It is a classical argument that how parties are born affects how they die. Nevertheless, few studies theorize and rigorously estimate the impact of formative features on the risk of organizational death. Using a life cycle perspective, we theorize how and when party mortality is shaped by four formative features constituting parties’ heritage: insider status, societal rootedness, ideological novelty, and roots in preexisting parties. To assess the dynamic influence of these formative features on party death, we fit a state-space duration model to a data set covering 204 party trajectories in 22 consolidated democracies. Our modeling approach outperforms conventional methods and yields results that contradict the notion that formative features lose relevance as parties age. Our findings indicate that insider status affects mortality risk toward parties’ midlife, societal rootedness matters early and late in parties’ trajectories, while the combination of ideological novelty and roots in preexisting parties matters throughout parties’ life spans.
