H.Don Carolis & Sons
As dowry, Don Carolis received a furniture shop in the Pettah, which became H. Don Carolis & Sons Ltd, one of the largest and reputed furniture companies in Asia. In 1886 H.Don Carolis & Sons exported furniture to Australia. An Indo-Afric syndicate was formed in London in 1895 to carry out a large furniture business with South Africa. This led to the establishment of the firm‘s first factory, 'Steam Furniture Works' in Slave Island. The firm became the dominant furniture maker in the country. By the turn of the century, the firm was exporting to Australia, South Africa, India, Burma, England, Europe & the USA. Don Carolis obtained Gold and Silver medals for furniture exhibited at the Ceylon Agricultural Exhibitions, the Indian Industrial Exhibition of 1901, the Paris Exhibition of 1900, and the Saint Louis Exposition of 1904.
Buddhist revival
Until 1884, Buddhists were forced by the colonial authorities to declare themselves Christian. This was changed after Col. Henry Steel Olcott made representations to Secretary of State for the Colonies in London on behalf of the Buddhists of Sri Lanka. The Buddhism Protection Committee was formed in January 1884 under the patronage of Colonel Olcott, mainly with the objective of getting the Vesak full-moon day holiday restored. The British had not shown any interest in restoring the Vesak holiday which the Buddhists lost in 1770 during the Dutch rule. Dharmagunawardena was elected President with Don Carolis as Vice President. In 1885 the Vesak holiday was restored and the committee elected a steering committee, to which Don Carolis and his father-in-law were again elected, which went on to design the Buddhist flag.
