In the short term, the 1906 Dutch invasion in Bali, and its sequel in 1908, sealed the Dutch control of the island. The Dutch invasion however was followed closely by media coverage, and reports of the bloody conquest of the southern part of the island filtered to the West. The disproportion between the offense and harshness of the punitive actions was pointed out. The image of the Netherlands as a benevolent and responsible colonial power was seriously affected as a consequence. The Netherlands, also under criticism for their policies in Java, Sumatra and the eastern island, decided to make amends, and announced the establishment of an "Ethical policy". As a consequence, the Dutch in Bali turned students and protectors of Balinese culture and endeavored to preserve it in addition to their initial modernization role. Efforts were made at preserving Bali culture and at making it a "living museum" of classical culture, and in 1914, Bali was opened to tourism. The very harshness of the 1906 and 1908 military invasions thus paradoxically triggered an international uproar which contributed to the preservation of Bali's culture, to make the island one of the most popular tourist destinations today.
