Dutugamunu, also spelled as Dutthagamani, also  referred to as  Dutthagamani Abhaya "fearless Gamini", was a Sinhalese king of  Sri Lanka  who reigned from 161 BC to 137 BC.  he's  renowned for defeating and overthrowing Elara, the usurping Tamil prince from the Chola Kingdom, who had invaded  the dominion  of Rajarata in 205 BC. Dutugamunu also expanded and beautified  the town  of Anuradhapura and projected  the facility  of his native Rajarata region across the island of  Sri Lanka .
Due to his significance  together  of  the foremost 
 potent symbols of Sinhalese historical power, Dutugamunu's story is 
swathed in myth and legend. However, many aspects of the accounts of his
 life  are  verified by contemporary inscriptions,  and therefore the  basic account of his life  is usually  accepted as accurate.
Etymology
The
 Mahavamsa describes how as a youth he mocked his father Kavantissa, 
king of Ruhuna, for refusing to wage war against the powerful invading 
Elara, the Chola king of Anuradhapura, who usurped the throne by killing
 the native kings. The prince stated that "If [his] father was  a person  he  wouldn't  speak thus" and sent him  a bit  of women's jewellery. The resulting fury of the king caused many of his friends  to escape  to Malaya region  and therefore the  prince himself being dubbed Dutthagamani, meaning "disobedient". After his death, he was  mentioned  as Dharma Gamini ("righteous Gamini"), but  it's  as Duttha Gamini or Dutugemunu that  he's  known to posterity. 
Ancestry and family
The Mahavamsa constitutes  the main  source on Dutugemunu's reign and dedicates some six chapters (out of 35) to his tale. In chapter 22  he's  described as being descended from  the traditional   royalty 
 of Rajarata through Devanampiyatissa's brother Mahanaga. At the time of
 his birth Dutugemunu's father was Kavantissa, king of Ruhuna,  alittle  kingdom in south-east  Sri Lanka  outside of the influence of Rajarata  within the  north; the border between  the 2  polities was the Mahaganga, or 'Great River', possibly  the fashionable  Menik Ganga. Kavantissa is portrayed  within the  Mahamvamsa as 'devoutly believing  within the  three gems,  he provided the brotherhood continually with...needful things'.
Dutugemunu's
 mother was Viharamahadevi, daughter of Tissa, king of Kalyani. Legend 
has it that as punishment for Tissa slaying a Buddhist monk, Kalyani had
 been subject to a series of deluges from  the ocean . To placate it Tissa placed his daughter Devi  during a  golden boat with the words 'A King's Daughter' written on the side, and set her  bent  sea. Miraculously the princess washed ashore, alive and well, in Ruhuna, and married Kavantissa.

| Stachu of Viharamaha Deevi (Mother of King Dutugamunu) | 
During her pregnancy with Dutugemunu, Viharamahadevi had a series  of weird  cravings, including the urge to sleep on a pillow  made from  honeycombs.  especially , her urge to drink the water  wont to  wash a sword that had cleaved  the top  of a warrior of Elara, whilst standing  thereon 
 same head, raised the interest of the soothsayers at court, who 
predicted that 'The queen's son, when he has vanquished the Damilas 
(Tamil) and built up a  uk , will make the doctrine to shine forth brightly'. Viharamahadevi gave birth to a son named Gamani Abhaya sometime later, and  then   to a different  child, a boy named Tissa.
Around
 the time of Gamani's birth, 'an elephant of the six-tusked race brought
 his young one thither and left him here and went his way'. Named 
Kandula, he went on to become Gamani's mount and accompanied him through
 much of the prince's adventures.
Dutugemunu's sister
    
"Recent archaeological studies have found evidence proving that King 
Kavantissa had a daughter who was a sister to King Dutu Gemunu".
The battle  within the  palace and early reign
Flag of King Dutugamunu, of Anuradhapura
By the age of sixteen Gamani was 'vigorous, renowned, intelligent and a hero in majesty and might if  a touch  wayward. Determined to expel the invading king of Rajarata, Gamani levied  a military 
 from around Rohana and declared his intention to regain the north to 
his father. The king forbade this stating that 'the land on this side of
 the river is enough' the resulting exchange between father and son saw 
Gamani being dubbed 'Duttha Gamani', his friends fleeing to Malaya, and 
he himself being incarcerated  during a  royal prison.
