Topasses (Tupasses, Topas, Topaz) were a group of people led by the two power families – Da Costa and Hornay – that resided in Oecussi and Flores. The Da Costa families were descendants of Portuguese Jewish merchants and Hornay were Dutch.
Topasses were found in the various places of South Asia and Southeast Asia which were frequented by the Portuguese, such as Goa, Malacca and Batavia. In particular they are associated with the ethnically mixed Portuguese group that dominated politics on Timor in the 17th and 18th centuries.
Topasses (Topaze Indo-Portuguese) was a term applied in India by the British East India Company in the eighteenth century to describe Luso-Asians - usually from the Portuguese territories in the Indian subcontinent, or formerly Portuguese territories such as Bombay. One of the first references to them is in the British Anti-piracy campaign of 1756 when 300 Topaze Indo-Portuguese on the British ships Kent, Kingfisher and Tyger captured the fortress of Geriah on 14th February 1756. 
Topass (Topass, Topass Seaman or Topas) was a term used by the British Merchant Navy for the man who acted as an interpreter for a group or gang of Lascars or South Asian seamen on British vessels since at least the mid nineteenth century. Usually the man came from the Luso-Asian communities, such as those from Goa and Bombay, and could speak English (and often Portuguese) to pass on instructions to a group of sailors and to report back or mediate between Lascars and the European crew.
The etymology of the name is obscure. It might come from the Tamil term tuppasi, "bilingual" or "interpreter". But it has also been associated with the Hindi word topi (hat) which refers to the characteristic hat worn by the men of this community as a marker of their cultural attachment to the European community. Hence, they are also referred to as gente de chapeo in Portuguese accounts or as gens à chapeau in French accounts. It partly overlapped with the Dutch concept mardijker, "free men", who also usually had a Portuguese cultural background, but had no European blood in their veins.
Impact on the Timor region
As a political entity in the eastern part of Insular Southeast Asia, they arose with the Portuguese settlement on the small Island of Solor (from the 1560s), using Solor as a stepping-stone to the trade in sandalwood on Timor. When the Dutch East India Company conquered Solor in 1613, the Portuguese community moved to Larantuka on Flores. In spite of continuous hostilities with the Dutch, the Topasses managed to obtain a steady foothold on Timor after 1641, and part of the population of Larantuka moved over to West Timor in the late 1650s, as a response to the establishment of the VOC in Kupang in 1653. They were able to defeat Dutch military expeditions on Timor with the help of Timorese allies, in 1653, 1655, 1656 and 1657.
The peace treaty between the Kingdom of Portugal and the Dutch Republic in 1663 removed the acute threat from the latter. By this time the Topasses consisted of an ethnic mix of Portuguese, Florenese, Timorese, Indians, Dutch deserters, etc. Through their military skills they were able to dominate large parts of Timor, with their center in Lifau in the present-day Oecussi-Ambeno enclave.
Independent position within colonial system
The Topass community was led by their own appointed captains, and had little contact with the Viceroy of Portuguese India. They pressed Timorese princes to deliver sandalwood to the coast, which was sold to merchants from the Portuguese colony of Macau or to the Dutch. In 1641, their leader Francisco Fernandes led a Portuguese military expedition to weaken the power of the Muslim Makassarese who had recently made inroads on Timor. His small army of musketeers settled on Timor, extending Portuguese influence into the interior. After 1664 the Topasses were governed by the Hornay and Costa families, who held the titles captain-major (capitão mor) or lieutenant general (tenente general) in turn. The Portuguese appointed an administrator to Lifau in 1656 and in 1702 the Portuguese authorities installed a regular governor in Lifau, a move that was violently opposed by the Topass community. The Topasses had become a law unto themselves, and drove out the Portuguese governor António Coelho Guerreiro in 1705. After more attacks from the Topasses in Lifau, the colonial base was moved east to Dili in eastern Timor in 1769. For long periods up to 1785, a state of warfare existed between the two Portuguese groups.
Decline of the community
In 1749 a political crisis involving Topass leader Gaspar da Costa resulted in another war with the Dutch. When he marched on Kupang with a considerable force he was routed and killed at the Battle of Penfui, after which the Dutch expanded their control of western Timor. Many Timorese princedoms which had hitherto been subordinated to Topass authority now fell away and allied with the VOC instead. The Topass still managed to hang on in Oecussi, and killed the Dutch commander Hans Albrecht von Plüskow in 1761, when he attempted to expand the Dutch sphere on Timor. Their power nevertheless receded by the late 18th century, due to diminishing economic and political opportunities. Still neither Portuguese nor Dutch colonial influence could be firmly established on Timor until the 19th century and only with continuous and heavy military force. The concept Topass disappears from the records in the 19th century. Between 1847-1913 the Portuguese had to mount more than 60 armed expeditions in order to subdue the Timorese in the interior of the island; a few of these revolts occurred in the old Topasses part, west of East Timor. Hornay and Da Costa descendants continued to govern locally as Rajas (or Liurais) of Oecussi up to modern times.
During the early 1900s, the enclave of OeCussi was ruled by Dom Hugo Da Costa and Rainha Elena Hornay - Their Children Domingos died at a young age. Their daughters Teresa Hornay da Costa married Sena Barreto and Rosa Anacleta Hornay da Costa married João Martins. Unfortunately, João Martins died in Ossu a few months before thebirth of their son João Martins. Rosa Hornay da Costa later married João Vidigal and gave birth to a daughter Maria dos Anjos Vidigal.
Rosa Hornay Da Costa Vidigal died in Darwin in August 1990.
Rainha Elena Hornay died in Dili and Dom Hugo Da Costa remarried later to Ana maria da Cruz and had 5 children - João da Costa, Maria da Costa, Francisca da Costa, José da Costa and Maria Ana da Costa.
Maria Ana da Costa currently resides in OeCussi.
