the Pada legend the year 1019 - 1042 East Java kingdoms diperintah by a Putera from results of the marriage between the Mahandradata Daughter and Udayana (a Balinese Prince) that was named Airlangga, when the Airlangga government, the country's peaceful situation, the security was guaranteed, and the country experienced the fast progress. Because the king Airlangga had 2 sons, then at the end really his government he gaze at must divide the kingdom into two parts to be handed over to Putra's two him, so that dikemudian the day did not happen the struggle for the throne. the distribution happened in the year 1042, that is becoming the Daha kingdom (Kediri) and the Jenggala Kingdom. The Jenggala kingdom that stood in the year 1024 were located in the area of the Brantas delta, that is covering the north coast all of them, therefore controlled ports and the estuary of the big river, whereas his capital was around the Gedangan Subdistrict now. It is another matter with the Kediri Kingdom, did not have the port one also so as although results of agriculture in Kediri were very big and the tribute flowed with very big, all of them all that could not be traded in because the Kediri kingdom was closed from sea as the trade road at that time.
So in the area of the Brantas Delta beforehand in around between the year 1042 - 1045/1960 once had stood suata the kingdom that is the Jenggala kingdom. That could be proven that when the Sidoarjo Regency his government's composition was divided into several kawedanan (the district), evidently the names kawedanan this still used the names that were used in the Jenggala royal period, for example: Jenggala I,Jenggala Ii, Rawapulo I, Rawapulo Ii, et cetera. These names were lost in approximately in 1902.
originally, to be precise during 1851 the Sidoarjo area was named Sidokare, part of the Surabaya regency. The Sidokare area was led by a person patih was named R. Ng. Djojohardjo, lived in the village of Pucang Anom that dibatu by a district chief that is Good Ranuwiryo that resided in the Pangabahan village.

In 1859 same, by being based on the Instruction on the Dutch East Indies Government of No. 10/1859 on May 28 1859 Staatsblad. 1859 names of the Sidokare Regency were replaced with the Sidoarjo Regency. Therefore was able to be said that officially the formation of the Area of the Sidoarjo Regency was tangal on May 28 1859 and as Regent I was R.Notopuro (R.T.P Tjokronegoro) Originally the Regency house in the area of the Pandean village, afterwards because something then Regent Tjokronegoro I was moved to the Pucang Village (Wates). Here he built the Jamik mosque that was this current (the Agung mosque), but still in the form of that was very simple, while on the west was made the Pendem cemetery (Beautiful). During 1862, he died after suffered was sick, and was buried in the Pendem cemetery (Beautiful). As his substitute during 1863 was appointed by the older brother alnarhum as Sidoarjo Regent, that is Regent R.T.A.A Tjokronegoro Ii (Kanjeng Djimat Djokomono), pindahan from Lamongan. In Regent's government's period of Tjokronegoro Ii this the development - the development received attention was very big in part, continued the development of the Jamik mosque that still was very simple, the improvement against the Pendem cemetery, by that was developed also the Magersari Village one West Kabupaten, that afterwards was placed there Madurese. During 1883 Regent Tjokronegoro got the pension, that not long afterwards in his same year died, was buried in the cemetery of Botoputih Surabaya. As his substitute was appointed by R.P Sumodiredjo pindahan from Tulungagung but only went 3 months because of dying in the same year and being buried in the Pendem cemetery. Further in tahun1883 that was appointed by R.A.A.T. Tjondronegoro I this was able to be recorded as follows: Dalam Bidang Pembangunan o the Finishing of the Jamik mosque that was built by the Regents previous that is widened and beautified with the marble fitting. This development was begun the Jum'at Kliwon day the date 26 Muharrom 1313 H, coincided with the Wawu year 1825 and on July 19 1895. For the cemetery of the Regents as well as his family, the village chiefs and all ahlul the mosque was maintained in the yard of the Jamik mosque (like that is witnessed by us now) * Dalam Bidang pemerintahan o the Pemerintahan Composition (Hierarchie) at that time in the Sidoarjo Regency was divided into 6 Kawedanan (the District) that is: 1. Kawedanan Gedangan 2. Kawedanan Sidoarjo 3. Kawedanan Krian 4. Kawedanan the Jenggolo Garden 5. Kawedanan Porong Jenggolo 6. Kawedanan Bulang These Kawedanan names evidently still used the names when the Jenggal Kingdom beforehand. Really Pedudukan Japan (on March 8 1942 - on August 15 1945) As also areas in Indonesia, from March 8 1942 the area of the Brantas Delta was supervised by the authority of the Government of the Japanese Military.

As being recorded on August 15 1945, Japan surrendered to the Ally, at that time was time that as well as possible for the Indonesian Nation to run away from the colonisation shackle, everywhere in the Republic of Indonesia area was formed various bodies or the association that were national. At that time that had the power in the area of the Brantas Delta to be Kaigun (the Sea of Japan troops) that willingly handed over his weapon to our young men. The armed bodies began to be formed by the name of B.K.R and P.T.K.R. Diantara these armed bodies that most had the power didaerah we at that time were P.T.K.R. was supervised headed by Mayor Sabarudin. Murders were undertaken against them who were suspected as the enemy's spy. Because of his action that melampui the limit then by the management side that tertingggi was deemed necessary to disarm the P.T.K.R. weapon available was supervised headed by this Sabarudin. Finally the Sabarudin authority dkk. could be paralysed.
the beginning in March the Netherlands began to be active with his efforts to occupy again our area. Dutch time occupied Gedangan, Pemerintah gaze at must move the centre of the Government of the Sidoarjo Regency to Porong. But still had officials who were assigned to continue to live in the Sidoarjo city as the representative from the Government. Afterwards in the Temple in the form of the Gabungan Post as the defence. At that time derah Dungus (the Sukodono Subdistrict) became the area of the struggle with the Netherlands. On December 24 1946, the Netherlands began to attack the Sidoarjo city with the attack was undertaken from the Tulangan route. Then on that day also the Sidoarjo Area fell ketangan the Netherlands. The government of the Sidoarjo Regency was moved again to the Jombang area.

Not long after the re-surrender of the Sovereignty to the Republic of Indonesia Government, was based on regulations of No. 22/1948, R. Soeriadi Kertosoeprojo was appointed to the Regent/the District Head in the Sidoarjo Regency. Many difficulties that were dealt with by the Government of the Sidoarjo Regency that was new. Particularly because the Area of the Brantas Delta was the area of the connector between the Surabaya city and the area pedalamanan. As being learnt by us the Surabaya city was including the city that was biggest in Asian Tengara, so as to not escape from intaian foreign countries that wanted to spread his ideology didaerah Indonesia. Because of that the Sidoarjo area also faced all the infiltration sorts, especially from the side that did not like the Republic of Indonesia existence.
Kekacuauan- kekacuauan began to emerge again in areas. Kekacuauan- kekacuauan that especially being caused from the follower's Dutch efforts that did not want to submit was supervised by the Republic of Indonesia Government. Around the agitators was the agitator who was led by the former Tromposari village Village Head (the Jabon Subdistrict) that is the Sidjono Priest alias the Owner.
