At the end of the 1630s, Dutch East India Company (Verenigde Oostindische Compagnie or VOC) power was already spreading into Erlin (二林) and Huwei (虎尾). The Dutch were thus aware of a single authority among the villages in the central region. After the VOC conquered Quelang (雞籠, now Keelung [基隆]) and Tamchuy (淡水, now Danshui) in 1642, the company wanted to use roads to connect Tayouan (大員, now Anping [安平]) and Tamchuy. The VOC decided to use military force to confront the villages along Taiwan’s western coastal plain which had not yet submitted, including the middle region which was under Quataong’s command.
In 1644 the VOC assigned the officer Pieter Boon with the first military campaign. From Quelang and Tamchuy, Boon would head south to conquer and pacify Nankan and Zhuqian (竹塹, now Hsinchu [新竹]). After razing the villages of the Boder (水裏社) and Passoua (半線社) peoples, Boon returned to his starting point. However, Boon had been unable to force Quataong to submit. In January of 1645, the officer Pieter Boon commanded of a fleet of ships and more than 200 soldiers on a second military campaign. In one stroke the Dutch conquered villages from Teyowan to Danshui, pacifying 13 villages, killing 126 people, and capturing 16 children. All of the villages under Quataong’s control were subdued by the VOC. On April seventh, Aslamie went to Saccam (赤崁, or Chikan, now Tainan [臺南]) to submit to the VOC. Aslamie was unable to attend the northern Taiwan native assembly meeting (Landdag, 地方會議) because of timing, but he did attend the southern Landdag meeting which took place slightly later. Aslamie formed a contract with the Dutch and received a rattan cane as a symbolic gesture. The VOC acknowledged Aslamie’s role as a local leader, similar to the leader of Langjiao (瑯嶠). Aslamie died in 1647 or 1648 and was succeeded by his sister’s son Kamachat Maloe. The title “Quataong,” which appears in some documents, was not appended to Kamachat Maloe’s name.
During Zheng Chenggong’s (鄭成功) 1661 assault on Tayouan, his troops were looking everywhere for more resources, and Kaujong (狗讓) of Kamachat’s Dorida people began to rebel. In 1664 a second revolt was launched, but this time it was completely suppressed by Zheng’s troops. Under great pressure from the Zheng clan, the power of the Dorida people gradually weakened. By 1731 and 1732 (9th-10th years of Yongzheng [雍正] Emperor) when the rebellions of the Dajiaxi [大甲西]) and other descendents of the Dorida people had been suppressed, the influence of their lineage was almost totally eliminated.
