Dutch pacification campaign on Formosa: Soldiers from the Dutch East India Company razed the village of Mattou, now part of modern-day Tainan, Taiwan.

A series of military actions and diplomatic moves were undertaken in 1635 and 1636 by the Dutch East India Company (VOC) in Dutch-era Taiwan (Formosa) aimed at subduing hostile aboriginal villages in the southwestern region of the island. Prior to the campaign the Dutch had been in Formosa for eleven years, but did not control much of the island beyond their principal fortress at Tayouan, and an alliance with the town of Sinkan. The other aboriginal villages in the area conducted numerous attacks on the Dutch and their allies, with the chief belligerents being the village of Mattau, whose inhabitants in 1629 ambushed and slaughtered a group of sixty Dutch soldiers.

The United East India Company, commonly known as the Dutch East India Company, was a chartered trading company and one of the first joint-stock companies in the world. Established on 20 March 1602 by the States General of the Netherlands amalgamating existing companies, it was granted a 21-year monopoly to carry out trade activities in Asia. Shares in the company could be purchased by any citizen of the Dutch Republic and subsequently bought and sold in open-air secondary markets. The company possessed quasi-governmental powers, including the ability to wage war, imprison and execute convicts, negotiate treaties, strike its own coins, and establish colonies. Also, because it traded across multiple colonies and countries from both the East and the West, the VOC is sometimes considered to have been the world's first multinational corporation.

Madou District is a district of about 43,071 residents in Tainan, Taiwan. It owes its name to the Siraya language word Moatau or Mattou. Mattau was one of the four core Sirayan villages during much of Taiwan's colonial history and figured heavily in the formation of colonial policy in Dutch Formosa. Currently, it is a well-known town in Tainan for its local culinary specialties and historical sites, and has become more prosperous in recent five years due to the presence of two universities. As an example of the increased attention Madou is receiving, the New Year Countdown Night for 2006 in Tainan was held at Madou Junior High School.
