Portuguese Empire in the Indonesian Archipelago
The Portuguese were the first Europeans to establish a colonial presence in the Indonesian archipelago. Their quest to dominate the source of the spices that sustained the lucrative spice trade in the early 16th century, along with missionary efforts by Catholic orders, saw the establishment of trading posts and forts, and left behind a Portuguese cultural element that remains in modern-day Indonesia.
