During the 1913 Dutch imperial festivities Indo-Europeans of the ‘’Indische’’ party drove through white (totok) neighbourhoods in the big cities waving the IP banner.
[4] To the great dismay of the authorities It still called for independence of the Dutch East Indies, “free of foreign tyranny” and defended the interests of indigenous and Indo people alike.
[5] Dutch communist leader Henk Sneevliet co-founder of the ISDV, who had arrived in Java in 1913 initially believed ‘’Insulinde’‘ could be an effective vehicle to disseminate the socialist ideals and agenda in the colony.
Cooperation with the ISDV was ended in 1917 on the grounds that Insulinde believed that the Dutch leadership of that party was trying to drive a wedge between the Indigenous and Indo people.
By June 1919 Insulinde had a membership of 17,000 members and was well represented in the Volksraad (Dutch East Indies) where it maintained close ties with Budi Utomo and the Sarekat Islam.
[9] When NIP membership numbers dropped, many of its Indo-European members joined the 1919 established Indo European Alliance (IEV), founded by Douwes Dekker's former colleague, friend and associate Karel Zaalberg.