Kavantissa  is understood  as  an excellent  strategist who recognized early that he needed  to form 
 his kingdom powerful before waging a war against the invaders. He 
assembled armies and made his kingdom prosperous in "rice and betel 
leaf" - this meaning that the people had  tons  of agricultural surplus. The legendary ten "great giants" - men who had great strength – are brought into  the military  at  this point . Kavantissa repeatedly makes Dutugemunu and Tissa swear that  they might  never fight  each other   which   they might  always respect and  hear   the recommendation  of the priests. He also makes the ten giants swear never  to select  sides  during a  war between the brothers.
Upon
 Kavantissa's death, Dutugemunu found himself having to defend his crown
 against his younger brother Tissa, who had seized possession of not 
only the elephant Kandula, but the dowager queen Viharamahadevi  also . The war between  the 2 
 began with a defeat for Dutugemunu at Culanganiyapitthi, where 'many 
thousands of the king's (Dutugemunu's) men' perished. Dutugemunu was 
forced  to escape  back to Mahagama where he levied another army and engaged Tissa in  yet one more  battle  within the  vicinity of  the town .
 Legend has it that as Tissa, fought his brother riding the royal 
elephant "Kandula" against Dutugemunu who rode a mare. Dutugemunu at one
 point made the mare  skip  the elephant causing the elephant  to acknowledge  its master and  plan to  kill Tissa who hastily dismounts via a tree. Dutugemunu was victorious and Tissa was smuggled off the battlefield disguised  because the  corpse of a monk.  it's  said that Dutugemunu recognized the ploy and called  bent  his brother "Are you not ashamed to be carried on  the rear   of those  priests?" 
 Sometime afterwards, however, Dutugemunu and Tissa were reconciled through the efforts of Viharamahadevi  and therefore the  monks, and Tissa became  one among  the king's foremost generals.
Regaining of Rajarata
aving secured his throne, he then planned his operations to regain the north,  including 
 not only Rajarata but numerous smaller semi-independent polities. The 
king's army consisted of 'chariots, troops and beasts for riders', 
soldiers and  variety  of war elephants,  also  as  variety  of monks (to advise the King) and a relic placed in his spear for luck and blessings.  additionally  he was  amid  the famed Ten Giant Warriors who had been recruited from  everywhere 
 the island by his father Kavantissa – Nandhimitra, Suranimala, 
Mahasena, Theraputtabhya, Gotaimbara, Bharana, Vasabha, Khanjadeva, 
Velusamanna, and Phussadeva.

| War Of Dutugamunu and Elara | 
The campaign saw Dutugemunu subduing  variety  of usurping Tamil rulers  within the  north (as many as 32,  consistent with  the Mahavamsa). Of particular interest  is that the  four-month siege of Vijitanagara, where the defending Tamil troops are said  to possess  used 'red-hot iron and molten pitch to panic Dutugemunu's elephants. During  this point , he also married Ran Etana, the daughter of a chieftain who continued to pay homage to Elara of Anuradhapura. On  a minimum of   twice  victory is attributed to the king's 'cunning'  and therefore the 
 bravery of Kandhula. The campaign reached a climax at the eastern gate 
of Anuradhapura, where Dutugemunu, riding Kandhula, finally confronted 
the aged usurped king Elara, on his own elephant Mahäpabbata, and slew 
him with a spear; the encounter is  one among   the foremost  famous in Sri Lankan history.
Dutugemunu's victory at Anuradhapura put him  within the  unprecedented position of ruling nearly  the whole  island of (Sri) Lanka. Despite this however his position was  faraway from 
 problem-free. Elara, despite being an invading Tamil from the Chola 
empire of south India, was renowned as having been a just and righteous 
leader, and Dutugemunu went out of his  thanks to   make sure the  memory of the old king was revered as he cremated Elara and built a tomb for his ashes and made rules for travelers  to urge  off and pay their respects to his tomb. Furthermore, 'looking back upon his glorious victory, great though  it had been , knew no joy, remembering that thereby was wrought the destruction of thousands of both enemies and his soldiers.  this is often  attested to by the sheer number  of spiritual 
 foundations attributed to him by the chronicles (between 68 and 99), 
which include magnificent stupas, monasteries, and shrines.
Reign and construction work

Aside
 from his many construction projects Dutugemunu's reign is memorable for
 his estrangement from his son, Saliya or Salirajakumara. The Prince 
fell  crazy  with  a woman  called Agokamaladevi or Asokamala; unfortunately for all concerned she was of the Scavenger caste,  one among   rock bottom  castes in Sinhalese society. Saliya refused  to offer 
 her up and rejected the throne. Though the Mahavamsa mentions no 
reconciliation, folk stories have the young couple eventually restored 
to the king's good graces.
