The Figure of the East Java Warlord Whose Fate Ended Tragically

The success of an individual in controlling and leading a region often relies on the ability to execute strategic moves. It is not surprising that, in pursuing such strategies, some resort to any means necessary—driven by the ambition to dominate, lead, and become a central figure. These methods may include acts of thuggery or other cunning schemes. Although the term ‘preman’ (thug) only became widely known in the 17th century, adapted from the Dutch colonial term ‘vrijman’ (free man), similar tracks of activity have existed since the era of ancient kingdoms thousands of years ago.

One of the oldest recorded criminal figures or warlords in the history of the Nusantara archipelago is Ken Arok, also frequently written as Ken Angrok. In the classic tale of the Pararaton from the 16th century, Ken Arok is described as being born to a farmer. He was subsequently abandoned by his mother and taken in by a thief, who raised him.

However, this thief did not raise Ken Arok with the positive lessons typical of a parent; instead, he taught Ken Arok to follow in his footsteps into the criminal underworld. As a child, Ken Arok obediently followed the commands of his foster parent. From this point, he engaged in gambling, theft, robbery, and even murder. These actions repeatedly made him a target for arrest by the ruler of Tumapel, Tunggul Ametung, who was unsettled by these acts of what would today be termed thuggery.

Ken Arok’s prowess as a warlord made him a significant figure, to the point that Tunggul Ametung eventually made him a trusted confidant. Consequently, Ken Arok’s name became known throughout Tumapel as a formidable figure who supported the existing power structure. As recounted in the Sejarah Nasional Indonesia (1993), this great popularity fuelled Ken Arok’s ambition to rule. He sought to achieve this by marrying Tunggul Ametung’s wife, Ken Dedes, after receiving a prophecy that marrying her would lead to him becoming the ruler of Java.

To this end, he commissioned the blacksmith Empu Gandring to forge a kris (dagger), which was intended to be used to assassinate Tunggul Ametung. However, due to his impatience, Ken Arok’s thuggish nature surfaced; he used the unfinished kris to kill Empu Gandring instead. He then handed the weapon to a Tumapel nobleman, Kebo Ijo, as a deceptive tactic. Later, Ken Arok murdered Ametung using that very same kris. At this juncture, Ken Arok escaped suspicion because everyone believed the weapon belonged to Kebo Ijo. Kebo Ijo was arrested, while Ken Arok, through his cunning, successfully became the ruler of Tumapel in 1222.

Later, Tumapel became known as the Singasari Kingdom, with Ken Arok as its first king. The ambitions of the man, born in 1182, did not end there; he sought to control the entirety of East Java, leading to an attack on the Kediri Kingdom (1042–1222). The attack was successful, resulting in the collapse of the Kediri Kingdom and the expansion of Ken Arok’s territory, establishing him as the ruler of East Java in the early 13th century. The Pararaton chronicles state that Ken Arok’s reign, which began as a warlord of ancient Java, lasted for over 20 years, from 1222 to 1247 AD.

The life of Ken Arok is said to have ended in 1247 AD, following his assassination by an agent of Anusapati—the biological son of Tunggul Ametung, the man Arok had previously murdered. Anusapati carried out this act of vengeance and eventually ascended to the throne, just as his father had done.
