strategic in his plans as we have seen how well he planned the infinite tsukyomi. Now the ruler of his first house Saturn , which is placed in sagittarius would give him heavy physique , buff with wide shoulders, a barrel chest, and thick thighs. But since it's Saturn it will happen gradually .
2nd house - Aquarius
The second house is our upbringing , family lineage . With Aquarius here it means unique (kkekei genkai of uchiha ). This can also be very technical ubringing (Uchiha's fireball jutsu ).
[ This is my personal observation .The signs which have double rulers in this case Aquarius ( ruled by Saturn , then Uranus ) manifests as the traditional ruler themes first and then the modern ruler themes next .]
So upbringing first in early years it would have been about Saturnian themes then transformed into Uranian themes .
2nd house (self worth) , him feeling guilty of not being able to protect his brothers , a restriction (Saturnian theme) then leading the clan to in order to work for the former cause,a revolution (Uranian theme ) ,
With his venus in 2nd house (creativity,) in aquraius (ideas) , could show why he fell in love with the idea creating the village .
3rd house - Pisces
The 3rd house (siblings )being in pisces with his Neptune ( dreams ) could be interpreted as his dream of protecting his siblings . He could have peaceful around siblings , since Neptune in its natural sign .
Izuna through Madara ‘s Birth Chart
3rd house ( Communication) being in pisces (other worldly -Neptune ) , can be seen when talks people are confused , not being able understand what he means , he talks like an old soul ,full of wisdom , (Jupiter ruled pisces ) not just to fill silence but to give meaning to words .
This can be seen in two instances
1)Jupiterian theme/Enlightened Guru -when explains to obito (The famous Wake up to reality speech)
2) Neptinian theme/ Confusing words - when he insulted naruto ,but he didn't understand so obito had to explain it to him .
4th house - Aries
4th house (Family life ) in Aries (Warrior ) , with him being born during warring states , almost all uchihas being shinobi . Family possesing weapons is in fact true . Family Values could be Ariean themes( goal driven , developing power )
The ruler being mars is in 8h (things that we hide)These things were hidden from the outsiders ,(people know about Uchiha's powers but speak in hidden ways about it ). The way of shinobi could be seen from this .
5th house - Taurus
5th house represents ( creativity , pleasure and also children ) with Taurus (building things , creativity , guarding, stubbornness) here , we can see him enjoying the planning of village when he and hashirama were children , inorder to protect other children including their brothers .
We also see him running towards to the little girl ( hiruzen' wife ) when she falls to save her . It also explains why he was so stubborn on building the village his way .
6th house - Gemini
6th house represents ( Daily chores , routine, also enemies ) in Gemini ( Quick fast , dual ) and top of this there is Uranus (Invention, uniqueness, ideas )here .
We see him practicing daily with hashirama who from the enemy clan ( deep down they both knew it)
We see him sometime joking with him both also training seriously like shinobis , with Uranus here he was called a genius in his day to day life for his victories against adult senjus .
7th house - Cancer
7th house represents (partnership , shadow self ) , in cancer ( emotions, family ) with moon being its ruler , increases it more , but outsiders don't see it as he his shadow traits ( hidden kindness) .
One can see him and izuna ( family ) leading the clan together as equals . He trusts his family for work , seen when he chooses obito .
He even choose to work with Hashirama cause he was caring to his own family , and that's why he describes Madara kind cause that's the side he saw in their partnership.
8th house - Leo
8th house represents ( taxes ,sudden events , crisis, even death , things we hide and bury, occult ) in leo (creativity , stage , aesthetic ) with his mars and jupiter conjunction .He was in the underground tunnels (8h) while acting on his plan ( mars) Now we see him almost staging (how actors die in a scene but bot really ) his death , in the VoTE battle .
8h is also manipulation he was manipulated by zetsu , and then he manipulated obito for the Action (Mars ) on the plan .His actions (mars ) save obito from dying (crisis situation) .His knowledge( jupiter )in occult ( the sage six paths lore ,him summoning the gedo statue ) was expanded .
9th house - Virgo
9th house represents (higher education , belief system , philosophy ) and Virgo (analysis , cerebral , service ) .The ruler being mercury in capicon lead him to be cynical and skeptical .This was seen , when he analysed and found fault in hashrima's belief that village is above the individuals , stated his priorities are backwards during VoTE battle .Madara believed that he was giving a service to humanity by putting them in an infinite tsukyomi so planned every step in detail by studying the stone tablet for this belief .
10th house- Libra
10h represents ( Public image , business , structure , government ) in libra ( partnership , balance, diplomacy) . So no wonder madara became a leader of the clan , but what lead to his downfall. The ruler of libra ( venus) is in aquarius , although being the leader , he would have been very aloof and got the image of cold , uncaring. So izuna being his partner to lead may have dealt with people majorly . Also it being in 2nd house (self, possessions) he took izuna who was closest to him abandoning his other clansmen when they were about to lose to enemy.
11th house -Scorpio
11th house represents ( ideas ,community , gains , friends) and Scorpio ( obsessions , passion ,intensity also transformations ) with pluto here rulling it gets intense
This is seen throughout his life , he didn't have many friends but he had one , hashirama .This explains his obsession with his friend ,with pluto it only got intense over the years so much that he waited to fight the real hashirama during the 4th war and was even hurt when hashirama rejected his offer .It is almost poetic he was backstabbed by his only friend . His transformation ( sage mode ) is seen by the shinobis ( community )
12th house - Sagittarius
12th house ( other worldly things , isolation , wisdom ) Sagittarius here almost feels at home alongside Saturn . Saturn being his chart ruler he spent most of the time in isolation (12th h)in the cave and genjutsu . Putting himself in genjustu day after day , for years this is patience and hard work (saturn) while gaining knowledge (sagittarius).
