Kingdom was a Hindu kingdom located on the western part of
Java from 669 to around 1579, covering areas of present-day
Banten, Jakarta, West Java, and the western part of Central
Java. According to primary historical records, the Bujangga
Manik manuscript the eastern border of the Sunda Kingdom is
Pamali River (Ci Pamali, present day Brebes River) and
Serayu River (Ci Sarayu) in Central Java. Most of the
accounts of Sunda Kingdom came from the primary historical
records dated from the 16th century.
There is continuous
knowledge about the kingdom among Sundanese people that has
been kept alive through Sundanese Pantun oral tradition, the
chant of poetic verses mostly tells the story of the golden
era of Sunda Pajajaran and the legend of King Siliwangi, the
popular king of Sunda.
Most of the account and records of Sunda kingdom came
from ancient manuscripts dated from later period, such as
Wangsakerta, Carita Parahyangan, Kidung Sunda, Bujangga
Manik, and Pustaka Rajyarajya i Bhumi Nusantara. Several
stone inscriptions also mentioned the kingdom, such as
Jayabupati, Kawali, and Batutulis.
According to Wangsakerta manuscript, king Tarusbawa from
Sunda Sambawa, a vasal kingdom of Tarumanagara, had
succeeded his father in-law as the 13th king of Tarumanagara.
At the same time, Tarumanagara's prestige and power had been
declining, likely due to the series of invasions from
Srivijaya. Wishing to restore the glory of King Purnawarman
that reigned from Purasaba (capital city) of Sundapura, in
670 AD he changed the name of Tarumanagara to Sunda kingdom.
This event confirmed by a Chinese source that mentioned the
last time Tarumanaga sent their envoy was in 669 AD.
Tarusbawa did send his emissary to the Chinese Emperor at
the time to informed his ascension to the throne in 669 AD.
He was crowned on the date 9 on full moon on Jesta month in
591 Saka, or corresponds to 18 May 669 AD.  Separation
of Galuh and Sunda Kingdom Citarum River separates Sunda and
According to the Wangsakerta manuscript, the
establishment of the Sunda Kingdom was used as an excuse by
Wretikandayun, the lord of Galuh, another former vasal
kingdom of Tarumanagara to break eastern Taruma apart from
Tarusbawa's Sunda. Since the crown prince of Galuh is the
son in-law of Queen Sima of Kalingga, a Hindu kingdom in
central Java, Wretikandayun with the support from Kalingga
demands that the remnant of what was known as Tarumanagara's
territory should be divided into two kingdoms. Finding
himself in an unfortunate position and unwilling to risk a
civil war, King Tarusbawa granted Wretikandayun's demand. In
670 AD Tarumanagara was divided into two kingdoms: the Sunda
Kingdom in the west, and the Galuh Kingdom the east,
separated by the Tarum (Citarum) River.  Sanna and
Tarusbawa is the good friend of Bratasena or Sena (709 -
716), the third king of Galuh. He also known as Sanna, as
mentioned in Canggal inscription (732 AD), uncle of Sanjaya.
This friendship encourage Tarusbawa to took Sanjaya as his
son in-law. Bratasenawa (Sanna or Sena) is surpassed from
Galuh throne by Purbasora in 716. Purbasora is the grandson
of Wretikandayun from his eldest son, Batara Danghyang Guru
Sempakwaja, the founder of Galunggung kingdom. On the other
hand Sena is also grandson of Wretikandayun from his
youngest son, Mandiminyak, the second king of Galuh (702-709
Actually Purbasora and Sena are brothers because of the
affair between Mandiminyak and Sempakwaja's wife. Sempakwaja
can not succeeded his father because he is toothless, a
shameful physical handicap considered unsuitable to be king
at that time. That's why his younger brother has inherited
the Galuh throne from Wretikandayun. However, the son of
Sempakwaja still felt deserved to the throne of Galuh.
Moreover King Sena has doubtful scandalous origin that
fueled Purbasora rebellion and determination to took Galuh
throne from Sena.
With the aid of his father in-law, King Indraprahasta,
from a kingdom near present day Cirebon, Purbasora launch
his coup on Galuh throne. Defeated Sena flee to Kalingga,
the kingdom of his wife's grandmother, Queen Shima. 
Reunification of Sunda and Galuh
Sunda Kingdom and Galuh Kingdom coexisted under a strange
and complex relationship. At times the two kingdoms united
as the Sunda kingdom under the same king, at others they
separated with different kings. They would finally unify as
the Sunda kingdom under the same king.
Since the crown prince of Sunda died before King
Tarusbawa, Princess Tejakencana (the daughter of crown
prince) was hailed as heiress of Sunda. She married to
Rakeyan Jamri, who was a son of Bratasenawa (the third king
of Galuh kingdom and a son of Wretikandayun) and princess
Sanaha (from Kalingga). In 723 Jamri surpassed Tarusbawa to
be the second king of Sunda. As the lord of Sunda he was
known as Prabu Harisdarma and when he acquired the throne of
Galuh he was known as Sanjaya.
Although the kingdom of Sunda left little archaeological
remains, the memory about the kingdom was kept alive within
the culture of Sundanese people through Pantun oral
tradition, the chant of poetic verses. Sunda kingdom is
revered as the prosperous and glorious golden age. The
historical identity and the source of pride for Sundanese
people, the same as Majapahit for Javanese people. The
pantun that mentioned Sunda Kingdom (popularly known as
Pakuan or Pajajaran).
