This is the author accepted manuscript. ; It is a classical argument that how parties are born affects the way they die. However, few studies have theorized and rigorously estimated the impact of central formative features on the risk of organizational death over the course of parties' entire lifespan. 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 pre-existing parties. We fit a state-space competing risks model to a new dataset covering 204 party trajectories in 22 consolidated democracies to assess the dynamic influence of these formative features on two distinct types of death: dissolution and merger. Our flexible approach to modelling time dependency outperforms conventional methods and generates novel insights about the time-varying relationship between party heritage and mortality fundamental to whether party renewal is likely to enhance democracies' representative capacity.
