Sasuke Uchiha's BackGround

SASUKE UCHIHA'S BACKGROUND -

Being the youngest
son of Konoha Military Police Force captain and Uchiha
clan head Fugaku Uchiha and his wife Mikoto and named after the father of the Third Hokage, Sasuke grew up in the
shadow of his older brother, Itachi Uchiha. Itachi was an acknowledged prodigy who was viewed by the
Uchiha clan as a genius, and whose work would
further strengthen the bonds between the village
and the clan. Sasuke's father in particular took an
active interest in Itachi. Itachi, on the other hand,
was rather ambivalent and full of oddly conflicting undercurrents, acknowledging Sasuke by taking
interest in his progress as a ninja when even their
father did not, but spending little quality time with
Sasuke. Even after Sasuke enrolled in the Ninja Academy, he was still unable to escape Itachi's shadow. Despite consistently scoring at the top of
every class, Sasuke failed to receive any
recognition from his father, who defined Sasuke's
success only in terms of his older brother. Itachi
acknowledged the rivalry Sasuke felt, telling him,
"We are brothers. I am the wall you must climb over, so you and I will continue to exist together."

The relationship between Itachi and his father
deteriorated further after Itachi was questioned by
other members of the Uchiha clan regarding the
apparent suicide of his best friend, Shisui. As Itachi's behaviour became increasingly bizarre,
Sasuke's father began spending more time with
Sasuke, and began teaching him the Great Fireball Technique, a common family jutsu seen as a sign of coming of age in the Uchiha clan. When Sasuke
first tried to perform the jutsu, he only had a small
flame come out and after that, some smoke. His
father said that Itachi was able to do it on his first
try at Sasuke's age, which disappointed him. Later,
with one week of training, Sasuke (age 7 at the time) performed the jutsu in front of his father,
proving himself a genius as well in his own right
and finally receiving his father's recognition.
Sasuke's father told him that he could now proudly
wear the clan's emblem on his back. Following this,
Sasuke also received a stern warning not to follow in Itachi's footsteps any further, surprising him as
before, he was told to be like him; and his father
showing he was proud of Sasuke for the first time
the same way as he used to with Itachi.

On one fateful
night, Itachi slayed every member of
the Uchiha clan,
sparing only
Sasuke, saying that
he was not even
worth killing. In addition, Itachi told
him, "You've
always wanted to surpass me. That's why I'm
going to let you live... if you wish to kill me, then
hate me, despise me... and by all means flee, cling to
your wretched life." Itachi also revealed to Sasuke where the secret meeting place of the Uchiha was hidden, and suggested that Sasuke go there to
learn what the true history and purpose of the Sharingan was. He told him that "to awaken the Mangekyō Sharingan," he "had to kill the person he was closest to", and that "when we battle, we
should have the same eyes". Sasuke thought he
had fainted after this, but later remembered that he
had managed to stand back up, awaken his
Sharingan, and pursued Itachi. Upon reaching
Itachi, he used knives to knock off his forehead protector. Itachi was seen shedding a tear as he was picking up the forehead protector. He then
proceeded to incapacitate Sasuke, who awoke in
the hospital remembering only that which Itachi
wanted him to.
