BIJ1

Bij1 (, ), stylised as BIJ1, formerly known as Article 1 (), is a political party in the Netherlands. It is described as socialist and is on the left-wing to far-left of the political spectrum. It was founded in Amsterdam in 2016 by Sylvana Simons, a media personality and politician who was formerly briefly connected to another party, Denk. Bij1 saw a breakthrough during the 2018 municipal elections and 2021 Dutch general election in which it won representation in parliament but went through a long period of internal unrest and instability after. Former GroenLinks politician Tofik Dibi has led the party since August 2025.

== History == === Foundation === In 2016, Sylvana Simons joined Denk, a political movement founded by MPs Tunahan Kuzu and Selçuk Öztürk after leaving the Labour Party following an internal dispute over the party's position on integration. Simons agreed to act as a communications advisor for the party at the invitation of Kuzu and announced her intention to join Denk's candidate list for the next general election. However, in December of the same year Simons left the movement and later said she was disappointed by the lack of support she received from the party during a period of intense death threats and argued Denk was more focused on media publicity. She also felt that Denk was becoming increasingly conservative and losing interest in progressive causes such as LGBT rights.