The king's reign also saw extensive contact between  Sri Lanka  and traders from the west, including Arabs, Persians, and possibly Romans
Following his consolidation of his position Dutugemunu began a series  of giant  construction projects, many of which still survive in Anuradhapura today.  like 
 nearly everything in Dutugemunu's life, each foundation comes with its 
own legend, many of which reveal the preoccupations and inclinations of 
ancient Sinhalese society.
The first foundation mentioned  within the  Mahavamsa  is that the  Maricavatti vihara,  the fashionable 
 Mirisavetiya. Legend has it that traveling to the shore of the Tank of 
Tissa with the 'women of the harem' for a water-festival, Dutugemunu 
planted his spear (which contained a sacred relic)  within the 
 soft ground. When preparing to return to the palace, he found that 
neither he, nor anyone in his retinue, could pull it out. Taking this as
  a symbol  he ordered  the development  of a stupa over the spear.
Dutugemunu also ordered  the development 
 of the Lohapasada, or Brazen Palace, a nine-story chapter house for 
monks, which derived its name from its bright copper-tiled roof. Again, 
legend has it that  the planning  for the palace was  supported  a building seen in  one among  the heavens by  a gaggle  of monks, who drew  the planning  with 'red arsenic on linen' and dispatched it to the king.
Perhaps his most famous creation was the Ruwanweliseya, also  referred to as   the good  Stupa or and Swarnamalee Chetiya,  to deal with  the begging bowl of  Buddha .  the development  was started on  the complete  moon day of the month of Vesak (traditionally the date of the birth, enlightenment,  and spending  away of the Buddha) with the creation of a foundation of  gravel . To hammer the stones into place elephants were used with their feet bound in leather. Dutugemunu  is claimed   to possess  overseen the work personally, being present at  the development  of the relic chamber  and therefore the 
 interring of the bowl itself. The dedication of a stupa is described in
 Chap. 29 of the Mahavamsa, which lists the visit of delegations from 
various parts of India,  also  as a delegation of 30,000 monks from Alexandria of the Caucasus, led by the Indo-Greek monk Mahadharmaraksita.
Other notable works include  the development  of a stupa in Mundeshiwari, current day Bihar, India.
Spiritual relationship with Kataragama Deviyo
Stories  concerning   a number of 
 the king's constructions reflect a spiritual relationship with the 
Kataragama deviyo. Two such sites are Henakaduwa Purana Raja Maha 
Viharaya at Tangalle and Ruhunu Kataragama Maha Devalaya.
During  the amount  of preparations for war with King Elara, the Kataragama deity appeared  ahead  of King Dutugemunu and gave him a sword for him to use  within the  war at  this  day site of Henakaduwa temple (hena and kaduwa, meaning thunder and sword respectively in Sinhalese).
After defeating Elara in single combat  within the  Battle of Vijithapura and subsequently regaining power  within the  country, the Kataragama deity appeared  once more 
 before Dutugemunu while the latter was in meditation at Kiri Vehera, 
Kataragama. The victorious king asked the deity what should be  wiped out  return for the deity's help in winning the battle. The god replied by shooting an arrow  within the  direction of Wedihiti Kanda from Kiri Vehera and instructed Dutugemunu  to create  it a shrine where the arrow lands.
Death and succession
King Dutugemunu  didn't  live  to ascertain  his beloved Ruwanweliseya completed, dying before the plaster work was finished. The Mahavamsa dedicates  a whole  chapter to his death, which contains a poignant scene where the dying king is taken by palanquin to the vicinity of  the unfinished 
 stupa. There he also encounters his old colleague Theraputtbhya, now a 
monk. After some discussion of the mortality of men, the aged monarch 
passes away and  is instantly  reborn  within the  heavenly realm of Tusita.
A
 common folk tale surrounding the death of King Dutugemunu is that as he
 was dying he was told that Ruwanweliseya was completed  so as   to stay 
 him happy. The well-intentioned plan went awry, however, when 
Dutugemunu asked to be shown the finished building. His brother Tissa 
had  the whole  building draped in white cloth to present the illusion of whitewash, and  thanks to  his failing eyesight Dutugemunu  didn't  spot the difference, dying convinced that the building was finished.
Following his death Dutugemunu was succeeded by his brother Saddhatissa,  instead of  his disinherited son Saliya.
