The number of Protestants and Muslims declined significantly after September 1999 because these groups were disproportionately represented among supporters of integration with Indonesia and among the Indonesian civil servants assigned to work in the province from other parts of Indonesia, many of whom left the country in 1999. There are also small Protestant and Muslim communities. The Indonesian military forces formerly stationed in the country included a significant number of Protestants, who played a major role in establishing Protestant churches in the territory. Fewer than half of those congregations existed after September 1999, and many Protestants were among those who remained in West Timor. The Assemblies of God is the largest and most active of the Protestant denominations.
