Bendahara (Jawi: بنداهارا) is an administrative position within classical Malay kingdoms comparable to a vizier before the intervention of European powers during the 19th century. A bendahara was appointed by a sultan and was a hereditary post. The bendahara and the sultan shared the same lineage.
Today, it still used in Brunei where it is known as Pengiran Bendahara.
The closest post which is comparable to the post of the vizier as the Malay kingdoms are Islamic kingdoms. As the bendahara is the head of the nobility, the status confers certain responsibility. The bendehara is the backbone of the Malay Sultanate. For the ancient kingdom of Malacca and Johor, there are many tasks and responsibilities but the primary ones are:
Legitimacy of the Sultan lies with the bendahara. The bendahara always consulted the other nobles before arriving at a decision. The bendahara and nobles do this for the well-being of the subjects and is essential if there are problems in the state. These tasks are more extensive than any vizier or the modern prime minister.
The involvement of the British and the Dutch in the administration of the Malay States and the subsequent independence of Malaysia and Indonesia has reduced the Bendehara to a symbolic title only.
In modern times, it is typical to render the position as prime minister. Though a bendahara's duties are similar to that of a prime minister's, the two terms are not interchangeable. One clear difference is the amount of power held by the two positions. In ancient times, the bendahara was typically the highest-ranking official after the sultan but the sultan retained ultimate authority. The sultan was not answerable to the bendahara, or to anyone else for that matter. The sultan was not just a constitutional monarchy like the Yang di-Pertuan Agong in contemporary Malaysia where the Prime Minister holds effective political power.
Though it is unclear when the title was first used, the Sultanate of Malacca had several influential bendaharas. The most famous is Tun Perak. Under Tun Perak's service which spanned several sultans, Malacca reached its height in the late 15th century. According to the Malay Annals and the Hikayat Hang Tuah, the bendahara secretly saved the life of Hang Tuah, a laksamana the sultan had ordered killed.
