The group's origin dates back to 1948 when Thanpuying Chanut Piyaoui opened her first hotel, the "Princess", in Bangkok. It had only 30 rooms but had the distinction of being the first modern hotel in Bangkok with a swimming pool. The company takes its name and much of its character from the ideas of
King Rama VI, whose thoughts on the modern state blended Western and Thai influences. In 1970, the 23 storey
Dusit Thani Bangkok became the company's first flagship hotel. The 510-room hotel was the first luxury hotel and the tallest building in Bangkok for several years. In 1987, Dusit acquired its first resort property, Dusit Thani
Pattaya, followed by another beach resort in
Phuket Province, the Dusit Thani Laguna Phuket. In 1989, Dusit Thani
Hua Hin, formerly known as the Dusit Resort and Polo Club, opened. by purchasing shares in the holding company, Philippine Hoteliers, Inc. (PHI), from Japan Airlines Development Company Limited and JAL Trading Inc. After the acquisition, the Hotel Nikko Manila came under the management of Dusit Thani Hotels and Resorts, and was renamed the Dusit Hotel Nikko,
Manila. The Manila hotel underwent a major renovation programme and became Dusit Thani Manila in April 2008. It is known for the
Supreme Court ruling on "Illegal Strike" which considered the shaving of heads by the employees of Dusit Hotel as tantamount to committing strike. The issue has been protested widely in the Philippines especially with the
International Labour Organization's findings that the Philippine government and the Supreme Court violated the workers' right to freedom of expression and association and redefined the meaning of strike. In November 2006, Dusit Thani added a brand extension, the Dusit Lifestyle Collection with dusitD2 hotels and resorts. dusitD2 is the second generation brand of Dusit Thani Hotels and Resorts. The first property in the dusitD2 collection opened in November 2006 in
Chiang Mai. The second dusitD2 hotel, dusitD2 Baraquda Pattaya, was opened in February 2009. Dusit International's portfolio includes Dusit Princess Hotels and Resorts. The rebirth of the original Princess hotel came with the 1989 opening of the Royal Princess Larn Luang, Bangkok. There are seven Dusit Princess properties in Thailand. The first Dusit Princess outside Thailand, Dusit Princess City Centre,
Dubai, opened in December 2009. Dusit Thani Dongtai was the first Dusit Thani to launch in China. Dusit Thani Fudu Qingfeng and dusitD2 Fudu Binhu Hotel also opened in 2016 followed by Dusit Thani Dongtai. The group's other business are hotel management of both Thai and overseas properties, and education, through the
Dusit Thani College and a Bangkok culinary school joint venture with
Le Cordon Bleu of France. In 1993, Thanpuying Chanut founded Dusit Thani College. In 2009 it initiated a programme with
Lyceum of the Philippines University. Additionally, the college opened its new campus in
Pattaya in 2011. Besides these, The Dusit Executive Development Center (DEDC) was established in 2005 as a subsidiary of Dusit Thani Public Co., Ltd. to provide executive training and development courses to individuals and various organisations. The dusitD2 Hotel in
Nairobi was the scene of the
2019 Nairobi hotel attack. In April 2018, Dusit International introduced a new mid-market brand called ASAI Hotels. In August 2025, Dusit Hotels brand was launched, with three properties already operating under Dusit in Doha, Hanoi, and Chengdu. ==Dusit Central Park==
