The aim of this study has been to investigate why we saw the formation of the green party and junilistan in Swedish politics. The questions being asked is why the individuals behind the party decided to take the step towards forming a new party as well as why they felt it worth forming it.

The theories being used is the sequential model created by Gissur Ó Erlingsson, which is complemented with theoretical assumptions by Paul Lucardie. The sequential model illustrates the party forming processes in three steps, which then through process-tracing allows for the identification of events that have exerted an influence on the entrepreneur to decide taking the step towards forming a new party. With the help of Lucardie I presented assumptions which gave me possibility to investigate why they then felt it worth forming the new party.

The conclusion showed that the step toward party formation in both cases occurred when the entrepreneurs experienced that their demands where not met. The second question was divided in to two sub questions which showed that the entrepreneurs in both cases made the calculation that a new party would find support amongst the electorate but regarding the ability to finance and attach competence the result was more diverging.
