The electoral district of Amsterdam IX was created in 1897, when the district of Amsterdam, like all other remaining multi-seats districts, was split into single-member districts. The territory of Amsterdam IX roughly corresponded with the neighbourhoods of Oud-West, Frederik Hendrikbuurt and Staatsliedenbuurt, all located in the current borough of Amsterdam-West.[1][2]
Due to Amsterdam's rapid urban expansion into the district's boundaries, its electorate grew rapidly, from just 5,215 in 1897 to 27,317 in 1917, making it the largest electorate of any district at that time.[3][4]
In its inaugural election, the district of Amsterdam IX elected the former Liberal Minister of the Interior Johannes Tak van Poortvliet. However, Tak van Poortvliet was also elected in the district of Beverwijk and opted to represent the latter, thus triggering a by-election in Amsterdam IX in which the Liberals held the seat. In 1901, the district elected Cornelis Lely, but he resigned a year later following his appointment as Governor-General of Suriname. In the subsequent by-election, the Anti-RevolutionaryHendrik Bijleveld narrowly defeated Social Democratic (SDAP) leader Pieter Jelles Troelstra in the runoff, becoming the only representative from the parliamentary right in the district's existence. Amsterdam IX was won by the Free-thinking Democratic League in 1905, and was represented by the SDAP from 1909 until its abolition in 1918.
