Raja Hijau or Ratu Hijau (; ), also spelt Raja Ijau, was a Malay sovereign queen of Patani who reigned from 1584 to 1616. Her name means "the Green Queen" in English. She was also known as the 'great queen of Patani'. Her rule in Patani ushered in the golden age of Patani. Early life Raja Hijau was the eldest of three daughters of Sultan Mansur Shah. There is no mention of her being married in historical accounts, but some have speculated that she married the Chinese pirate Lin Daoqian who was said to have married a Sultan's daughter in Patani. Her younger brother Bahdur succeeded to the throne aged 10, but was murdered in 1584 by his half-brother who was in turn killed. Reign According to the Portuguese chronicler Mendez Pinto, she came to the throne in 1584 as a sister of the murdered Patani king after twenty years of instability in the country. There was apparently a lack of male heirs as a number of them were murdered in this period of political turbulence and violence. Raja Hijau adopted the title of peracau derived from the Siamese royal title phra chao. Early in her reign she saw off an attempted coup by her prime minister, Bendahara Kayu Kelat. She ordered that a dam be built to divert water to a dug channel to ensure supply of water to Patani. She ruled for 32 years, and brought considerable stability to the country. During her reign, trade with the outside world increased, and European traders such as the Portuguese and Dutch came to the port. The majority of the merchants were said to be Chinese merchants, of which the most important of them, such as the leading commercial official Datu Sirinara, had converted to Islam and adopted Malay court etiquette. The first Dutch Company agents visited this region of what is now southern Thailand during her reign in 1602, while the English arrived in 1612. According to Jacob van Neck's writing in 1604, he reported a relatively prosperous state under Raja Hijau, who was "one well-disposed to merchants". The arrival of the European also led to conflicts, and the Dutch attacked English ships in Patani, which led to the withdrawal of the English from Patani even though Raja Hijau ordered that the English be protected. Nevertheless, as a result of increasing trade, Pattani prospered. European visitors to Patani were impressed
