As Portuguese, Spanish loanword come from colonialism in East Indies. In 1606, the Spaniards established some form of trade links with the Maluku Islands. Manado was further developed by Spain as a centre of commerce for the Chinese traders who traded the coffee in China; with the help of native allies, the Spanish took over the Portuguese fortress in Amurang in the 1550s, and Spanish settlers also established a fort at Manado so that eventually Spain controlled all of the Minahasa. In 1529, Charles I of Spain relinquished all claims to the Spice Islands to Portugal in the treaty of Zaragoza. Thus, there are fewer loanwords from Spanish than Portuguese or Dutch.
